Description

  The present invention relates to a gas boil device that makes a boiled state in a short time without losing useful components such as umami components, a drying device that dries the article after gas boil, Transfer material sterilizer that sterilizes in a short time in an atmosphere, gas boil method that makes an article boiled in a short time without losing useful components such as umami ingredients, and transfer that sterilizes in a short time in a gas atmosphere while transferring the article The present invention relates to an object sterilization method.

  In order to dry small fish such as anchovy mushrooms, sardines, shirasu, small shrimp, etc. (hereinafter referred to as small fish) to boiled and chilled fish, dried shrimp, etc., boiled small fish just caught under atmospheric pressure (Boiling) and drying to dry. Boiled with hot water exceeding 60 ° C. is sterilized, and if the moisture content becomes 40% or less by subsequent drying, bacteria do not propagate and it becomes difficult to rot.

  For this reason, the conventional simmering device is configured to make a hot water runway with a length of 20 m, to feed small fish as material from one end, and to boil in about 2 minutes before reaching the end. (See Patent Document 1). The boiled liquid used is heated salt water. The steam of the boiler is passed through the smoke pipe, heat is exchanged between the smoke pipe and the boiling liquid, and the salt concentration is controlled.

  Further, as a conventional drying apparatus, an apparatus that uses an endless spiral conveyor device to dry small fish or the like while being transported endlessly is known (see Patent Document 2). This drying device has a conveyor guide rail whose shaft core is provided in a spiral shape in the vertical direction, an endless spiral conveyor that moves spirally along the conveyor guide rail, and a drive that runs the endless spiral conveyor so as to endlessly circulate. The heat source and the like are arranged at the center of the spiral inside the endless spiral conveyor device, and the fish is dried while being transported endlessly.

  The article to be dried after boiling is not limited to small fish. Boiled rice cakes, rice cakes, etc. are dried after boiling to make bonito, bonito, etc. Many foods are boiled and used as they are. For example, seafood such as salmon, salmon, shrimp, and vegetables such as spinach are boiled and used as they are. These foods are also boiled using a boiled pot or a simmering device.

  The boiled device described above boiles materials such as small fish to kill germs, but the purpose of the boil is not limited to this, but rather it can be dried for a long time by drying it later. In addition, this is to obtain a new taste of dried fish. In this respect, boiling by a conventional simmering apparatus performs sterilization as a pretreatment, but is different from heating for sterilization such as boiling medical instruments.

  By the way, the sterilization performed conventionally is not restricted to such sterilization with hot water. For example, irradiation sterilization that sterilizes by irradiating gamma rays, ultraviolet rays, or ultrasonic waves, sterilization methods that use sterilizing substances such as chemicals and ozone, pressurization that sterilizes heat-resistant spore bacteria by applying ultrahigh pressure such as several hundred MPa There are sterilization methods.

  However, these sterilization methods are large-scale and require special equipment, or those that require long-term sterilization in an isolated environment, and are suitable for scientific experiments and medical purposes. It is. It is extremely difficult to use these sterilization methods for a simmering apparatus, a drying apparatus, or the like that heat-treats small fish or the like in an open environment at the seaside and then dries them over time. In boiled pots and simmering devices, if the material is not processed in a short period of time, the color and taste will be lost. In addition, low cost, simple structure and space are not required, and good operability is desired. If it cannot be processed, it is not practical.

Japanese Unexamined Patent Publication No. 2000-175816 Japanese Patent Laid-Open No. 10-157820

  The conventional simmering apparatus such as Patent Document 1 boiles articles such as small fish with hot water, so heat is transferred to the tissues (proteins, etc.) inside the article, and the hot water penetrates and heat denaturation proceeds, Useful ingredients such as vitamins decompose or escape into hot water. In some cases, nearly 3/4 of the useful components are lost, so when tasted in this state, the taste becomes watery. Subsequent drying changes the protein to some amino acids, which forms a new umami component that makes it feel delicious, but due to the denatured components and proteins that have disappeared in the hot water, the original taste of the material is quite There was a problem of being lost.

  In addition, in the conventional drying apparatus, if the drying is performed rapidly after boiling, the small fish can lose its moisture and lose its commercial value. There was a problem that the cost for this must become very large because it had to be dried uniformly. And if a drying apparatus like patent document 2 is used, a small fish will roll by the effect | action of the wind for gravity and a drying, and it will not be forming the layer of the small fish of uniform thickness, but it can dry and install. However, a large space was necessary.

  As for sterilization, when sterilization is performed using a heat sterilizer, bacteria such as E. coli contained in seafood, vegetables, meat and other foods are generally boiled at 60 ° C to 75 ° C for at least 10 to 30 minutes. Sterilization is possible. In rare cases, fish and shellfish may be contaminated with Vibrio parahaemolyticus, etc., and mammals and birds may be contaminated with Salmonella or the like. However, spore bacteria such as Clostridium botulinum and Clostridium perfringens that may be contained very rarely do not die if boiled at 60 ° C. to 75 ° C. for 10 to 30 minutes. It is said that it cannot be sterilized unless it is heated at a temperature of at least 100 ° C. to 120 ° C. for several tens of minutes to several hundred minutes.

  Now, even if it can be sterilized with a heat sterilizer, heating at a temperature of 60 ° C. to 75 ° C. for 10 minutes to 30 minutes is inefficient for processing a large amount of articles. That is, only a static predetermined amount of sterilization is repeated, and the process is not dynamic and continuous. Therefore, if the heating temperature is increased and the heating time is shortened, the processing amount may be increased and the efficiency may be improved. However, in the case of the above-described conventional simmering device, if the heating temperature is simply increased, the umami component and other useful components Is lost, the protein is denatured, and the color, taste, texture, etc. of the food are impaired, making it unusable. Furthermore, when this heating sterilizer is used to thoroughly heat at a high temperature of 100 ° C. over several times to several tens of times the above time, the quality as food is completely impaired. The above-mentioned purpose cannot be achieved, a long processing time is required, and a large amount of articles cannot be processed continuously.

  And in this heat sterilization apparatus such as a conventional simmering apparatus, at least inherently, a large amount of articles are heated at a temperature of 100 ° C. to 120 ° C. for several tens of minutes to several hundreds for sterilization of spore bacteria. It is impossible. From such a background, there is a transferred material sterilizer capable of continuously heating a large amount of articles at a temperature of 60 ° C. to 100 ° C., and in some cases 100 ° C. to 200 ° C. for a long time by transferring the articles. desired.

  Hereinafter, the gas boiling apparatus of Example 1 of this invention is demonstrated based on drawing. FIG. 1 is a conceptual front view of a gas boil device in Embodiment 1 of the present invention, FIG. 2 is a control block diagram of the gas boil device in Embodiment 1 of the present invention, and FIG. 3 is a boil state of a target article in Embodiment 1 of the present invention. It is a conceptual diagram.

  First, the gas boil apparatus in Example 1 of this invention is demonstrated based on drawing. The gas boil device shown in FIGS. 1 and 2 conceptually shows a device in the case where the circulation of the gas in the heating chamber is performed by a push-in fan. A specific configuration in the case of using a suction fan will be described later. 1 and 2, reference numeral 1 denotes a high temperature and humidity high temperature and humidity, and high humidity and high temperature air (high humidity and high temperature gas according to the first embodiment of the present invention) adjusted to a high temperature corresponding to an article boil. This is a heating chamber in which a target atmosphere containing moisture such as small fish, vegetables, salmon, salmon, etc., which is transferred in the gas atmosphere, is boiled. The article boiling corresponding temperature and the article boiling corresponding humidity will be described later. Next, 2a and 2b are blending chambers for adjusting the temperature and humidity of the high-humidity high-temperature air blown into the heating chamber 1, and the ratio and temperature of the heated air and water vapor supplied for mixing are controlled. 3 is an endless conveyor for placing and transporting articles, 3a is an endless net of the conveyor 3 for placing articles, 3b is a sprocket for driving the conveyor 3 with a chain, etc. 3c shown in FIG. 2 is a sprocket 3b. It is the conveyor drive part to rotate.

Here, the state called the boil state of the present invention will be described. Ordinary boiling (boiling) performed using a conventional boiled kettle or simmering device, soaks organic products such as small fish in hot water and heats them under atmospheric pressure to heat the internal tissues (proteins, etc.) In addition, the hot tissue is allowed to penetrate into the internal tissue and the tissue is denatured. On the other hand, in the present invention, the boiled state means that the heat of heated air at high humidity w (absolute humidity, corresponding relative humidity is wφ) and temperature T as shown in FIG. By heating, the internal tissue is heated to bring the moisture at the temperature Ti to a boiling state or a state similar to that at the outside, and at this time, through the internal ejection path formed by the ejection of the vaporized gas, etc. Humidity wi (absolute humidity, corresponding relative humidity is wiφ) is adjusted by the humidity difference (w-wi) between inside and outside, and the humidity of gas so that the tissue surface (skin etc.) does not discolor due to external heat etc. It is to suppress by. That is, the boiled state of the present invention is such that a void portion in the internal tissue is boiled with hot water by making a high-humidity high-temperature gas impinging jet of temperature T and humidity w and a turbulent gas atmosphere formed thereafter. At the same time, the temperature Tb and humidity wb (saturated absolute humidity) in the internal tissue at the same time are set to a state of temperature Ti and humidity wi, and the moisture content of the tissue itself is set to a water content state accompanying the phase change at this time. It means to protect the surface from discoloration due to heat and dehydration as well. The article boil correspondence temperature and the article boil correspondence humidity of the present invention are the temperature T and the absolute humidity w (relative humidity wφ) of the high-humidity high-temperature gas when realizing this boil state. The temperatures Tb and Ti and the humidity wb and wi are merely average expressions for explanation. The absolute humidity is kg of water vapor in a volume of 1 m ³ , and the relative humidity is a percentage ratio (%) between the amount of water vapor contained in the volume of 1 m ³ and the saturated water vapor amount at that temperature. Furthermore, the absolute humidity may be kg of water vapor contained in 1 kg of dry air in humid air.

  The temperature T corresponding to the article boil of the high-humidity high-temperature gas with the humidity w is the temperature Tb and humidity wb of the internal tissue realized by the desired boiling with the original hot water, and the temperature Ti and humidity wi when boiling with the gas of the present invention. Is a predetermined temperature rise time until the temperature rises and settles, for example, in the case of crepe fish, etc., the temperature is approximately equilibrated (Tb≈Ti, wb≈wi≈w) in 10 seconds to 120 seconds. Such high-speed heat transfer, as will be described later, repeats high-speed injection from a large number of nozzles arranged vertically at a short distance and uniformly distributed to the object being transferred. This is realized by performing injection. If high-humidity and high-temperature gas is injected from the top, bottom, left, and right directions intersecting the article in a plane perpendicular to the transfer direction across the endless net 3a of the conveyor 3, the collision flow becomes more complicated and the heat transfer time is increased. Can be shortened. In addition, since the size of rice cakes, rice cakes, vegetables, etc. increases, depending on the size, the temperature corresponding to the article boil, such as Tb≈Ti, wb≈wi≈w in a longer time, for example, 1 minute to 10 minutes, A boil-compatible humidity may be employed. The temperature rise time is specific to the target article and is determined for each article. If the time required for realizing the boiled state is long and it takes time for the temperature Tb and humidity wb of the internal tissue and the temperature Ti and humidity wi to be substantially in an equilibrium state, the relationship with the transport speed also has a relationship. However, once heated in a short time, a circuit provided separately is transported and returned to the entrance, and the necessary heating is repeated again, thereby realizing a boiled state without increasing the size of the apparatus. In addition, since it may be accompanied by a temperature fall when heating repeatedly twice or more times, the temperature rise time in this case is set long.

  In general, the heating method of “steaming” performed in cooking or the like is performed by using the heating temperature T and the humidity w (T) of the saturated water vapor that is inevitably determined by the heating temperature T. It differs from boiling in a high-temperature gas atmosphere. That is, the heating method of “steaming” cannot change the temperature Ti and the humidity wi in the internal tissue independently of each other as in the present invention, and when the temperature T is changed, the humidity w (T ) Is uniquely determined and cannot be freely adjusted. The present invention independently selects the temperature and humidity of the gas, and sets the temperature in the tissue of the article and the air gap humidity to the temperature Ti, by setting the temperature to the article boil and the humidity corresponding to the article respectively. The humidity is wi, the water content is maintained, and the surface is protected by moisture. That is, it is possible to prevent a “fluffy” state in which excess moisture remains on the surface of the article, and the subsequent drying can be performed quickly without damaging the surface.

  The boil state of the present invention is normally performed under atmospheric pressure, but this atmospheric pressure is not limited to atmospheric pressure (for example, 0.101 MPa) as an accurate numerical value. For example, in order to eject high-humidity high-temperature air, the heating chamber includes a pressurized state (for example, 0.2 MPa as an example). At 0.2 MPa, the saturation temperature is 120 ° C. In addition, the pressure in a heating chamber can be changed and the process under a predetermined pressure can be implemented by calculating | requiring the relationship between each article boil corresponding temperature and the article boil corresponding humidity at the time of atmospheric pressure and pressurization. . In the case of performing control or the like, the humidity corresponding to the article boil is more preferable because the relative humidity is easier to understand.

  Next, 4a and 4b are fans for sucking air to supply heated air to the mixing chambers 2a and 2b, 5a and 5b are heat exchangers for heating the air provided in the fans 4a and 4b, 6a, 6b is a plurality of nozzles provided in the mixing chambers 2a and 2b, and 7a and 7b are stirring devices for stirring the high-humidity high-temperature air in the mixing chambers 2a and 2b. The mixing chamber 2b is accommodated in the space in the longitudinal section of the endless conveyor 3 surrounded by the sprocket 3b. In the preparation chamber 2a, a large number of nozzles 6a are arranged vertically on a plane parallel to the conveyor 3 so that high-humidity high-temperature air can be sprayed evenly toward the upper surface of the endless net 3a. The blending chamber 2b is the same, and a large number of nozzles 6b are arranged vertically on a plane parallel to the conveyor 3 so that high-humidity high-temperature air can be sprayed evenly toward the lower surface of the endless net 3a. Articles conveyed by the conveyor 3 are uniformly sprayed with high-humidity high-temperature air from above and below the endless net 3a.

  In the case of boiling with hot water, the article is heated relatively uniformly by the surrounding hot water, but the boiled state with high-humidity high-temperature air blows out a collision jet of high-humidity high-temperature gas into the heating chamber 1 and has high humidity in a turbulent state. A high temperature gas atmosphere is required. A flow is formed in the heating chamber 1 by the injection from the nozzles 6a and 6b, which may cause uneven temperature and humidity partially. However, since the articles are conveyed by the conveyor 3, these do not occur. However, in order to realize a uniform boil state without transfer, adjustment of the temperature and humidity of the high-humidity and high-temperature air in the preparation chambers 2a and 2b, the arrangement and shape of the nozzles 6a and 6b, the injection speed, the article The distance is important.

  A boiler 8 sends high-temperature steam to the heat exchangers 5a and 5b to heat the air sucked by the fans 4a and 4b to 80 to 100 ° C, preferably 95 to 100 ° C. Similarly, the boiler 8 supplies the raw steam for humidity adjustment to the preparation chambers 2a and 2b. Reference numeral 9 denotes a drain discharge passage, and reference numeral 10 denotes a live steam chamber for preliminarily imparting humidity (moisture) to articles using live steam. Thereby, the surface of the article can be reliably protected. Further, 11 is a live steam pipe for transferring live steam from the boiler 8 to the mixing chambers 2a and 2b and the live steam chamber 10, and 12 is heat exchange for sending high-temperature steam for heat exchange from the boiler 8 to the heat exchangers 5a and 5b. Steam piping for use. 36 is an article supply section for supplying articles, and 37 is a discharge section for discharging articles after boiling. Although the conveyor 3 is provided in the heating chamber 1 and a seal is provided, the live steam chamber 10 serves as a buffer zone for leakage to the outside and stabilizes the state in the heating chamber 1.

  Next, the control configuration of the gas boil device according to the first embodiment will be described with reference to FIGS. In FIGS. 1 and 2, 13a and 13b are temperature sensors for detecting the temperature of the high-humidity hot air in the preparation chambers 2a and 2b, 13c is a temperature sensor for detecting the temperature of the high-humidity hot air in the heating chamber 1, and 13d is It is a temperature sensor that detects the temperature of raw water vapor in the raw steam chamber 10. 14a and 14b are humidity sensors for detecting the humidity of the high-humidity high-temperature air in the preparation chambers 2a and 2b, and 14c is a humidity sensor for detecting the humidity of the high-humidity high-temperature air in the heating chamber 1. 14 d is a humidity sensor that detects the humidity of the raw water vapor in the raw steam chamber 10. Reference numeral 15 denotes a first steam control valve for controlling the amount of steam supplied to the heat exchangers 5a and 5b, and 16 denotes a second steam control valve for controlling the amount of live steam.

  In FIG. 2, 18 is a control unit, 18 a is a boil temperature control unit that controls high-humidity high-temperature air to an optimum temperature for each target article, and controls the temperature of raw water vapor in the raw steam chamber 10, and 18 b is for each target article. In addition, a high humidity and high humidity air is controlled to an optimum humidity and the humidity of the raw water vapor in the raw steam chamber 10 is controlled, and a boil system control unit 18c controls the system of the gas boil device. Reference numeral 19 denotes a storage unit which stores a program which is read into a hardware central processing unit (CPU) and functions as a function realization unit constituting the control unit 18, and 19a controls a system of the gas boil device. A boil system control program storage unit 19b is an optimum temperature-humidity table storage unit in which the optimum temperature and humidity for boiling with high-humidity high-temperature air are stored for each target article.

In order to bring an article into a boiled state with the gas boil apparatus of the first embodiment, first, an input for specifying the target article is made to the control unit 18 of the gas boil apparatus. For example, a list of boiled objects is displayed, and a boiled object name is selected from the list to identify an article. The controller 18 has an optimum high-humidity high-temperature air temperature To (article boil compatible temperature), for example, To = 95 ° C. and humidity wo (article boil compatible humidity), for example, wo = 2.3 kg / m ³ ( (Relative humidity 95%) is read from the optimum temperature-humidity table storage unit 19b and set as a target value.

  Subsequently, the gas boil device starts operation of the boiler 8 by the control unit 18 and starts the fans 4a and 4b and the stirring devices 7a and 7b. The control unit 18 performs control until the temperature sensor 13c and the humidity sensor 14c indicate the target temperature To and the target humidity wo. Therefore, the control unit 18 calculates the difference between these target values and the measured temperature T of the temperature sensor 13c and the measured humidity w of the humidity sensor 14c, ΔT = T−To, Δw = w−wo, and ΔT , Δw, the differences ΔTa, ΔTb, Δwa, Δwb between the preparation chambers 2a, 2b corresponding to Δw are calculated and fed back. Based on this, the first steam control valve 15 and the second steam control valve 16 are opened and closed and controlled until the target temperature To and the target humidity wo are reached.

  The target temperature To is 80 ° C. to 100 ° C. under atmospheric pressure, preferably 95 ° C. to 100 ° C., preferably 98 ° C. to 100 ° C. to achieve a boiled state, and the target relative humidity is 80% to 100%, preferably boiled In order to obtain a state, 95% to 100% is desirable. Under this condition, the surface of the article will not be damaged, and a small organic article will be almost in the boiled state. Boiling by boiling conventionally performed involves immersing an article in hot water and heating it to transfer the heat to the internal tissue, and infiltrate the hot water into the internal tissue to denature the tissue. However, in the present invention, the article is placed in high-temperature high-temperature air at 80 ° C. to 100 ° C. and 80% to 100%, and the heat of the external high-humidity high-temperature air is transferred to the internal tissue as shown in FIG. Heat to bring the water to boiling or close to it, and adjust the humidity inside the tissue with the gas humidity through the in-tissue ejection path of the ejected gas, and leave sufficient moisture containing umami components in the tissue. The surface is prevented from being discolored by heat and dehydration. Therefore, if the external relative humidity is 80% to 100%, preferably 95% to 100% under atmospheric pressure, the boiled state can be surely equivalent to boiling the inside, and the surface can be dried or burnt. It can protect from discoloration, etc. And at this time, useful components, such as a umami component, do not lose | disappear in hot water from articles | goods, but are hold | maintained inside.

  When the inside of the heating chamber 1 reaches the target temperature To and the target humidity wo, and the temperature and humidity inside the live steam chamber 10 reach predetermined values and become stable, the control unit 18 drives the conveyor driving unit 3c. To start. When articles such as small fish, vegetables, salmon, salmon, etc. are placed on the endless net 3 a of the conveyor 3, these are preliminarily humidified and heated in the live steam chamber 10 and sent into the heating chamber 1. The inside of the heating chamber 1 is adjusted to a temperature To and humidity wo that are optimal for this article, and is conveyed while being sprayed with high-humidity high-temperature air of this temperature To and humidity wo from above and below by a number of nozzles 6a and 6b. The average conveying speed v of the conveyor 3 is the heating time θ1 per one passage through the heating chamber in which air is blown to make the inside of the article structure boiled, and the state of this heating atmosphere (boiled state at the final passage outlet). It is determined from the holding time θ2 to be maintained. Since the length L of the conveyor 3 in the heating chamber 1 is transported in time (θ1 + θ2), the average transport speed v may be L / (θ1 + θ2). Although it differs depending on the article, on average, (θ1 + θ2) is about 3 to 6 minutes, and in the case of the conveyor 3 with L = 10 m, if it is conveyed at about v = 1.7 m / min to 3.3 m / min. Good. When the time (θ1 + θ2) is large, the conveyance speed v is fixed and the number of times of conveyance in the gas boil device is increased.

  Thus, since the gas boil apparatus of Example 1 does not use hot water, useful components such as umami components are not eluted into the hot water and are merely transported by the conveyor, so many articles being transferred are extremely It can be boiled in a short time. It is low in energy efficiency to boil several tons of hot water in a boiled state, but since high-humidity high-temperature air is used, a high-efficiency gas boiling device can be obtained. It is possible to boil optimally for each target article, and it is possible to perform the boil work that has been performed empirically as in the past in a planned and rapid manner. It is possible to prevent a “blown” state in which excessive moisture remains on the surface of the article, and it is possible to dry quickly without damaging the surface.

  What has been described above is a gas boil device that uses a push-in fan to preliminarily adjust the humidity in the live steam chamber, but as shown in FIG. 4, the suction steam fan is used to omit the live steam chamber. This is preferable with a simple configuration. FIG. 4 is a main part configuration diagram of the gas boil device according to the second mode of the first embodiment of the present invention. In the gas boil device of the second embodiment, the article is directly sent into the heating chamber 1 to be boiled, and the air in the heating chamber 1 is sucked by the fans 4a and 4b to pressurize the mixing chambers 2a and 2b and circulate. Let The fans 4a and 4b are centrifugal fans and are respectively mounted on the mixing chamber 2a. The discharge port of the fan 4a is directly connected to the mixing chamber 2a directly below, but the discharge port of the fan 4b is the side surface of the mixing chambers 2a and 2b. Is connected to the lower surface side of the preparation chamber 2b. The heat exchangers 5a and 5b provided at the suction ports of the fans 4a and 4b are erotic fin heaters each having a spiral fin wound, and the air is efficiently passed through high temperature steam through the erotic fin tube. Heat with heat exchange.

  In FIG. 4, 15 a and 15 b are electromagnetic valves constituting the first water vapor control valve 15, and 16 a and 16 b are electromagnetic valves constituting the second water vapor control valve 16. The solenoid valves 15a and 15b are adjusted based on the temperatures detected by the temperature sensors 13a and 13b to control the temperature of the air. The air flow rate is adjusted by controlling the rotational speed of the fans 4a and 4b. Moreover, the humidity of the high temperature air in the preparation chambers 2a and 2b is adjusted by adjusting the electromagnetic valves 16a and 16b based on the humidity detected by the humidity sensors 14a and 14b. Since humidity adjustment is not performed preliminarily in the live steam chamber, it is also preferable to increase the humidity slightly or partially on the inlet side of the heating chamber in order to protect the article surface as much as possible. The solenoid valves 16a and 16b serve as a humidity controller for high-humidity high-temperature air in the gas boil device according to the second embodiment of the first embodiment.

  The conveyor belt of the conveyor 3 is constituted by an endless net 3a, and high-humidity high-temperature air is repeatedly ejected from a plurality of nozzles from above and below in a plane perpendicular to the transfer direction, as shown in the CC cross section of FIG. The impinging flow is complicated, and high-efficiency heat transfer can be realized during a predetermined temperature rise time. The conveyor 3 can be easily loaded and unloaded by increasing the length of the transported portion. The direction in which the flows intersect is not limited to the two upper and lower directions. In addition to the endless net 3a described above, a container provided with a mesh or the like may be supported by the conveyor 3 and transferred as in the third and fourth embodiments.

  As described above, the gas boil device according to the second embodiment of Example 1 can be configured simply by using a suction fan and omitting the live steam chamber, and is a plane perpendicular to the transfer direction. A large number of nozzles are distributed so as to intersect the article in the interior, and high-humidity high-temperature air is injected from above and below, so that the injection onto the article surface can be continued continuously. Heat transfer can be realized.

  Next, the transferred product sterilizer according to the second embodiment of the present invention will be described. The transferred object sterilization apparatus of Example 2 sterilizes an article being transferred in a gas atmosphere in a short time. The gas boil apparatus of Example 1 is to boil materials such as small fish to kill germs, but the purpose of the boil is not limited to sterilization, but rather allows drying for a long period of time by drying, This is to obtain a fresh taste of dried fish, and a configuration for that purpose. On the other hand, the sterilization by the transferred product sterilization apparatus of Example 2 does not have the purpose of preserving and tasting, and is sterilized in a short time while transferring many articles under a gas atmosphere. This is a sterilization treatment different from the boil by the gas boil device. And it is also suitable to sterilize the transferred product sterilization apparatus of Example 2 with high humidity and high temperature air.

  The configuration of the transferred material sterilization apparatus of the second embodiment is basically the same as that of the gas boil apparatus of the first embodiment, and the detailed description will be given to the first embodiment. 1 to 4 are also referred to in the transferred product sterilization apparatus of the second embodiment. However, the transferred material sterilization apparatus of Example 2 has the boil temperature control unit 18a, the boil humidity control unit 18b, the boil system control unit 18c, and the boil system control program storage unit 19a described in FIG. The temperature control unit 18a, the humidity control unit 18b for sterilization, and the system control unit 18c for sterilization are read, and the optimum temperature-humidity table storage unit 19b stores articles for each composition of articles and high-temperature gas. An optimum gas temperature (hereinafter, sterilization-compatible temperature) that can be sterilized within a predetermined temperature rise time while being transferred is stored. Furthermore, when high-humidity high-temperature gas is used as the high-temperature gas, the humidity at this temperature (hereinafter, sterilization-compatible humidity) is also stored.

  The sterilization temperature is such that the article is transported through the apparatus at least once for sterilization, and the temperature of the article is substantially in equilibrium with the hot gas within a predetermined temperature rise time by high-temperature gas injection and gas atmosphere during this period. The temperature is such that the article is sterilized by heat. The sterilization-compatible humidity is used when sterilizing with a high-humidity high-temperature gas, and is the humidity of the gas so as not to cause a humidity change in the tissue as much as possible when the vaporized gas is ejected from the inside of the article. . This sterilization-compatible humidity corresponds to the article voile-compatible humidity when the sterilization-compatible temperature is the article voile-compatible temperature of Example 1, and can contain the outflow of useful components and the internal humidity drop. It is also possible to provide a live steam chamber for supplying moisture when the temperature drops after sterilization.

  In order to be able to cope with spores such as spore bacteria and fungi in addition to general bacteria, the transferred material sterilization apparatus of Example 2 has a normal sterilization temperature of 60 ° C. to 100 ° C. Heating can be performed for several tens of minutes to several hours at a temperature of 100 ° C. to 160 ° C., preferably 100 ° C. to 200 ° C. including 120 ° C. or higher. Therefore, heating can be continued for several tens of minutes to several hours at a temperature of 60 ° C. to 200 ° C. for sterilization. In the case of Example 2, in FIG. 1, the heat exchangers 5a and 5b are capable of heating at 60 ° C. to 200 ° C., and the fans 4a and 4b are also heated within the heating chamber 1 to about 0.4 MPa to 0.6 MPa. It is preferable to use a fan, a blower, or a compressor that can pressurize up to the pressure.

  For each article, the temperature and humidity are independently selected, and even when the temperature exceeds 100 ° C., each is set at a predetermined sterilization temperature. Possible structure is adopted. The heating chamber 1 shown in FIG. 1 is a heating chamber 1 that can be pressurized because it is necessary to maintain the internal pressure. Although the sealing device which keeps the confidentiality with the outside air is required for the conveyor 3 which conveys a target object, what kind of form may be sufficient if confidentiality is maintained, such as what interrupts | blocks a sealing line using an internal pressure. It is simplest and preferable to provide the entire conveyor 3 in the heating chamber 1.

  The object to be sterilized differs depending on the type and size. For example, in a small-sized article such as a small fish of food, general bacteria may be sterilized while being transferred at 60 to 75 ° C. for 3 to 5 minutes. Chirimen miscellaneous fish and the like can be sufficiently dealt with by sterilization at 60 to 75 ° C. for at least 3 to 5 minutes. However, when the size is increased, it is desirable to extend the heating time and sterilize by increasing the heating temperature, and to heat at 80 ° C to 100 ° C, preferably 95 ° C to 100 ° C. When using a boiled state of high humidity and high temperature air, the humidity is set to 80% to 100%, preferably 95% to 100%. Moreover, with respect to heat-resistant bacteria, it is heated for a long time at a temperature of at least 100 ° C. to 120 ° C., and in some cases at 120 ° C. or higher. Since the transferred product sterilization apparatus of Example 2 uniformly distributes a large number of nozzles and injects air from above and below, it can continue the collision injection to the article surface continuously for a long time while being transferred, and has high efficiency. Since heat transfer can be realized, it can be easily sterilized, and a large amount of articles can be sterilized continuously for sterilization while being transported, which has not existed in the past. In addition, when sterilizing fish and shellfish, vegetables, meat and the like, the surface is not damaged for the same reason as described in Example 1, and useful components are not washed away.

The heating unit 30 is for heating and drying the article accommodated in the container 21, and includes a heat exchanger that uses high-temperature steam from the boiler 8. The blower 31 is for circulating the air inside the drying chamber 29.

  The drying side temperature sensor 28 detects the temperature inside the drying apparatus. The gas boil device 38 is the same as that described in the first embodiment. In the discharge unit 37, the article may be manually transferred to the container 21, or the article discharged from the conveyor 3 may be directly placed on the container 21 and placed on the belt 25c by a handling mechanism (not shown).

  6A is a perspective view of a container and a horizontal conveyance path in Embodiment 3 of the present invention, and FIG. 6B is a cross-sectional view of the container and horizontal conveyance path in Embodiment 3 of the present invention. The container 21 is the above-described salo, and is mainly composed of a storage portion 21a in which a recess for storing articles is formed. The container 21a is made of a material in which a large number of holes such as a mesh are formed so that high-humidity heated air can be ejected from the upper and lower nozzles 6a and 6b while holding an article. A bracket 21d is provided in the accommodating portion 21a, and a roller 21b is rotatably provided in the bracket 21d via a shaft portion 21c. Further, the roller 21 b is movable along the horizontal conveyance path 22. That is, the container 21 provided with the rollers 21b can be moved in the horizontal direction along the horizontal conveyance path 22 by being pushed out by the pushing portion 26.

The extruding unit 26 as the conveying unit 23 is provided in the horizontal conveying path, and includes a belt 26a wound around the driving rotating unit 26b and the driven rotating unit 26c, a motor 26d for driving the driving rotating unit 26b, and a belt. The abutting member 26e is erected on 26a and abuts on the side of the container 21. Accordingly, when the motor 26d is driven, the abutting member 26e moves to the left and right, and the abutting member 26e of the pushing portion 26 abuts the side of the container 21 to bring the container 21 into the horizontal direction by a certain distance. It pushes out (for the moving stroke of the contact member 26e). In addition, you may employ | adopt what has arrange | positioned the cylinder which has the rod which protrudes and projects sideways as an extrusion means. In this case, the tip of the rod corresponds to a contact member that contacts the side of the container 21. Note that the belt 25c of the lift portion 25 shown in FIG. 5 is configured to avoid interference with the push-out portion 26. In the case of the third embodiment, the belt 25c may be arranged to avoid interference with the push-out portion 26. Two are arranged with a gap. The two belts 25c rotate in a state of being synchronized with each other.

  The shift unit 24 is provided in the interstage conveyance path, and has a support member 24a that supports the container 21 at the tip of the rod of the cylinder 24b. Therefore, by immersing the rod of the cylinder 24b, the container 21 supported by the support member 24a can be shifted to the horizontal conveyance path 22 one step below. Further, the central portion of the support member 24a is greatly opened, and has a shape that avoids interference with the contact member 26e described above. Further, in the horizontal conveyance path 22, the upper part of the portion corresponding to the position where the shift unit 24 is provided is open. Thereby, the interference between the roller 21b (see FIG. 6) of the container 21 transferred from above and the horizontal conveyance path 22 can be avoided, and the container 21 can be smoothly shifted to the horizontal conveyance path 22 one step below. It has become. In addition, the shift part 24 is not restricted to the thing using the cylinder 24b, Various forms can be considered.

  Next, the control configuration of the drying apparatus in Embodiment 3 of the present invention will be described. The drying apparatus according to the third embodiment efficiently realizes an article drying operation under the control of a control unit including a storage unit, a CPU, and the like. FIG. 8 is a functional block diagram according to the third embodiment of the present invention. The control unit 32 reads the control program and data stored in the storage unit 33 into a CPU or the like to control the drying apparatus, and performs a transfer mechanism control unit 32a, a transfer enable / disable determination unit 32b as a function realization unit in software, and a drying unit. The side temperature control part 32c etc. are comprised. In the third embodiment, the control unit 32 includes the boil temperature control unit 18a, the boil humidity control unit 18b, and the boil system control unit 18c described in the first embodiment as function realizing means. Further, the storage unit 33 is provided with a mechanism control program storage unit 33a, a temperature control program storage unit 33b, a data storage unit 33c, etc., and a boil system control program storage unit 19a for controlling the gas boil device 38, an optimum A temperature-humidity table storage unit 19b is provided.

  The transfer mechanism control unit 32a controls the transfer mechanism unit including the transport unit 23, the shift unit 24, and the lift unit 25 based on the mechanism control program stored in the mechanism control program storage unit 33a. The information of the transfer availability determination unit 32b is used. When there is a container, the transfer possibility determination unit 32b that has obtained a signal from the container presence / absence sensor 27, which is a sensor for detecting the presence / absence of the container, such as whether or not the container already exists at the position where the container is about to be sent. It is judged that transfer is impossible, and when there is no container, it is judged that transfer is possible. Based on this determination information, the transfer mechanism unit such as the upstream transport unit 23 is operated.

  Thus, if the transfer mechanism control unit 32a controls the mechanism unit based on the determination information of the transfer enable / disable determination unit 32b, the containers interfere with each other by feeding the containers further to the position where the containers exist. It is desirable that damage to the container 21 or the transfer unit 23 can be avoided. That is, by providing the container presence / absence sensor 27 that detects the presence / absence of the container 21 at the beginning and / or end of the horizontal conveyance path 22, the container can be efficiently conveyed without forcibly interfering with each other.

  The drying side temperature control unit 32c controls the heating unit 30 and the air blowing unit 31 based on the temperature control program stored in the temperature control program storage unit 33b, and preferably uses information obtained from the temperature sensor 28 for this control. Thus, the temperature inside the drying chamber 29 is controlled with high accuracy. The data storage unit 33c stores the conveyance cycle of the container 21, the drying time of the articles accommodated in the container 21, and the like. Note that the control of the article supply unit 36 and the discharge unit 37 is also performed by the control unit 32.

  Then, operation | movement of the drying apparatus of Example 3 is demonstrated. FIG. 9A to FIG. 9I are explanatory diagrams of the transport operation in Embodiment 3 of the present invention. This transport operation is performed when the container 21 exists at the start end (upstream end in the container transport flow) and the container does not exist at the end (downstream end) in each transport path. Is to send in. Note that the heating unit 30 and the air blowing unit 31 operate while being controlled by the control unit 32 during the transport operation. First, in the state of FIG. 10 (a), the container is present at the upstream end (A part) of the uppermost stage and the container is not present at the downstream end (B part). 26 feeds the container into part B. Here, the extrusion part 26 of the A part pushes out the container in the A part, the container pushes out the adjacent container, and the pushed out container pushes out the adjacent container so that the container is fed into the B part. It has become.

  That is, the force generated by the push-out portion 26 in the horizontal conveyance path 22 is transmitted in a ball shape to another container using the container as a transmission medium. According to this configuration, the pushing unit 26 pushes out a stroke of a certain distance in the horizontal direction (stroke for one container) and sequentially pushes out the container 21 to feed the container to a position B that is more than a certain distance away. Can do. In addition, a belt conveyor etc. can also be employ | adopted as a conveyance part, without employ | adopting the extrusion part 26. FIG.

  In FIG. 9B and subsequent steps, the same operation as in FIG. 9A is performed. In FIG.9 (b), the container 21 is sent to A part by driving the lift part 25 and raising the container 21. FIG. In FIG.9 (c), the extrusion part 26 is operated and the container 21 is sent into C part. In FIG.9 (d), the container 21 is sent into D part by operating the shift part 24 and shifting the container 21 below. Thereafter, the shift unit 24 returns upward while avoiding interference with the container 21. Specifically, by projecting the rod 24d of the cylinder 24c of the shift portion 24, the support member 24a is moved out of the horizontal conveyance path 22 via the cylinder 24b connected to the rod 24d, and then the cylinder 24b is projected. After the support member 24a is positioned above the lower horizontal conveyance path 22, the rod 24d of the cylinder 24c is immersed.

  In FIG.9 (e), the extrusion part 26 is operated and the container 21 is sent in to E part. In FIG.9 (f), the container 21 is sent to F part by operating the shift part 24 and shifting the container 21 below. Thereafter, the shift unit 24 returns upward while avoiding interference with the horizontal conveyance path 22. In FIG.9 (g), the extrusion part 26 is operated and the container 21 is sent in to G part. In FIG.9 (h), the container 21 is sent into the H part by operating the shift part 24 and shifting the container 21 below. Thereafter, when the shift unit 24 returns to the upper side while avoiding interference with the container 21, FIG. 9 (i) is obtained, that is, the state of FIG. 9 (a) is restored. By repeating this, the articles contained in the container 21 are heated and dried while circulating.

  Even when the quantity of the containers 21 arranged in the horizontal direction is changed or the number of stages of the horizontal conveyance path 22 stacked in the vertical direction is changed, the articles stored in the containers 21 are circulated by performing the same operation. Heat to dry.

  As described above, the drying apparatus according to the third embodiment conveys the article raised along the ascending conveyance path along the uppermost horizontal conveyance path, and transfers the article to the horizontal conveyance path one level below the interstage conveyance path. The product is transported in the reverse direction on the horizontal transport path of the steps, and the reciprocating transport accompanied by the reversal of the transport direction in the horizontal transport unit and the transfer between the steps in the inter-stage transport path are repeated at least once. Since the container circulates along the vertical plane while keeping the level, a large amount of articles can be dried with high efficiency, and the apparatus can be made compact and automated. After the articles are boiled with the gas boil device, a large amount of articles can be uniformly dried with high efficiency, and the articles can be dried in a limited space by circulation along a vertical plane. Since the gas boil device of the present invention is used, there is no excess moisture on the surface of articles such as small fish, the articles discharged from the gas boil device will not be in a state of being swollen, and subsequent drying with a drying device is also possible It can be dried nearly 50% faster.

  Next, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 10 is a diagram for explaining the operation of the drying apparatus and the main part in Example 4 of the present invention, FIG. 11A is a fragmentary sectional view of the container and the horizontal conveyance path in Example 4 of the present invention, and FIG. FIG. 11C is a cross-sectional view of the roller transport portion of the horizontal transport path in FIG. 11A, and FIG. 12A is a cross-sectional view of the container in the fourth embodiment of the present invention. A front view and FIG.12 (b) are sectional drawings of the container of (a).

  The drying apparatus according to the fourth embodiment of the present invention has basically the same configuration as the drying apparatus according to the third embodiment with respect to conveyance, drying, control, and the like, and the article after boiling is folded in a plurality of linear paths. It is transported on the transport path and dried. That is, also in the drying apparatus according to the fourth embodiment, drying is carried out in the same manner as the operations of the third embodiment described above with reference to FIGS. 9A to 9I. An empty space is formed at one end of one of the horizontal conveyance paths of the drying conveyance path, and a plurality of containers in the horizontal conveyance path are pushed out into the shape of the empty space toward the empty space. When occupied, the shift section (second roller transport section described later) moves this container between steps (up and down). A new empty space is formed at the rear end of the row of extruded containers. Apparently, the empty space has moved from the end (front end) to the end (rear end), so that the containers The distance between the steps is one container. By repeating such an operation over the entire drying conveyance path, a large number of containers can be circulated as a force transmission medium.

  In Example 3, the transport width in which the containers are transported is shortened by one container at the right end in the upper two stages from the top of all four stages. However, in Example 4, the transport width in all stages is All are equal to the distance of five containers. In addition, the difference between the fourth embodiment and the third embodiment is that the conveyance is supported by a roller while the edge portion of the container is supported by a roller, and the conveyance unit is a chain drive, and is provided in this chain. It is a point which conveys by nail | claw and the meshing hole provided in the container. Therefore, there are many overlapping descriptions between the first and second embodiments and the fourth embodiment, and these are left to the description of the first and second embodiments and omitted in the fourth embodiment. In particular, the drying chamber 29, the heating unit 30, the air blowing unit 31, the article supply unit 36, and the like of Example 3 are not illustrated in detail in FIG. For these, reference is made to the description of the third embodiment and to FIG.

  FIG. 10 is a schematic front view of a drying apparatus according to Embodiment 3 of the present invention. In FIG. 10, reference numeral 22 denotes a horizontal conveyance path, and reference numeral 23 denotes a chain drive unit 42, 42 a (described later). The horizontal conveyance path 22 has a function of sending a container 41 (described later) from the upstream side to the downstream side. Part. Reference numeral 24 denotes a shift unit that can move up and down to lower the container 41 between steps. Reference numeral 25 denotes a lift unit that supplies the boiled container 41 to the drying chamber 29 and forms a drying conveyance path for circulating the container 41. 37 Is the discharge section, and 38 is the gas boil device described in the first embodiment. Reference numeral 41 denotes a container for storing the post-boiled article. The height is about 3 cm to 15 cm, the bottom is about vertical (50 cm to 200 cm) × horizontal (50 cm to 200 cm), and both sides with respect to the transport direction. This is a wide iron.

  Next, 42 and 42 a are chain drive units constituting the transport unit 23. The chain drive part 42a pushes the container 41 when the container 41 has been lifted by the lift part 25 and there is an empty space at the uppermost right end. For ease of illustration, in FIG. 10, the chain drive unit 42 a is described so as to engage the container 41 from above. However, like the chain drive unit 42 described below, the chain 41 engages with the container 41 on the upper surface of the chain. . However, it may be engaged from above as shown.

  Subsequently, reference numeral 44 denotes a roller transport unit that includes a roller for supporting the flange of the container 41 pushed in by the chain driving unit 42a, and supports the container 41 to advance in a ball shape. 44a is a second roller transport unit that is shorter than the roller transport unit 44 but has the same configuration and moves up and down between adjacent horizontal transport paths 22 to transfer the placed container 41 to the lower chain drive unit 42a. The second roller transport unit 44 a constitutes a main part of the shift unit 24.

  Therefore, the chain drive units 42 and 42a and the roller transport units 44 and 44a will be described with reference to FIGS. 11 (a), 11 (b), 11 (c) and FIGS. 12 (a) and 12 (b). 11 (a), 11 (b), and 11 (c), 43 is a chain that is driven by being fitted to the sprockets of the chain drive portions 42 and 42a, and 43a is a claw projecting outward from the chain. The claw 43a of the chain 43 of the fourth embodiment meshes with a meshing hole 47 of the container 41 described later, and forcibly advances the container 41. At this time, as the container 41 moves forward, the top side is supported by the roller conveyance unit 44, and the other container 41 existing in front of the container 41 is advanced in a ball shape, and the whole is advanced by one container.

  Reference numeral 45 denotes a roller provided on a support body of the roller conveying portions 44 and 44 a to support the flange of the container 41. Reference numeral 45 a denotes a roller support portion that supports the roller 45. A guide roller 46 is provided on the support of the roller conveying portions 44, 44 a and guides the side surface of the container 41, and 46 a is a guide roller support portion that supports the guide roller 46. The roller 45 is biased by a spring or the like at the center axis, and absorbs vibration when the container 41 is placed. Similarly, the central axis of the guide roller 46 is also urged to absorb rattling when the container 41 is conveyed. This enables stable feeding.

  Further, 47 shown in FIGS. 11 (b), 12 (a) and 12 (b) is a meshing hole formed in the flange of the container 41 for meshing with the claw 43a of the chain 43 and transferring it. The chain 43 is provided on both sides of the horizontal conveyance path 22 (both sides of the container 41), but the chain 43 on one side is also composed of a pair of chains arranged in parallel as shown in FIG. A claw 43a protrudes outward from the middle position of the chain in the row. When the two sprockets of the chain drive unit 42 shown in FIG. 11B are rotated in synchronization, the chain 43 advances the container 41 by the engagement of the claw 43 a and the engagement hole 47. The engagement holes 47 are formed in the flange of the container 41 at the same positions and intervals as the claws 43a are arranged, and at the same pitch as the claws 43a.

  Therefore, the cyclic operation when performing the drying process of the drying apparatus of Example 4 will be described. First, when there is an empty space at the upper right end of the uppermost stage, the container 41 is placed on the chain drive part 42a that is always driven at the upper end position of the lift part 25, and the claw 3a of the chain 43 and the engagement hole 47 are fitted. The container 41 is pushed out by the rotation of the sprocket. As a result, the front container 41 is moved forward by the chain conveyance width in the form of a ball. Thereby, in the uppermost horizontal conveyance path 22, the container 41 is pushed into the empty space on the second roller conveyance unit 44a, and a part of the container 41 is placed on the second roller conveyance unit 44a. . In addition, during the conveyance operation | movement of the container 41 demonstrated below, the heating part 30 and the ventilation part 31 are controlled and operate | moved (refer FIG. 5).

  At this time, the containers 41 in the lift portion 25 are lifted one stage at a time in order to make up for the empty space formed at the left end at the same time. As a result, an empty space is formed at the left end of the lowermost horizontal conveyance path 22 (the lowermost position of the lift portion 25). In order to fill this empty space, the lowermost container 41 is further pushed out toward the lift part 25 by the chain drive part 42. With this operation, the empty space moves to the right end of the lowermost horizontal conveyance path 22.

  In this state, the container 41 positioned at the right end of the second horizontal transport path 22 from the bottom is shifted to the lowest level by the second roller transport unit 44a. As a result, the lowest empty space rises to the right end of the second stage. In order to compensate for the empty space at the right end of the second stage, the chain drive unit 42 pushes the container 41 of the second stage to the right. As a result, the empty space moves to the position (left end side) of the second-stage chain drive unit 42.

  In this state, the container 41 on the left end side of the third stage is shifted to the second stage by the second roller transport unit 44a. For this reason, the empty space moves to the left end side of the first stage (third stage), the container 41 of the third stage horizontal conveyance path 22 is pushed out to the left end side by the third stage chain drive unit 42, and the empty space becomes Move to the right end of the third row. This makes it possible to shift the container 41 placed on the uppermost second roller transport unit 44a to the third stage.

  If it will be in this state, the 2nd roller conveyance part 44a of the uppermost step | level mentioned above will descend | fall below 1 step | paragraph with the state which mounted some containers 41. FIG. When the remaining unsupported portion of the container 41 is placed on the chain 43 of the third-stage chain drive unit 42 that is being driven, the upward claw 43a and the engagement hole 47 engage with each other, and the container 41 is on the lift unit 25 side. It is conveyed to.

  As described above, the container 41 is transported by one container along the transport path for drying by the above-described operation. Thereafter, such an operation is repeated to form an empty space at the end, and the row of containers 41 is pushed out to fill the empty space, and at the end, the container 41 is moved by using the second roller conveying portion 44a. Shift down one stage, form an empty space at the opposite end in the next stage, push out the container 41, shift the container 41 pushed into the empty space down one stage, and repeat this When the empty space in the lowermost lift unit 25 is filled, the container 41 is lifted and the above operation is repeated, whereby the articles contained in the container 41 can be heated and dried while circulating. The details of the control of these containers 41 are the same as those described in the third embodiment, and are omitted here. When drying is completed, the container 41 is discharged from the discharge unit 37.

  As described above, in the drying apparatus according to the fourth embodiment, the conveyance is supported by the roller 45 while the flange of the container is supported by the roller 45, and is shifted to the next stage by the second roller conveyance unit 44a. 42a is driven by the claw 43a of the chain 43 and the meshing hole 47 of the container 41, so that the container 41 can be transported stably and reliably without any trouble in transportation. And automation can be realized. Since the guide roller 46 holds and guides, rattling can be absorbed. Since the gas boil device of the present invention is used, there is no excess moisture on the surface of articles such as small fish, the articles discharged from the gas boil device will not be in a state of being swollen, and subsequent drying with a drying device is also possible It can be dried nearly 50% faster.

  The present invention provides a gas boil device that makes a target object such as small fish such as chirimen small fish and vegetables, salmon, salmon, etc., boiled in a short time without losing useful components such as umami ingredients, and a target object after drying as dry matter, etc. The present invention can be applied to a drying apparatus that dries quickly, and a transferred article sterilization apparatus that sterilizes many articles being transferred under a gas atmosphere in a very short time.
