Abstract

The present invention relates to a high-speed fermentation drying apparatus that can process the contents by heating and mixing operation in a state in which various perishable organic substances are introduced into the contents.

In the conventional case, there is a problem in that the odor generated during drying and fermentation of contents is discharged to the outside in a state in which it is not properly removed or purified, and contaminates the surrounding environment. B. There is an unfavorable disadvantage in the fermentation action, the efficiency is low due to the internal agitation operation due to structural defects, and the end effect of the fermentation and drying is also low, making it difficult to put to practical use.

In order to solve this problem, the present invention provides a closed circulation mechanism in which hot and humid air generated by heating and mixing is performed from the inside of the main body which becomes the fermentation and drying of the contents in the form of the perishable organic substance. Moisture is separated and discharged in the form of condensate during the process, and the low-temperature and low-air air from which the moisture is removed is converted to a high-temperature-humid state during the preheating process and then fed back into the body. It is characterized by fermentation and drying at high speed without leakage and improvement of structure to improve stirring mixing effect.

Description

A High Speed Fermenting and Drying Apparatus

The present invention is a variety of organic perishables, such as food waste, vegetable by-products of the market, slaughter by-products, by-products of seafood, etc. The heating and mixing operation is carried out while the contents are put into the contents, and the hot and humid air generated from the contents inside is forced to the outside and the condensate is discharged to the outside during the circulation feeding in a sealed state, and the moisture is removed and the air is preheated. The present invention relates to a high-speed fermentation and drying apparatus for concentrating contents and fermenting and drying at high speed so that feed, compost, or fuelization can be performed while repetitive circular operation is performed.

In the conventional case, the contents are heated to be discharged to the outside after the deodorization tower is purged in the process of discharging the high temperature and high humidity internal air generated during drying and fermentation to the outside of the apparatus. The deodorizing effect persists, but as the operating time elapses, the efficiency decreases rapidly, and there is a problem of polluting the surrounding environment by being discharged to the outside in a state where the odor is not properly removed or purified from the deodorizing tower.

Of course, if the deodorizing material inside the deodorizing tower is replaced at that time, the deodorizing action can be continuously carried out to some extent, but this replacement work for maintenance is not only time-consuming and costly, but also operates during the replacement work. Since the operation rate for the device is lowered because it must be stopped, the reality is that it impedes a lot of practical operation conditions.

In addition, the internal air is discharged to the outside as described above, but the external air in the state that contains moisture as much as it is discharged and the temperature difference is relatively large is introduced as it is, which is not very desirable for drying or fermentation. Although ultimately drying occurs by removing moisture from the contents of the device, it is difficult to dry the contents under the humidity contained in the external air flowing into the interior. Inevitably, even after the treatment is performed, the quality of the contents is uneven and greatly deteriorates in quality.

In addition, in the case of the stirring blades installed inside the apparatus, due to structural defects, most of the contents are entangled on the inner wall of the apparatus during the stirring operation, so that stirring mixing is not smooth and the weight of the stirring blade is gradually increased, and the internal stirring is performed. In operation, its efficiency is low, and eventually, the effect of fermentation and drying is low, which makes it difficult to use.

The present invention has been made in order to solve this conventional problem.

The main purpose of the present invention is not to discharge the hot and humid air generated by heating and mixing from the inside of the main body that is fermented and dried in the form of injected perishable organic substance to the outside, but to remove moisture in a closed circulation state. It is fed to the inside of the device again to fundamentally block the possibility of odors, so that the problem of odors during operation can be solved to prevent contamination of outside air, and it can be dried quickly and smoothly in a short time without additional additives. And to allow for the fermentation process to take place.

Another object of the present invention is to remove the condensate by cooling to remove moisture from the hot and humid air generated inside the device and discharged to the outside of the device or the low temperature of the water is removed while the process of discharging such condensate Significantly improved the structure of the heat exchanger and condenser used in the process of converting low humidity air into high temperature and low humidity state and then preheating it to the inside of the device. To improve.

Another object of the present invention is to improve the structure of the stirring blades to be rotated in the interior of the main body in a spiral form different from each other in the inner and outer double form so that the circulation movement of the contents are continuously made In order to improve the mixing and stirring transfer effect to achieve a faster stirring operation even at low speed rotation operation.

Reference numeral 34 denotes a tank for the recovery and replenishment of the heating medium, 52 a drive motor, and 54 a drive transmission mechanism such as a chain.

In the case of the present invention made as described above is made as follows.

First, the contents of perishable organic matter to be treated through the inlet (2), for example, various kinds of food waste, slaughtered by-product organic matter discarded at the slaughterhouse, agricultural and marine by-products, and dehydrated cakes generated during the treatment of wastewater or dirt. A certain amount is introduced into (1), the inlet 2 is closed to maintain a closed state, and then the external heating source 3 is heated to heat the inside of the main body 1.

When the stirring blade 4 is gradually rotated by the driving motor 52 and the power transmission mechanism 54 while the inside of the main body 1 is heated, the central shaft 40 and the fixing member 42 are rotated. The stirring blades 44 and 46 fixedly installed at) are also slowly mixed and mixed with the contents, but the contents are circulated inside the main body 1 because the stirring blades 44 and 46 are configured in opposite directions in different spiral directions. At the same time as the feeding takes place, stirring mixing takes place as illustrated in FIG. 6.

As described above, when stirring and mixing are continuously performed while the contents located inside the main body 1 are heated, steam is generated while water is evaporated from the contents inside the main body 1, and a forced supply mechanism ( 7) to operate the closed circulation mechanism (8), the hot and humid air generated in the interior of the main body 1 is passed through the condenser 9 first through the filter (6).

As shown in FIG. 4, the hot and humid air introduced into the condenser 9 passes through the passage 108 formed in the upper finishing plate 112, the space 100, the passage 104a, the space 102, Of the corrugated pipe 122 wrapped around the outside of the inner cylinder 104 while moving through the passage 116, the space 128, the passage 104b, the space 130, and the passage 13 of the intermediate diaphragm 118. Due to the rapid endothermic action of the cooling medium passing through the inside, the cooling condensation is made and the moisture contained in the air in the high temperature and high humidity state is changed into the condensed water form and is formed by the inner and outer cylinders 104 and 106. , 102, 128 are condensed and dropped into the interior, and are finally discharged to the outside through the drain 15, and the low-temperature and low-humidity state in which water is removed from the condenser 9 is discharged to the outside to open the forced supply mechanism 7. After the feed is made to the next heat exchanger (10).

At this time, the cooling medium is fed from the tank 152 and is changed into a cold state while passing through the cooling tower 154, and the cooling medium which is changed in this way is fed into the corrugated pipe 122 installed inside the condenser 9. This is done, but through the outlet 12 of the cooling medium located at the inlet side 11 of the air from the inlet 14 located at the air outlet side 13, the heat exchange is more active in the overall path and condensation effect is achieved It is possible to improve more, the cooling medium which is raised in temperature during the condensation process is fed to the inside of the tank 152 again, and then repeatedly performs the cooling condensation process as described above.

Next, as shown in FIG. 5, the low temperature and low humidity air introduced into the heat exchanger 10 passes through the passage 208 formed in the upper finishing plate 212, and the space 200, the passage 204a, and the space ( 202, the corrugated pipe wrapped around the outside of the inner cylinder 204 while moving through the passage 216, the space 228, the passage 204b, the space 230, and the passage 23 of the intermediate diaphragm 218 ( The heating is performed by the rapid heating action of the heating medium passing through the inside of the 222, and the air in the low temperature and low humidity state is changed into the high temperature and low humidity state and is discharged to the outside through the passage 210 and thus heated. The air of the state is fed to the inside of the main body (1).

At this time, the heating medium is fed from the tank 34 to the boiler 30 and sufficiently heated in the boiler 30 and then fed to the heating unit 32 to heat the interior of the body 1 to the contents. After the basic heating operation to make the heating is carried out is fed to the heat exchanger 10, the heating medium is fed to the corrugated pipe 222 installed inside the heat exchanger 10, the air outlet side Through the outlet 22 of the heating medium located at the inlet side 21 of the air from the inlet 24 located at (23), the heat exchange can be more actively performed on the path as a whole, and the effect can be further improved. As such, the heating medium whose temperature is lowered through the heat exchange process is fed to the inside of the tank 34 again, and then the heating of the main body 1 and the ball passing through the heat exchanger 10 as described above. Of the heating process is performed repeatedly.

As described above, the hot and humid air generated inside the main body 1 is repeatedly fed to the main body 1 via the condenser 9, the forced supply mechanism 7, and the heat exchanger 10. ) The contents inside the fermentation and drying are to be made continuously, but the moisture is removed from the condenser (9) as the low-temperature and low-humidity state is not fed to the inside of the main body (1) as it is, once the heat exchanger ( 10) After the change in the state of high temperature and low humidity, the feeding is made to the inside of the main body 1, so that mixing into the high temperature and humid air that has already been generated from the contents inside the main body 1 occurs. Although the mixing is made in a situation where only a difference in humidity exists while the temperature difference between each other is small, continuous fermentation and drying operation are possible without causing thermal shock to the internal state of the main body 1. And it will have the effect that thereby maximize its efficiency.

As described above, according to the device of the present invention, the hot and humid air generated while heating and mixing is performed from the inside of the main body 1, which becomes the fermentation and drying of the contents in the form of the perishable organic substance, is not immediately discharged to the outside. After removing moisture in the closed circulation state, it is fed back to the inside of the device to fundamentally block the possibility of odors, which can solve the problem of odors during operation to prevent contamination of the outside air, and without additional additives The drying and fermentation process is quicker and smoother within a short time, and the process of discharging condensate by cooling and condensing to remove moisture from the hot and humid air generated inside the main body 1 and discharged to the outside. During the process of draining condensate Significantly improved the structure of the condenser 9 and the heat exchanger 10 used in the preheating process after converting the air into a high temperature and low humidity state and then feeding it back to the inside of the apparatus to further improve fermentation and drying efficiency. As a result, the processed by-products can be recycled with energy savings.
