(Overview of crushing solid raw materials)
The crushing of solids such as cereals and beans is used for various foods because the crushing of solids dramatically expands the applications. However, it is also well known that it is difficult to efficiently produce a uniform pulverized product and prevent deterioration of flavor. If crushing efficiency is emphasized, the particles of the crushed product will be coarse and non-uniform, and the smoothness of wheat flour, buckwheat flour, etc. will be lost, and not only will the quality of udon and buckwheat deteriorate, but extra heat will be applied during crushing. Deterioration of flavor due to oxidation is likely to occur. If extra frictional heat is applied to the crushed material during crushing, the fresh flavor of tea will be impaired and the soymilk will have a strong green odor. The old idea of slowly rotating the mortar to crush the crushed material makes a lot of sense in that it suppresses the generation of frictional heat and thus prevents deterioration of the flavor of the crushed material during processing.

The crushing method, in which the particle size of the crushed material is adjusted by the clearance between the rotating grindstone like a millstone and the fixed grindstone, has the same basic idea even if the material is changed from natural stone to ceramic or metal. is there. This is the same in both dry crushing and wet crushing. It is a typical example that crushing buckwheat seeds in buckwheat production is performed by dry method and crushing of soybean in tofu production is performed by wet method. .. Milling by the stone mill method is used in various fields, but it is carried out by adjusting the clearance between the rotary grindstone part and the fixed grindstone part so that the desired particle size can be obtained by one-step crushing regardless of whether it is dry or wet. Has been done. Further, even in a crusher made of a metal such as stainless steel, the clearance between the rotary blade and the fixed blade is designed and implemented so that the crushed product of the desired size can be obtained by one-step crushing. ..

For example, in the case of chocolate, a raw material called cacao nibs, which is a coarsely crushed roasted cacao bean, is used. When crushing at a store such as a chocolate factory, the stone mill method may be used, and the clearance between the stone mills is adjusted step by step. Grinding should be repeated multiple times with a gradual reduction in clearance until the desired smooth chocolate is obtained. The size of a single grain of cacao, which is the raw material, is relatively large and disadvantageous for clearance. That is, since cacao is gradually finely crushed, it takes time to obtain the desired particles.

For crushing cacao, wet crushing is adopted by utilizing the fact that the melting point of cacao is about 35 ° C and it becomes a liquid (paste) due to the frictional heat between the mortar and cacao nibs during crushing cacao nibs. The temperatures of cacao and mortar during crushing are determined by the circumstances and have not been controlled in the past. If the temperature is low, the cacao cannot flow in the mortar and sticks to the groove, cannot be crushed, and the load on the motor increases. On the other hand, if the temperature is too high, the cocoa may be scorched, degrading the quality of the cocoa.

FIG. 6 is a diagram showing the arrangement positions of the intake port and the exhaust port of the temperature control device shown in FIG. 3, the figure shown by reference numeral 1061 is a view seen from the upper surface, and the figure shown by reference numeral 1062 is a diagram shown by reference numeral 1062. It is an enlarged view of the main part of the figure shown in 1061.

The temperature control device according to the present embodiment includes a heat insulating container 12, a first fan (circulation fan) 17a for exhausting the air in the heat insulating container 12 to the outside, and a second fan for taking in outside air into the heat insulating container 12. (Intake fan) 17b, a switch 19 for turning on / off the first heater (heating unit) 18a and the second heater (heating unit) 18b for heating the inside of the heat insulating container 12, the first heater 18a and the second heater 18b. , 1st fan 17a, 2nd fan 17b, 1st heater 18a, 2nd heater 18b according to the detection result of the temperature sensor (temperature detection unit) 20 for detecting the temperature in the heat insulating container 12 and the temperature sensor 20. , Includes a control unit 51 that controls the drive of the switch 19. As described above, since the crushing unit 11 is removable from the crushing device 1, the first fan 17a, the second fan 17b, the first heater 18a, and the second heater 18b are provided in addition to the crushing unit 11. Has been done.

The heat insulating container 12 is a substantially cylindrical container that houses the crushing unit 11 inside, and forms a space around the housed crushing unit 11. By warming or cooling the air existing in this space, the temperature in the space is maintained at a predetermined temperature. The details of this predetermined temperature will be described later. Although the cylindrical portion of the heat insulating container 12 is made of glass, it is not limited to glass.

Note that when the cylindrical portion of the heat insulating container 12 is made of glass, there are the following merits. That is, the crushing unit 11 can be attached to and detached from the heat insulating container, and it can be confirmed through the glass whether the crushing unit is fitted in the correct position (front and back, up and down) in the heat insulating container. Further, since it can be confirmed at a glance whether or not the crushing unit 11 is set in the crushing device 1, the hopper 13 is attached in a state where the crushing unit 11 is forgotten to be inserted, and the stopper (shutter) of the hopper 13 is mistakenly inserted. If it is turned, it is possible to prevent the cacao nibs from spilling into the heat insulating container 12.

In addition, it is possible to visually confirm the presence or absence of an error such as leakage of cocoa mass from the crushing unit 11, and it is possible to improve the visibility when cleaning the inside of the heat insulating container 12.

The first fan 17a is composed of, for example, a propeller fan, and is arranged so as to face diagonally downward (inside the heat insulating container 12) on the upper surface 12a of the heat insulating container 12 as shown in FIG. 5, and exhausts the air inside to the outside. It functions as an exhaust fan.

On the other hand, the second fan 17b is made of, for example, a sirocco fan, is provided at a position facing the first fan 17a on the upper surface 12a of the heat insulating container 12, and sucks outside air from the outside of the heat insulating container 12 to suck the outside air from the heat insulating container 12. Discharge inside. When the outside air is discharged from the second fan 17b, the temperature of the air in the heat insulating container 12 is lowered. That is, the second fan 17b functions as a cooling fan.

As described above, the heat insulating container 12 drives the first fan 17a and the second fan 17b to take in air from the outside of the heat insulating container 12 and exhaust the air to the outside to reduce the temperature of the air in the heat insulating container 12. It is designed to be kept at a predetermined temperature. In order to realize the intake and exhaust of the heat insulating container 12, the crushing device 1 is provided with a substantially disk-shaped intake / exhaust member 113 that surrounds the periphery of the introduction portion 13a of the hopper 13.

As shown in FIG. 6, the intake / exhaust member 113 has a plurality of slits 113a formed concentrically, and the exhaust port 114 and the intake port 115 are formed by a plurality of continuous slits 113a. Here, the number of slits 113a used by the exhaust port 114 is larger than the number of slits 113a used by the intake port 115.

As shown in FIG. 6, the intake / exhaust member 113 is formed of a substantially disk-shaped member, and a plurality of slits 113a notched in a rectangular shape from the center to the outside are arranged concentrically. A part of these slits 113a is used to form an exhaust port 114 and an intake port 115. That is, the exhaust port 114 and the intake port 115 are formed by a plurality of continuous slits 113a.

The exhaust port 114 exhausts the air in the heat insulating container 12 to the outside. Since the intake / exhaust member 113 is provided between the hopper 13 and the heat insulating container 12, the exhaust port 114 is provided at the upper part of the heat insulating container 12.

On the other hand, the intake port 115 takes in air into the heat insulating container 12. A second fan 17b for intake air is provided in the vicinity of the intake port 115, and by driving the second fan 17b, outside air can be positively introduced from the intake port 115 and discharged to the heat insulating container 12. it can. As a result, the heat insulating container 12 discharges the air inside to the outside and takes in the air from the outside. That is, in the present embodiment, the air is actively taken in and out of the heat insulating container 12.

The following is a supplement to the temperature raising and cooling functions of the heat insulating container 12.

When the temperature rises, the first heater 18a is installed in front of the first fan 17a, and by driving the first fan 17a, the air (warm air) warmed by the first heater 18a is kept warm. It is possible to send out to the inside of the container 12 to heat the entire inside of the heat insulating container 12. The air generated by the rotation of the first fan 17a passes through the spaces provided on the left and right sides of the first fan 17a (the front side and the back side of the paper surface in FIG. 5), and the warm air is circulated in the heat insulating container 12. Therefore, the inside of the heat insulating container 12 can be efficiently heated.

On the other hand, during cooling, the air in the heat insulating container 12 warmed by the chimney effect is exhausted above the exhaust port 114. At this time, exhaust and cooling can be promoted by turning on the first fan 17a and turning off the first heater 18a, and by using the second fan 17b (cooling fan), the outside air is taken in from the intake port 115 for efficiency. The inside of the heat insulating container 12 can be cooled well.

In the vicinity of the second fan 17b (below the heat insulating container 12), a copper discharge pipe 40 for discharging the air taken in by the second fan 17b toward the bottom of the heat insulating container 12 is provided. .. The discharge pipe 40 is arranged so as to discharge air toward the second heater 18b (heating portion) on the bottom surface (lower part) of the heat insulating container 12. That is, the discharge pipe 40 blows out the air taken in by the second fan 17b toward the conical mortar and the flat mortar of the crushing unit 11. As a result, the conical mortar and the flat mortar are prevented from becoming too hot, and the air warmed by the second heater 18b is pushed out by the air discharged from the exhaust pipe 40 to reach the top surface of the heat insulating container 12. It moves toward the exhaust port 114 of the provided intake / exhaust member 113. By driving the second fan 17b in this way, the air taken in from the intake port 115 of the intake / exhaust member 113 is discharged from the discharge pipe 40, circulates inside the heat insulating container 112, and is circulated in the exhaust port 114. Is discharged from.

As described above, the number of slits 113a used by the exhaust port 114 of the intake / exhaust member 113 is larger than the number of slits 113a used by the intake port 115. This is because the intake port 115 can be positively taken in by the second fan 17b, but the exhaust port 114 is not provided with an exhaust fan and cannot be forcibly exhausted. Therefore, many slits 113a are used. This is because the air is naturally exhausted.

The temperature control (temperature control) of the air in the heat insulating container 12 having the above configuration will be described below.

(Temperature control)
FIG. 7 is a block diagram of a control unit that controls a temperature control device included in the crushing device 1 shown in FIG.

The control unit 51 drives the first fan 17a, the second fan 17b, the first heater 18a, the second heater 18b, and the switch 19 so as to maintain the temperature inside the heat insulating container 12 detected by the temperature sensor 20 at a predetermined temperature. To control. Here, the predetermined temperature is a temperature at which the cacao beans to be crushed can be optimally crushed and the crushed cacao bean powder does not stick.

Specifically, the control unit 52 controls the drive of the first heater 18a and the second heater 18b so as to maintain the temperature inside the heat insulating container 12 detected by the temperature sensor 20 at a predetermined temperature, and the first fan. It controls the drive of the 17a and the second fan 17b.

The temperature inside the heat insulating container 12 can be maintained at a predetermined temperature only by driving control of the first heater 18a and the second heater 18b. Further, by adding the drive control of the first fan 17a and the second fan 17b, the temperature inside the heat insulating container 12 can be quickly and stably maintained at a predetermined temperature.

In particular, by controlling the drive of the second fan 17b, it is possible to positively introduce outside air from the intake port 115 of the heat insulating container 12, and it is possible to quickly cool the overheated air in the heat insulating container 12. It will be possible. This makes it possible to stably maintain the air in the heat insulating container 12 at a predetermined temperature.

(Discharge section 10)
FIG. 8 is a schematic cross-sectional view of the crushing apparatus 1 shown in FIG. FIG. 9 is a schematic cross-sectional division view of the crushing apparatus 1 shown in FIG.

As shown in FIG. 8, the discharge unit 10 is orthogonal to the drive shaft (drive shaft for turning the mortar (not shown) in the crushing unit 11) X of the drive unit of the crushing unit 11 with respect to the heat insulating container 12. It is removable in the Y direction of the arrow (horizontal to the installation surface). That is, the discharge unit 10 is detachable in the horizontal direction with respect to the heat insulating container 12. As a result, when the discharge unit 10 is mounted on the heat insulating container 12, it is not necessary to provide a member for supporting the discharge unit 10 in the vertical direction, so that the configuration can be simplified.

Further, simply by attaching the discharge unit 10 to the heat insulating container 12, the discharge path 10a of the discharge unit 10 and the discharge path 35 for discharging the crushed cocoa mass by the crushing unit 11 can be easily communicated with each other.

Further, since the second heater 18b is provided in the vicinity of the discharge path 10a of the discharge unit 10 and the discharge path 35 for discharging the crushed cocoa mass by the crushing unit 11, the second heater 18b is provided by warming the communicated discharge path. It is possible to prevent the cocoa mass from sticking and clogging in the discharge route.

As shown in FIG. 9, the discharge unit 10 rotates the cacao mass take-out lever 15 with respect to the main body of the discharge unit 10 in the direction of the arrow (direction opposite to the discharge path 10a) about the rotation shaft 15a. It has become. On the side of the cocoa mass take-out lever 15 opposite to the lever portion 15b, a switching member 15c for switching the discharge path 10a of the discharge portion 10 and the take-out port 16 between a communicating state and a non-communication state is provided.

The switching member 15c is provided so as to be movable through a through hole 10b formed in a direction orthogonal to the take-out port 16 in the discharge portion 10, and when the cocoa mass take-out lever 15 rotates in the arrow direction, the switching member 15c is provided with a through hole. The 10b is moved to the heat insulating container 12 side, and the discharge path 10a and the take-out port 16 are in a communicating state. At this time, the tip of the switching member 15c (the end on the heat insulating container 12 side) presses the crushing switch 22 provided at the lower part of the heat insulating container 12.

Therefore, by rotating the cocoa mass take-out lever 15 (operating so as to push down the cocoa mass take-out lever 15), the crushing switch 22 is pressed to start crushing, and the crushed material can be discharged from the take-out port 16. Can be in a good state. That is, since the crushing and the delivery of the crushed material are linked by rotating the cocoa mass take-out lever 15 so as to push it down, the crushing switch 22 is kept pressed by continuing to push down the cocoa mass take-out lever 15. , The crushed paste will be sent out one after another.

By the way, if the crushing device 1 is continuously used, the temperature of the crushing unit 11 rises, and as a result, the temperature of each part of the entire crushing device 1 rises. However, when the crushing device 1 is used again after the crushing device 1 has cooled sufficiently, the cocoa mass discharge path is not sufficiently warmed, so that the cocoa mass may stick in the discharge path and become clogged. Therefore, if the temperature in the discharge path does not exceed a predetermined temperature, it is preferable to control so that the crushing device 1 does not start crushing even if the cocoa mass take-out lever 15 is pushed down. In the second embodiment below, an example of controlling the start of crushing of the crushing device 1 according to the temperature in the discharge path will be described.

[Embodiment 2]

Controls the drive of the switch 22.

Specifically, the control unit 52 drives the first heater 18a and the second heater 18b if the temperature detected by the temperature sensor 21 is not equal to or higher than a predetermined temperature, but even if the crushing switch 22 is turned on, the motor 14 is controlled so as not to be driven. That is, the control unit 52 controls so that the crushing device 1 is not crushed unless the temperature of the discharge path of the cocoa mass in the heat insulating container 12 is equal to or higher than a predetermined temperature. Here, the predetermined temperature is a temperature at which the cacao beans to be crushed can be optimally crushed and the crushed cacao bean powder (cocoa mass) does not adhere.

Therefore, if the discharge path is above a predetermined temperature, the cocoa mass will not stick in the discharge path and will not be clogged.
