(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.

As described above, the crushing unit 11 having the above configuration is detachably housed in the heat insulating container 12. The heat insulating container 12 maintains the conical mortar 27 and the flat mortar 28 constituting the housed crushing unit 11 at a predetermined temperature. The details of the temperature control device provided with the heat insulating container 12 will be described below.

(Temperature control device)
FIG. 11 is a block diagram of a control unit that controls a temperature control device included in the crushing device 1 shown in FIG. FIG. 12 is a diagram showing a schematic configuration of a temperature control device included in the crushing device 1 shown in FIG. FIG. 13 is a diagram showing the arrangement positions of the intake port and the exhaust port of the temperature control device shown in FIG. 5, the figure shown by reference numeral 1131 is a view seen from the upper surface, and the figure shown by reference numeral 1132 is a reference numeral. It is an enlarged view of the main part of the figure shown in 1131.

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 accidentally turned. If this happens, 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, 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. 12, 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. 13, the intake / exhaust member 113 has a plurality of slits 113a formed on concentric circles, 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. 13, 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 and 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 the air taken in by the second fan 17b toward the conical mortar 27 and the flat mortar 28 of the crushing unit 11. As a result, the conical mortar 27 and the flat mortar 28 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, so that the ceiling of the heat insulating container 12 is reached. It moves toward the exhaust port 114 of the intake / exhaust member 113 provided on the surface. 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)
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 (cocoa mass) does not adhere.

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.

Normally, when the crushing device 1 is continuously operated, the temperatures of the conical mortar 27 and the flat mortar 28 of the crushing unit 11 rise due to friction, and become higher than the predetermined temperature (30 ° C to 40 ° C). If the temperature rises too high, the oil will bleed too much on the surface of the cacao nibs, and the cacao nibs will stick to each other and become fooled, and clogging will easily occur at the inlets of the conical mortar 27 and the flat mortar 28. In this case, the temperature of the air in the heat insulating container 12 is lowered by driving the second fan 17b to introduce the outside air from the intake port 115, and the temperatures of the conical mortar 27 and the flat mortar 28 of the crushing unit 11 are lowered. As a result, it is possible to solve the problem caused by the temperature being higher than the predetermined temperature (30 ° C. to 40 ° C.) (cacao nibs stick to each other and become fooled).

The control unit 51 not only controls the drive of the second fan 17b according to the temperature detected by the temperature sensor 20, but also controls the drive of the first heater 18a, the second heater 18b, and the first fan 17a. It is possible to control the heating and cooling of the air inside.

For example, when the crushing device 1 is started to be used at the beginning of the day, the temperature of the entire device is low at the beginning of use, so the first heater 18a and the second heater 18b are turned on in order to raise the temperature. After that, when the crushing device 1 is continued to be used, the temperature of the conical mortar 27 and the flat mortar 28 of the crushing unit 11 rises due to frictional heat. When the temperatures of the conical mortar 27 and the flat mortar 28 rise too much, the second fan 17b that functions as a cooling fan is turned to introduce outside air into the heat insulating container 12 to lower the temperature of the air, and the conical mortar 27 and the flat mortar 28 are lowered. To cool.

Once crushed with the conical mortar 27 and the flat mortar 28 of the crushing unit 11, cocoa mass (muddy) remains in the conical mortar 27 and the flat mortar 28. When the temperature of this powder becomes lower than the melting point of the oil constituting the cacao beans, the cacao powder is solidified in the conical mortar 27 and the flat mortar 28. Therefore, the crushing device 2 does not work. Therefore, the crushing device 2 turns on the first heater 18a and the second heater 18b even when it is not in operation, and maintains the conical mortar 27 and the flat mortar 28 at a certain temperature.

(effect)
According to the crushing system having the above configuration, the hopper 13 containing the solid raw material is exposed from the upper surface of the top surface portion 201a of the mounting table 201, and the discharge portion 10 for discharging the pulverized material is exposed from the lower surface of the top surface portion 201a. Since the crushing device 1 is suspended from the mounting table 201, the state from when the solid raw material is put into the crushing device 1 until the crushed product obtained by crushing the solid raw material is discharged is described. It can be confirmed on both sides of the side that operates the crushing device 1 and the opposite side (customer side) via the stand 201.

Moreover, since there are two crushing devices 1 suspended from the mounting table 201, different types of solid raw materials can be crushed by each crushing device 1. Thereby, different kinds of pulverized products of solid raw materials can be obtained from the two pulverizers 1. For example, when cacao nibs are used as a solid raw material, they can be separated according to the type of cacao and can be divided according to the degree of roasting of cacao. Therefore, as in the crushing system 101 of the present embodiment, two crushing devices 1 are used. If so, two types of cacao mass (crushed product) can be obtained.

In the crushing system 101 of the present embodiment, as the crushing device 1 to be mounted, as shown in FIG. 5, the temperature of the air in the heat insulating container 12 is adjusted by taking in air from the outside of the heat insulating container 12 and exhausting it to the outside. A crushing device that keeps the temperature at a predetermined temperature is used, but the crushing device 2 is not limited to this, and as shown in FIG. 14, the crushing device 2 is internally circulated to keep the temperature of the air in the heat insulating container at a predetermined temperature. You may.

The temperature control device included in the crusher 2 is almost the same as the temperature control device included in the crusher 1 shown in FIG. 5, but the first fan 17a functions as a circulation fan for circulating the air in the heat insulation container 12. The difference is that the third fan 17c functions as a cooling fan.

That is, the first fan 17a is composed of, for example, a propeller fan, and as indicated by reference numeral 1151 in FIG. 15, the intake side is obliquely upward (outside the heat insulating container 112) and the exhaust side is obliquely downward (heat insulating container) on the upper surface 12a of the heat insulating container 112. It is arranged so as to face the inside of the heat insulating container 112), and is driven so that air is taken in from the inside of the heat insulating container 112 and exhausted into the heat insulating container 112 again. Specifically, when the first fan 17a is driven, the air in the heat insulating container 112 turns to the intake side through the gaps on both sides of the first fan 17a and is sucked in, and again on the exhaust side of the first fan 17a. Is discharged into the heat insulating container 112. As a result, the air warmed by the first heater 18a and the second heater 18b is circulated in the heat insulating container 112, and the air existing in the space of the portion surrounded by the glass in the heat insulating container 112 is warmed. That is, by using the first fan 17a, the air in the heat insulating container 112 is positively circulated, and the air in the heat insulating container 112 can be heated to a predetermined temperature more quickly.

On the other hand, the third fan 17c is made of, for example, a sirocco fan, is provided at a position facing the first fan 17a on the upper surface 112a of the heat insulating container 112, and sucks outside air from the outside of the heat insulating container 112 to suck the outside air from the outside of the heat insulating container 112. Discharge inside. When the outside air is discharged from the third fan 17c, the temperature of the air in the heat insulating container 112 is lowered.

The third fan 17c is driven when the temperature inside the heat insulating container 112 becomes too high due to the circulation of air inside the heat insulating container 112 by the first fan 17a, and the temperature inside the heat insulating container 112 is lowered. For example, when the temperature inside the heat insulating container 112 detected by the temperature sensor 20 becomes higher than the predetermined temperature, the third fan 17c is driven to cool the inside of the heat insulating container 112. As a result, the temperature of the air in the heat insulating container 112 is kept constant.

(Temperature control)
The control unit 52 drives the first fan 17a, the third fan 17c, the first heater 18a, the second heater 18b, and the switch 19 so as to maintain the temperature inside the heat insulating container 112 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 adhere. For example, the first fan 17a, the first fan 17a, so that the temperature of the conical mortar 27 and the flat mortar 28 in the crushing unit 11 becomes 30 ° C. to 40 ° C., which is the melting point of the oil constituting the cacao beans (melting point of the solid raw material). The drive of the three fans 17c, the first heater 18a, the second heater 18b, and the switch 19 is controlled to warm the air in the heat insulating container 112.

It is not necessary to drive and control all of the first fan 17a, the third fan 17c, the first heater 18a, the second heater 18b, and the switch 19 in order to bring the temperature to a predetermined temperature, and the first heater 18a and the second heater 18b Only on / off of may be driven and controlled. 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 112 detected by the temperature sensor 20 at a predetermined temperature. In this case, the temperature inside the heat insulating container 112 is maintained at a predetermined temperature by the operation of the first heater 18a and the second heater 18b. That is, when the temperature inside the heat insulating container 112 reaches a predetermined temperature, the first heater 18a and the second heater 18b are turned off. The predetermined temperature maintained in the heat insulating container 112 may be at least a temperature equal to or higher than the melting point of the solid raw material.

Further, the temperature sensor 20 preferably directly detects the temperatures of the conical mortar 27 and the flat mortar 28 of the crushing unit 11, but since the crushing unit 11 is detachable from the heat insulating container 112, it is provided on the heat insulating container 112 side. I have no choice. Therefore, the temperature of the conical mortar 27 and the flat mortar 28 of the crushing unit 11 is indirectly detected by detecting the temperature of the air in the heat insulating container 112.

As described above, 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 third fan 17c, the temperature inside the heat insulating container 112 can be quickly and stably maintained at a predetermined temperature.
