(Overview of grinding solid raw materials)
Grinding of solids such as grains and beans is used for various foods because the uses of the solids are dramatically expanded by grinding them. However, it is well known that it is difficult to grind uniformly efficiently and prevent deterioration of flavor. If grinding efficiency is emphasized, the particles of the ground material will become coarse and uneven, and wheat flour, buckwheat flour, etc. will lose smoothness, and not only will the quality of udon and buckwheat decrease, but the flavor will easily deteriorate due to oxidation due to the excess heat applied during grinding. If excess frictional heat is applied to the ground material during grinding, the fresh flavor of tea will be lost, and soy milk will have a strong grassy smell. The old idea of grinding the ground material by slowly rotating the mortar is extremely reasonable in that it prevents the flavor of the ground material from deteriorating during processing because it suppresses the generation of frictional heat.

The grinding method, in which the particle size of the ground material is adjusted by the clearance between a rotating grindstone and a fixed grindstone, as in a millstone, remains the same even if the material changes from natural stone to ceramic or metal. This is true for both dry and wet grinding, with the typical examples being the dry grinding of buckwheat seeds in soba production and the wet grinding of soybeans in tofu production. Millstone grinding is used in a variety of fields, but whether dry or wet, the clearance between the rotating grindstone and the fixed grindstone is adjusted so that the desired particle size is achieved in one grinding stage. Even in grinders made of metal such as stainless steel, the clearance between the rotating blade and the fixed blade is designed and implemented to achieve the desired size in one grinding stage.

For example, in the case of chocolate, the raw material used is coarsely ground roasted cocoa beans called cocoa nibs. When grinding in a store such as a chocolate factory, a millstone method may be used, and the clearance between the millstones is adjusted in stages. The grinding process must be repeated multiple times while gradually narrowing the clearance until the desired smooth chocolate is obtained. This is a disadvantage because the size of a single grain of cocoa, the raw material, is relatively large compared to the clearance. In other words, the cocoa is gradually ground finely, so it takes time to produce the desired particles.

Wet grinding is used to grind cacao, taking advantage of the fact that cacao has a melting point of around 35°C and turns into a liquid (paste) due to the heat of friction between the mortar and the cacao nibs when grinding. The temperature of the cacao and mortar during grinding is determined by the natural course of events and has not traditionally been controlled. If the temperature is low, the cacao cannot flow in the mortar and sticks to the grooves, making it impossible to grind and increasing the load on the motor. On the other hand, if the temperature is too high, the cacao may burn, reducing the quality of the cacao.

(Overview of the grinding system)
Fig. 1 is a front view of the grinding system according to the present embodiment, and Fig. 2 is a schematic cross-sectional view of the main part of the grinding system shown in Fig. 1.

As shown in FIG. 1, the grinding system 101 includes two grinding devices 1 and a mounting table 201 on which the grinding devices 1 are mounted.

The mounting table 201 includes a top surface 201a from which the crushing device 1 is suspended and columnar portions 201b that support the top surface 201a at both ends, with the top surface 201a and the columnar portions 201b on both sides forming an arch.

In the grinding system 101, two grinding devices 1 are fixed to the mounting table 201 so that a hopper 13 that stores the solid raw material to be ground is exposed from the upper surface of the top surface 201a of the mounting table 201, and a thermal insulation container 12, a motor 14, and a discharge unit 10 are exposed from the lower surface of the top surface 201a. In other words, in the grinding system 101, the two grinding devices 1 are fixed in a suspended state to the mounting table 201.

Specifically, as shown in FIG. 2, an insulated container 12, which is one of the components of the grinding device 1, is fixed by a plurality of screws 401 within the top surface 201a of the mounting table 201.

In addition, a control board 301 for driving and controlling the crushing device 1 is housed in the columnar section 201b of the mounting table 201. The control boards 301 for the two crushing devices 1 are housed in each of the columnar sections 201b on both sides of the mounting table 201.

(Overview of the pulverizing device 1)
As shown in Figures 3 and 4, the grinding device 1 includes a grinding unit 11, a thermal insulation container 12, a hopper 13, a motor 14, and a cocoa mass removal lever 15.

The grinding unit 11 is removably housed inside a thermal insulation container (temperature-regulating container: container for regulating temperature) 12, and a hopper 13 is attached on top of the grinding unit 11. The hopper 13 houses a solid raw material. In this embodiment, the case where the solid raw material is cocoa nibs will be described. A motor 14 is provided at the bottom of the grinding device 1 and rotates the grinding section 26 of the grinding unit 11. A cocoa mass removal lever 15 is located on the side of the grinding device 1. By rotating the cocoa mass removal lever 15 downward, the cocoa mass (cocoa powder) of the cocoa nibs ground in the grinding unit 11 can be removed from the removal port 16.

Here, the cocoa mass removal lever 15 and the removal port 16 constitute the discharge section 10 that discharges the cocoa mass ground by the grinding unit 11. The discharge section 10 is detachably provided on the thermal insulation container 12. When the discharge section 10 is attached to the thermal insulation container 12, the discharge section 10 is formed so that a discharge path 10a that receives the cocoa mass from the grinding unit 11 and leads it to the removal port 16 communicates with a discharge path 35 that discharges the cocoa mass ground by the grinding unit 11.

In the crushing device 1, for cleaning purposes, the discharge section 10 and the crushing unit 11 are removably fitted to the thermal insulation container 12, and the hopper 13 is removably fitted to the crushing unit 11. In addition, the crushing unit 11 is provided with a handle (not shown), which is used to attach and detach the crushing unit 11.

As described above, the grinding unit 11 having the above configuration is detachably housed in the thermal insulation container 12. The thermal insulation container 12 maintains the conical mill and flat mill that constitute the housed grinding unit 11 at a predetermined temperature. The temperature control device equipped with the thermal insulation container 12 will be described in detail below.

(Temperature control device)
Fig. 5 is a diagram showing a schematic configuration of a temperature control device provided in the grinding device 1 shown in Fig. 3. 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, in which the diagram indicated by reference numeral 1061 is a diagram seen from above, and the diagram indicated by reference numeral 1062 is an enlarged diagram of the main part of the diagram indicated by reference numeral 1061.

The temperature control device according to this embodiment includes a thermal insulation container 12, a first fan (circulation fan) 17a for exhausting the air in the thermal insulation container 12 to the outside, a second fan (intake fan) 17b for taking in outside air into the thermal insulation container 12, a first heater (heating unit) 18a and a second heater (heating unit) 18b for heating the inside of the thermal insulation container 12, a switch 19 for turning on and off the first heater 18a and the second heater 18b, a temperature sensor (temperature detection unit) 20 for detecting the temperature inside the thermal insulation container 12, and a control unit 51 for controlling the operation of the first fan 17a, the second fan 17b, the first heater 18a, the second heater 18b, and the switch 19 according to the detection result of the temperature sensor 20. As described above, the grinding unit 11 is detachable from the grinding device 1, so the first fan 17a, the second fan 17b, the first heater 18a, and the second heater 18b are provided outside the grinding unit 11.

The thermal insulation container 12 is a generally cylindrical container that houses the grinding unit 11 inside, and forms a space around the housed grinding unit 11. The temperature in the space is maintained at a predetermined temperature by heating or cooling the air in the space. Details of this predetermined temperature will be described later. The cylindrical portion of the thermal insulation container 12 is made of glass, but is not limited to glass.

In addition, when the cylindrical portion of the thermal insulation container 12 is made of glass, there are the following advantages. That is, the grinding unit 11 can be attached and detached to the thermal insulation container, and it is possible to check through the glass whether the grinding unit is fitted in the correct position (front to back, top to bottom) inside the thermal insulation container. In addition, because it is possible to check at a glance through the glass whether the grinding unit 11 is set in the grinding device 1, it is possible to prevent the cocoa nibs from spilling into the thermal insulation container 12 if the hopper 13 is attached without inserting the grinding unit 11 and the plug (shutter) of the hopper 13 is turned by mistake.

In addition, it is possible to visually check whether or not an error has occurred, such as cocoa mass leaking from the grinding unit 11, improving visibility when cleaning the inside of the thermal insulation container 12.

The first fan 17a is, for example, a propeller fan, and is arranged on the upper surface 12a of the thermal insulation container 12 so as to face diagonally downward (towards the inside of the thermal insulation container 12) as shown in Figure 5, and functions as an exhaust fan that exhausts the air inside to the outside.

On the other hand, the second fan 17b is, for example, a sirocco fan, and is provided at a position opposite the first fan 17a on the top surface 12a of the thermal insulation container 12. It draws in outside air from the outside of the thermal insulation container 12 and expels it into the thermal insulation container 12. When the outside air is expelled from the second fan 17b, the temperature of the air in the thermal insulation container 12 is lowered. In other words, the second fan 17b functions as a cooling fan.

As described above, the thermal insulation container 12 is adapted to keep the temperature of the air inside the thermal insulation container 12 at a predetermined temperature by driving the first fan 17a and the second fan 17b to draw in air from the outside of the thermal insulation container 12 and exhaust air to the outside. To achieve the intake and exhaust of the thermal insulation container 12, the crushing device 1 is provided with a substantially disk-shaped intake and exhaust member 113 that surrounds the periphery of the inlet portion 13a of the hopper 13.

As shown in Fig. 6, the intake/exhaust member 113 has multiple slits 113a formed on concentric circles, and the multiple continuous slits 113a form the exhaust port 114 and the intake port 115. Here, the number of slits 113a used by the exhaust port 114 is greater than the number of slits 113a used by the intake port 115.

6, the intake/exhaust member 113 is made of a substantially disk-shaped member, with multiple rectangular slits 113a cut out from the center outward, arranged in a concentric pattern. Some of these slits 113a are used to form the exhaust port 114 and the intake port 115. In other words, the exhaust port 114 and the intake port 115 are formed by multiple continuous slits 113a.

The exhaust port 114 exhausts the air inside the thermal insulation container 12 to the outside. Since the intake and exhaust member 113 is provided between the hopper 13 and the thermal insulation container 12, the exhaust port 114 is provided at the top of the thermal insulation container 12.

Meanwhile, the air intake 115 takes in air into the thermal insulation container 12. A second fan 17b for intake is provided near the air intake 115, and by driving the second fan 17b, outside air can be actively introduced from the air intake 115 and exhausted into the thermal insulation container 12. As a result, the thermal insulation container 12 exhausts air from inside to the outside and takes in air from the outside. In other words, in this embodiment, the configuration actively draws in and exhausts air into the thermal insulation container 12.

Further details regarding the heating and cooling functions of the thermal insulation container 12 are as follows:

During temperature rise, the first heater 18a is installed in front of the first fan 17a, and by driving the first fan 17a, the air (hot air) heated by the first heater 18a can be sent into the thermal insulation container 12, thereby heating the entire inside of the thermal insulation container 12. The wind generated by the rotation of the first fan 17a passes through the spaces provided on the left and right of the first fan 17a (the front and back sides of the paper in FIG. 5), circulating the hot air inside the thermal insulation container 12, so that the inside of the thermal insulation container 12 can be heated efficiently.

On the other hand, when cooling, the air inside the thermal insulation container 12 that has been heated by the chimney effect is exhausted upward from the exhaust port 114. At this time, exhaust and cooling can be promoted by turning the first fan 17a ON and the first heater 18a OFF, and by using the second fan 17b (cooling fan), outside air can be taken in from the intake port 115, making it possible to efficiently cool the inside of the thermal insulation container 12.

Near the second fan 17b (below the thermal insulation container 12), a copper exhaust pipe 40 is provided to exhaust the air sucked in by the second fan 17b toward the bottom of the thermal insulation container 12. The exhaust pipe 40 is arranged to exhaust air toward the second heater 18b (heating section) on the bottom (lower part) of the thermal insulation container 12. In other words, the exhaust pipe 40 blows the air sucked in by the second fan 17b toward the conical mill and flat mill of the grinding unit 11. This prevents the conical mill and flat mill from becoming too hot, and the air warmed by the second heater 18b is pushed out by the air exhausted from the exhaust pipe 40 and moves toward the exhaust port 114 of the intake and exhaust member 113 provided on the top surface of the thermal insulation container 12. In this way, by driving the second fan 17b, air taken in through the intake port 115 of the intake and exhaust member 113 is exhausted through the exhaust pipe 40, circulates inside the thermal insulation container 112, and is exhausted through the exhaust port 114.

As described above, the number of slits 113a used by the exhaust port 114 in the intake and exhaust member 113 is greater than the number of slits 113a used by the intake port 115. This is because the intake port 115 can actively draw in air using the second fan 17b, but the exhaust port 114 does not have an exhaust fan and cannot forcibly exhaust air, so natural exhaust is achieved by using many slits 113a.

The temperature control (temperature regulation control) of the air in the thermal insulation container 12 configured as above is described below.

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

The control unit 51 controls the operation of 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 thermal insulation container 12 detected by the temperature sensor 20 at a predetermined temperature. Here, the predetermined temperature is a temperature at which the grinding of the cocoa beans, which are the material to be ground, can be optimally performed and at which the ground cocoa bean powder does not stick together.

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

The temperature inside the thermal insulation container 12 can be maintained at a predetermined temperature simply by controlling the drive of the first heater 18a and the second heater 18b. Furthermore, by adding the drive control of the first fan 17a and the second fan 17b, the temperature inside the thermal insulation container 12 can be quickly and stably maintained at a predetermined temperature.

In particular, by controlling the operation of the second fan 17b, it becomes possible to actively introduce outside air through the air intake 115 of the thermal insulation container 12, and it becomes possible to quickly cool down the air that has become too warm inside the thermal insulation container 12. This makes it possible to stably maintain the air inside the thermal insulation container 12 at a predetermined temperature.

(Discharge section 10)
Fig. 8 is a schematic cross-sectional view of the crushing device 1 shown in Fig. 3. Fig. 9 is a schematic divided cross-sectional view of the crushing device 1 shown in Fig. 3.

As shown in Figure 8, the discharge unit 10 can be attached and detached to the insulated container 12 in the direction of arrow Y (horizontal to the installation surface) perpendicular to the drive shaft X of the drive unit of the grinding unit 11 (drive shaft that turns the mortar (not shown) in the grinding unit 11). In other words, the discharge unit 10 can be attached and detached horizontally to the insulated container 12. This simplifies the configuration because there is no need to provide a member to support the discharge unit 10 in the vertical direction when it is attached to the insulated container 12.

In addition, by simply attaching the discharge unit 10 to the thermal insulation container 12, the discharge path 10a of the discharge unit 10 can be easily connected to the discharge path 35 through which the cocoa mass crushed by the grinding unit 11 is discharged.

Furthermore, a second heater 18b is provided near the discharge path 10a of the discharge section 10 and the discharge path 35 through which the cocoa mass crushed by the grinding unit 11 is discharged. By heating the connected discharge path, it is possible to prevent the cocoa mass from adhering or clogging in the discharge path.

As shown in Fig. 9, the discharge unit 10 is configured such that the cocoa mass removal lever 15 rotates around the rotation axis 15a in the direction of the arrow (the direction opposite to the discharge path 10a) relative to the main body of the discharge unit 10. On the opposite side of the lever portion 15b of the cocoa mass removal lever 15, a switching member 15c is provided for switching the discharge path 10a of the discharge unit 10 and the removal port 16 between a connected state and a non-connected state.

The switching member 15c is provided so as to be movable through the through hole 10b formed in a direction perpendicular to the outlet 16 of the discharge unit 10. When the cocoa mass removal lever 15 rotates in the direction of the arrow, the switching member 15c moves through the through hole 10b toward the thermal insulation container 12, and the discharge path 10a and the outlet 16 are connected to each other. At this time, the tip of the switching member 15c (the end on the thermal insulation container 12 side) is configured to press the grinding switch 22 provided at the bottom of the thermal insulation container 12.

Therefore, by rotating the cocoa mass removal lever 15 (by operating the cocoa mass removal lever 15 in a manner that pushes it down), the grinding switch 22 is pressed down to start grinding and to make it possible to discharge the ground material from the outlet 16. In other words, because grinding and the discharge of the ground material are linked by rotating the cocoa mass removal lever 15 in a manner that pushes it down, continuing to push down the cocoa mass removal lever 15 will continue to press the grinding switch 22, and the ground paste will be discharged one after another.

However, when the grinding device 1 is used continuously, the temperature of the grinding unit 11 rises, and as a result, the temperature of each part of the grinding device 1 rises. However, when the grinding device 1 is used again after it has sufficiently cooled down, the cocoa mass discharge path is not sufficiently warmed, so that the cocoa mass may adhere to the discharge path and become clogged. For this reason, it is preferable to control the grinding device 1 so that grinding does not start even if the cocoa mass removal lever 15 is pressed down unless the temperature in the discharge path reaches a predetermined temperature or higher. In the following embodiment 2, an example is described in which the start of grinding of the grinding device 1 is controlled according to the temperature in the discharge path.

[Embodiment 2]
Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

(Overview of the crushing device)
FIG. 10 is a schematic exploded cross-sectional view of a pulverizing device according to the second embodiment of the present invention.

As shown in FIG. 10, when the discharge unit 10 is attached to the thermal insulation container 12, a temperature sensor 21 is provided on the discharge path formed by connecting the discharge path 10a of the discharge unit 10 to the discharge path 35 on the thermal insulation container 12 side, for detecting the temperature of the discharge path, and further, a grinding switch 22 is provided which is pressed by a switching member 15c when the cocoa mass removal lever 15 of the discharge unit 10 attached to the thermal insulation container 12 is pressed down.

(Temperature control)
FIG. 11 is a block diagram of a control unit included in the crushing device shown in FIG.

The control unit 52 controls the operation of the first fan 17a, the second fan 17b, the first heater 18a, the second heater 18b, the motor 14, and the grinding switch 22 depending on the temperature of the cocoa mass discharge path in the thermal storage container 12 detected by the temperature sensor 21.

Specifically, the control unit 52 drives the first heater 18a and the second heater 18b unless the temperature detected by the temperature sensor 21 is equal to or higher than a predetermined temperature, but controls the motor 14 not to drive even if the grinding switch 22 is turned on. In other words, the control unit 52 controls the grinding device 1 not to grind unless the temperature of the discharge path for the cocoa mass in the thermal insulation container 12 is equal to or higher than a predetermined temperature. Here, the predetermined temperature is a temperature at which the grinding of the cocoa beans, which are the material to be ground, can be optimally performed and at which the powder of the ground cocoa beans (cocoa mass) does not solidify.

Therefore, if the discharge path is at or above a specified temperature, the cocoa mass will not solidify in the discharge path and will not clog.

〔summary〕
The grinding device according to aspect 1 of the present invention comprises a grinding unit 11 having a grinding section 26 that is driven to rotate and grinds a solid raw material in the grinding section 26, a temperature-controlled container (insulated container 12) that houses the grinding unit 11 inside, and a discharge section 10 that discharges the ground material produced by grinding the solid raw material by the grinding unit 11, wherein the grinding unit 11 and the discharge section 10 are detachably provided in the temperature-controlled container (insulated container 12), and when the grinding unit 11 and the discharge section 10 are attached to the temperature-controlled container (insulated container 12), a discharge path 35 for the ground material from the grinding unit 11 and a discharge path 10a for the ground material from the discharge section 10 are connected to each other.

According to the above configuration, if the crushed material becomes clogged in the discharge path of the grinding unit and the discharge path of the discharge section, the respective discharge paths can be easily checked by simply removing the grinding unit and the discharge section from the temperature-controlled container.

In the crushing device of aspect 2 of the present invention, in aspect 1, the discharge section 10 may be provided so as to be freely attached and detached in a direction perpendicular to the drive axis X of the crushing section 26.

According to the above configuration, the device can be made smaller. That is, when the discharge part is provided so as to be detachable in a direction parallel to the drive shaft of the crushing part, the lower part of the temperature-regulating container needs a space for moving the discharge part in the vertical direction (parallel to the drive shaft) to attach and detach the discharge part, and a structure for holding the discharge part and further withstanding lever operation. On the other hand, when the discharge part is provided so as to be detachable in a direction perpendicular to the drive shaft of the crushing part, the lower part of the temperature-regulating container needs a space for moving the discharge part in the front-back direction (direction perpendicular to the drive shaft), that is, a space about the size of the discharge part, but this space is smaller than the space required when the discharge part is provided so as to be detachable in a direction parallel to the drive shaft of the crushing part. Therefore, the device can be made smaller.

The grinding device according to aspect 3 of the present invention may further include a heater (second heater 18b) for heating the discharge path 35 of the grinding unit 11 and the discharge path 10a of the discharge section 10 in aspect 1 or 2.

According to the above configuration, the heater heats the discharge path of the grinding unit and the discharge path of the discharge section, thereby preventing the ground material from sticking and clogging.

The grinding device according to aspect 4 of the present invention, in any one of aspects 1 to 3, further comprises a control unit 51 for controlling the driving of the grinding section 26 of the grinding unit 11, and a temperature sensor 20 provided in the temperature control container (thermal insulation container 12) for detecting the temperature of the discharge section 10, and the control unit 51 may drive the grinding section 26 when the temperature sensor 20 detects a temperature equal to or higher than a predetermined temperature.

According to the above configuration, the crushing section will not operate unless the temperature of the discharge section reaches or exceeds a predetermined temperature. Therefore, if the predetermined temperature is set to a temperature at which the crushed material does not stick, the crushed material crushed by the crushing section will not stick in the discharge section.

The grinding device according to aspect 5 of the present invention may be configured as in aspect 3 or 4, wherein the temperature-controlled container (thermal insulation container 12) is provided with an air intake port 115, an exhaust port 114, a circulation fan (first fan 17a) for circulating the air taken in through the air intake port 115 within the temperature-controlled container (thermal insulation container 12), and a cooling fan (second fan 17b) for directing the air taken in through the air intake port 115 against an object to be cooled within the temperature-controlled container (thermal insulation container 12) and exhausting it from the exhaust port 114.

The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. The technical scope of the present invention also includes embodiments obtained by appropriately combining the technical means disclosed in the different embodiments. Furthermore, new technical features can be formed by combining the technical means disclosed in the respective embodiments.
