Detailed Description

(outline of pulverization of solid raw materials)

The pulverization of solids such as cereals and beans has been widely used because of the dramatic expansion of the use of the pulverized solids. However, it is also known that it is difficult to efficiently obtain a uniform pulverized product and to prevent deterioration of flavor. Not only is the grinding efficiency emphasized, but also the particles of the ground product become uneven in size, lose smoothness to wheat flour, buckwheat flour, etc., and the quality of oolong flour and buckwheat is degraded, and deterioration of flavor due to oxidation is easily caused by excessive heat applied during grinding. When excessive frictional heat is added to the pulverized product during pulverization, fresh flavor is lost to tea, and soybean milk is a strong grass smell product. The conventional idea of pulverizing a pulverized product by slowly rotating a mortar is quite reasonable in so-called prevention of deterioration of flavor of the pulverized product during processing because frictional heat generation is suppressed.

The basic idea is the same, in which the grinding mode of adjusting the particle size of the crushed material is to change the material from natural stone to ceramic or metal, by the clearance between the stone rotated like a stone mortar and the fixed stone. In the dry grinding, grinding of the buckwheat fruits in the production of buckwheat is performed in a dry manner, and grinding of soybean in the production of bean curd is performed in a wet manner, similarly to the wet grinding. Grinding by stone grinding is used in various fields, and is performed by adjusting the clearance between a rotating grinding stone portion and a fixed grinding stone portion, regardless of the particle size of the target particles for grinding in one stage, such as dry grinding and wet grinding. In a pulverizer made of a metal such as stainless steel, the clearance between the rotating blade and the fixed blade is adjusted so that the pulverized material is one-stage pulverized into a desired size.

For example, in the case of chocolate, a raw material called cocoa nibs (cacao nib) is used that coarsely pulverizes roasted cocoa beans. In the case of crushing a store such as a chocolate house, the clearance between stone holes is adjusted stepwise by the stone hole method. In order to obtain a desired smooth chocolate, it is necessary to grind the chocolate repeatedly a plurality of times while gradually narrowing the clearance. The size of one grain of the raw material, i.e., cocoa beans, is relatively large with respect to the clearance. That is, since the cocoa beans are gradually finely pulverized, it takes time until reaching the targeted particles.

In the pulverization of cocoa beans, the melting point of the cocoa beans is about 35 ℃, and the cocoa beans are brought into a liquid (paste) state by friction heat between the mortar and the cocoa particles during the pulverization of the cocoa particles, and wet pulverization is employed. The temperature of the cocoa beans and the mortar during comminution is not previously controlled depending on the process. If the temperature is low, the cocoa beans cannot flow in the mortar and solidify in the grooves, so that not only cannot be crushed, but also the load on the motor increases. On the other hand, in case of too high temperature, the cocoa nibs are burnt, and the quality of the cocoa beans is reduced.

Embodiment 1

(overview of pulverizing System)

Fig. 1 is a perspective view of a pulverizing system according to the present embodiment. Fig. 2 is a schematic cross-sectional view of the main part of the pulverizing system shown in fig. 1.

As shown in fig. 1, the pulverizing system 101 includes two pulverizing devices 1 and a stage 201 on which the pulverizing devices 1 are mounted.

The mounting table 201 includes a top surface portion 201a on which the pulverizing device 1 is suspended, and columnar portions 201b that support the top surface portion 201a at both ends, and arches (arches) are formed by the top surface portion 201a and the columnar portions 201b at both sides.

The pulverizing system 101 is configured to fix two pulverizing devices 1 to the mounting table 201 such that the hopper 13 for storing solid raw materials, which are objects to be pulverized, is exposed from the upper surface of the top surface portion 201a of the mounting table 201, and the heat-insulating container 12, the motor 14, and the discharge portion 10 are exposed from the lower surface of the top surface portion 201 a. That is, in the pulverizing system 101, the two pulverizing devices 1 are fixed in a state suspended from the mounting table 201.

Specifically, as shown in fig. 2, in the top surface portion 201a of the mounting table 201, the thermal insulation container 12, which is one of the constituent elements of the pulverizing device 1, is fixed by a plurality of screws 401.

In addition, a control board 301 for driving and controlling the pulverizing apparatus 1 is housed in the columnar portion 201b of the mounting table 201. The control boards 301 of the two pulverizing devices 1 are respectively accommodated in the columnar portions 201b on both sides of the mounting table 201.

(outline of crushing apparatus 1)

As shown in fig. 3 and 4, the pulverizing apparatus 1 includes a pulverizing unit 11, a thermal container 12, a hopper 13, a motor 14, and a cocoa paste take-out lever 15.

The pulverizing unit 11 is detachably housed in a heat-insulating container (temperature-adjusting container: container for temperature adjustment) 12, and a hopper 13 is attached to the pulverizing unit 11. The hopper 13 accommodates a solid raw material. In this embodiment, a case where the solid raw material is cocoa nibs will be described. The motor 14 is provided at a lower portion of the pulverizing device 1, and rotates the pulverizing portion 26 of the pulverizing unit 11. The cocoa butter withdrawal lever 15 is located at the side of the comminuting device 1. The cocoa paste extraction lever 15 is rotated downward, whereby the cocoa paste (cocoa powder) of the cocoa particles crushed by the crushing unit 11 can be extracted from the extraction port 16.

Here, the cocoa paste extraction rod 15 and the extraction port 16 constitute an extraction unit 10 for extracting the cocoa paste pulverized by the pulverizing unit 11. The discharge portion 10 is detachably provided in the thermal insulation container 12. The discharge portion 10 is formed so as to communicate a discharge path 10a for receiving the cocoa paste from the pulverizing unit 11 and guiding the cocoa paste to the discharge port 16 and a discharge path 35 for discharging the cocoa paste pulverized by the pulverizing unit 11 when the cocoa paste is mounted in the thermal container 12.

In the pulverizing apparatus 1, the discharge portion 10 and the pulverizing unit 11 are detachably fitted to the heat-insulating container 12, and the hopper 13 is detachably fitted to the pulverizing unit 11 for cleaning. Further, a handle (not shown) is provided in the pulverizing unit 11, and the pulverizing unit 11 is attached and detached by the handle.

The pulverizing unit 11 having the above-described configuration is detachably accommodated in the heat-insulating container 12 as described above. The heat-insulating container 12 maintains the tapered mortar and the flat mortar constituting the housed pulverizing unit 11 at a predetermined temperature. In the following, details of the temperature regulating device including the thermal insulation container 12 are described.

(temperature regulating device)

Fig. 5 is a diagram showing a schematic configuration of a temperature control device included in the pulverizing apparatus 1 shown in fig. 3. Fig. 6 is a diagram showing the arrangement positions of the air inlet and the air outlet of the temperature control device shown in fig. 3, wherein the diagram indicated by a symbol 1061 is a diagram seen from above, and the diagram indicated by a symbol 1062 is an enlarged diagram of an essential part of the diagram indicated by a symbol 1061.

The temperature control device of the present embodiment includes a heat-insulating container 12, a first fan (circulation fan) 17a for exhausting air in the heat-insulating container 12 to the outside, a second fan (intake fan) 17b for taking outside air into the heat-insulating container 12, a first heater (heating unit) 18a and a second heater (heating unit) 18b for heating the inside of the heat-insulating 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 in the heat-insulating container 12, and a control unit 51 for controlling the driving of the first fan 17a, the second fan 17b, the first heater 18a, the second heater 18b, and the switch 19 based ON the detection result of the temperature sensor 20. As described above, the pulverizing unit 11 is detachable from the pulverizing apparatus 1, and the first fan 17a, the second fan 17b, the first heater 18a, and the second heater 18b are provided outside the pulverizing unit 11.

The heat-insulating container 12 is a substantially cylindrical container in which the pulverizing unit 11 is housed, and a space is formed around the housed pulverizing unit 11. The air present in the space is heated and cooled, and the temperature in the space is maintained at a predetermined temperature. Details of this predetermined temperature will be described later. The cylindrical portion of the insulating container 12 is formed of glass, but is not limited to glass.

In addition, when the cylindrical portion of the heat insulating container 12 is formed of glass, there are advantages as follows. That is, in order to make it possible to attach and detach the pulverizing unit 11 to and from the thermal insulation container, it is possible to confirm whether or not the pulverizing unit is fitted to a correct position (front, rear, up and down) in the thermal insulation container by glass. Further, since it is possible to confirm at a glance whether or not the pulverizing unit 11 is provided in the pulverizing apparatus 1, if the funnel 13 is attached in a state where the pulverizing unit 11 is forgotten to be put in, the cocoa particles can be prevented from falling into the heat-insulating container 12 by erroneously rotating the lock (shutter) of the funnel 13.

In addition, whether or not there is an error in leaking cocoa particles or the like from the pulverizing unit 11 can be visually checked, and the visual recognition at the time of cleaning the inside of the thermal insulation container 12 can be improved.

The first fan 17a includes, for example, a propeller fan (propeller fan), and as shown in fig. 5, is disposed on the upper surface 12a of the heat insulating container 12 so as to face obliquely downward (inside the heat insulating container 12), and functions as an exhaust fan that exhausts the air inside to the outside.

On the other hand, the second fan 17b includes, for example, a sirocco fan (sirocco fan), and is provided on the upper surface 12a of the heat-insulating container 12 at a position facing the first fan 17a, and sucks outside air from outside the heat-insulating container 12 and discharges the outside air into the heat-insulating container 12. 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 is driven by the first fan 17a and the second fan 17b, and the air is sucked from the outside of the heat-insulating container 12 and exhausted to the outside, thereby maintaining the temperature of the air in the heat-insulating container 12 at a predetermined temperature. In order to realize the air intake and exhaust of the thermal container 12, the pulverizing device 1 is provided with a substantially disk-shaped air intake and exhaust member 113 surrounding the periphery of the introduction portion 13a of the hopper 13.

As shown in fig. 6, the air intake and exhaust member 113 has a plurality of slits 113a formed on a concentric circle, and an air outlet 114 and an air inlet 115 are formed by the plurality of slits 113a in series. Here, the number of slits 113a used for the exhaust port 114 is larger than the number of slits 113a used for the intake port 115.

As shown in fig. 6, the air intake/exhaust member 113 includes a substantially disk-shaped member, and a plurality of slits 113a cut from the center to the outside into a rectangular shape are arranged in concentric circles. A part of these slits 113a is used as the exhaust port 114 and the intake port 115. That is, the exhaust port 114 and the intake port 115 are formed by a plurality of slits 113a in series.

The exhaust port 114 exhausts the air in the thermal insulation container 12 to the outside. Since the air intake and exhaust member 113 is provided between the funnel 13 and the thermal insulation container 12, the air exhaust port 114 is provided at the upper portion of the thermal insulation container 12.

On the other hand, the air inlet 115 takes in air into the heat-insulating container 12. A second fan 17b for sucking air is provided near the air inlet 115, and the second fan 17b is driven to actively introduce external air from the air inlet 115 and discharge the air into the thermal insulation container 12. Thus, the heat-insulating container 12 is configured to discharge the air inside to the outside and to take in the air from the outside. In other words, in the present embodiment, the structure of sucking and exhausting air into and from the heat-insulating container 12 is positively performed.

The temperature raising and cooling functions of the heat-insulating container 12 are complemented as follows.

When the temperature is raised, the first heater 18a is provided in front of the first fan 17a, and the first fan drive 17a is driven, whereby the air (hot air) heated by the first heater 18a can be sent into the heat-insulating container 12, and the whole inside of the heat-insulating container 12 can be heated. The air generated by the rotation of the first fan 17a circulates the hot air in the heat-insulating container 12 through spaces provided on the left and right sides (the front side and the back side of the drawing sheet in fig. 5) of the first fan 17a, and thus the heat-insulating container 12 can be efficiently heated.

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

A copper discharge pipe 40 for discharging the air sucked by the second fan 17b toward the bottom of the heat-insulating container 12 is provided near the second fan 17b (below the heat-insulating container 12). The discharge pipe 40 is disposed so as to discharge air toward the second heater 18b (heating portion) on the bottom surface (lower portion) of the thermal insulation container 12. That is, the discharge duct 40 blows out the air sucked by the second fan 17b toward the conical mortar and the flat mortar of the pulverizing unit 11. This prevents the taper and flat mortar from becoming excessively high temperature, and the air heated by the second heater 18b is pushed out by the air discharged from the discharge pipe 40 and moves toward the exhaust port 114 of the air intake/exhaust member 113 provided on the top surface of the thermal insulation container 12. By driving the second fan 17b in this way, the air taken in through the air intake port 115 of the air intake/exhaust member 113 is discharged through the exhaust pipe 40, circulated inside the thermal insulation container 12, and discharged through the air exhaust port 114.

As described above, the number of slits 113a used in the exhaust port 114 of the air intake and exhaust member 113 is larger than the number of slits 113a used in the air intake port 115. This is because, although the second fan 17b can actively suck air in the air inlet 115, the air outlet 114 is not provided with a fan for exhausting air, and thus cannot be exhausted forcibly, and thus is naturally exhausted by a large number of slits 113 a.

The temperature control (temperature control) of the air in the thermal insulation container 12 having the above-described structure will be described below.

(temperature control)

Fig. 7 is a block diagram of a control unit for controlling the temperature control device included in the pulverizing device 1 shown in fig. 3.

The control unit 51 controls the driving 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 in the heat-insulating container 12 detected by the temperature sensor 20 at a predetermined temperature. Here, the predetermined temperature is set to a temperature at which the pulverized product, that is, the cocoa beans, are pulverized optimally, and the pulverized cocoa beans are not fixed to the powder.

Specifically, the control unit 52 controls the driving of the first heater 18a and the second heater 18b and controls the driving of the first fan 17a and the second fan 17b so that the temperature in the heat-insulating container 12 detected by the temperature sensor 20 is maintained at a predetermined temperature.

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

In particular, by controlling the driving of the second fan 17b, the outside air can be positively introduced from the air inlet 115 of the heat-insulating container 12, and the overheated air can be rapidly cooled in the heat-insulating container 12. This can stably maintain the air in the heat-insulating container 12 at a predetermined temperature.

(discharge portion 10)

Fig. 8 is a schematic cross-sectional view of the pulverizing apparatus 1 shown in fig. 3. Fig. 9 is a schematic sectional divided view of the pulverizing apparatus 1 shown in fig. 3.

As shown in fig. 8, the discharge unit 10 is detachable from the thermal insulation container 12 in an arrow Y direction (a direction horizontal to the installation surface) orthogonal to a drive shaft (a drive shaft for rotating a mortar (not shown) in the pulverizing unit 11) X of the drive unit of the pulverizing unit 11. That is, the discharge portion 10 is detachable from the thermal insulation container 12 in the horizontal direction. Accordingly, when the discharge portion 10 is attached to the thermal insulation container 12, it is unnecessary to provide a member for supporting the discharge portion 10 in the vertical direction, and the structure can be simplified.

Further, by attaching only the discharge portion 10 to the thermal insulation container 12, the discharge path 10a of the discharge portion 10 and the discharge path 35 of the cocoa paste crushed by the discharge crushing means 11 can be easily communicated.

Further, since the second heater 18b is provided in the vicinity of the discharge path 10a of the discharge portion 10 and the discharge path 35 of the cocoa paste crushed by the discharge crushing unit 11, the discharge path in thermal communication is heated, and thus the fixation and clogging of the cocoa paste in the discharge path can be prevented.

In the discharge portion 10, as shown in fig. 9, the cocoa paste extraction lever 15 rotates in the arrow direction (the direction opposite to the discharge path 10 a) about the rotation axis 15a with respect to the main body of the discharge portion 10. On the opposite side of the stem portion 15b of the cocoa paste extraction stem 15, a switching member 15c for switching the discharge path 10a of the discharge portion 10 to the extraction port 16 between a communication state and a non-communication state is provided.

The switching member 15c is provided with a through hole 10b formed in a direction orthogonal to the outlet 16 of the discharge unit 10 so as to be movable, and when the cocoa paste extraction lever 15 is rotated in the arrow direction, the switching member 15c moves the through hole 10b toward the heat-insulating container 12 side, thereby communicating the discharge path 10a with the outlet 16. At this time, the tip (end on the side of the heat-insulating container 12) of the switching member 15c presses down the pulverization switch 22 provided at the lower portion of the heat-insulating container 12.

Therefore, by rotating the cocoa paste extraction lever 15 (operating so as to press down the cocoa paste extraction lever 15), the grinding switch 22 can be depressed, grinding can be started, and the ground product can be discharged from the extraction port 16. That is, since the cocoa paste extraction lever 15 is rotated so as to be pressed down, the pulverization and the delivery of the pulverized material are linked, and since the cocoa paste extraction lever 15 is continuously pressed down, the pulverization switch 22 is continuously pressed down, and the pulverized paste is continuously delivered.

Incidentally, if the pulverizing apparatus 1 is continuously used, the temperature of the pulverizing unit 11 increases, and as a result, the temperature of each part of the entire pulverizing apparatus 1 increases. However, when the pulverizing device 1 is used again after the pulverizing device 1 is sufficiently cooled, the cocoa paste is not sufficiently heated in the discharge path, and there is a concern that the cocoa paste is fixed and clogged in the discharge path. Therefore, if the temperature in the discharge path is not equal to or higher than the predetermined temperature, it is preferable to control so as not to start pulverization by the pulverizing device 1 even if the cocoa paste extraction lever 15 is pressed down. In embodiment 2 below, an example of control of starting pulverization by the pulverizing device 1 according to the temperature in the discharge path will be described.

Embodiment 2

Other embodiments of the present application will be described below. For convenience of explanation, members having the same functions as those of the members described in the above embodiments are given the same reference numerals, and the explanation thereof will not be repeated.

(outline of pulverizing apparatus)

As shown in fig. 10, when the discharge unit 10 is attached to the thermal container 12, a temperature sensor 21 for detecting the temperature of the discharge path is provided in the discharge path formed by connecting the discharge path 10a of the discharge unit 10 and the discharge path 35 on the thermal container 12 side, and a crushing switch 22 which is pushed down by a switching member 15c when the cocoa paste extraction lever 15 attached to the discharge unit 10 of the thermal container 12 is pushed down is provided.

(temperature control)

The control unit 52 controls the driving of the first fan 17a, the second fan 17b, the first heater 18a, the second heater 18b, the motor 14, and the pulverization switch 22 based on the temperature of the discharge path of the cocoa paste in the thermal container 12 detected by the temperature sensor 21.

Specifically, if the temperature detected by the temperature sensor 21 is not equal to or higher than a predetermined temperature, the control unit 52 drives the first heater 18a and the second heater 18b, and controls not to drive the motor 14 even if the grinding switch 22 is turned ON. That is, if the temperature of the discharge path of the cocoa paste in the thermal container 12 is not equal to or higher than the predetermined temperature, the control unit 52 controls not to crush the crushing device 1. Here, the predetermined temperature is set to a temperature at which the pulverized product, that is, the cocoa beans, are pulverized optimally, and the pulverized cocoa powder (cocoa paste) is not fixed.

Therefore, if the discharge path is at a predetermined temperature or higher, the cocoa paste is not fixed in the discharge path, and thus is not clogged.

[ summary ]

The pulverizing apparatus according to embodiment 1 of the present application includes: a pulverizing unit 11 including a pulverizing unit 26 rotationally driven, and pulverizing the solid raw material by the pulverizing unit 26; a temperature-adjusting container (thermal container 12) for accommodating the pulverizing unit 11 therein; and a discharge unit 10 for discharging the pulverized product obtained by pulverizing the solid raw material by the pulverizing unit 11; wherein the pulverizing unit 11 and the discharge portion 10 are detachably provided with respect to the temperature adjustment container (heat preservation container 12); when the pulverizing unit 11 and the discharge portion 10 are mounted in the temperature-adjusting container (heat-insulating container 12), the discharge path 35 of the pulverized material of the pulverizing unit 11 communicates with the discharge path 10a of the pulverized material of the discharge portion 10.

According to the above configuration, when the discharge path of the pulverizing unit and the discharge path of the discharge portion are clogged, the pulverizing unit and the discharge portion are taken out of the temperature adjustment container alone, and the respective discharge paths can be easily checked.

In the pulverizing device according to claim 2 of the present application, in the above-described claim 1, the discharge portion 10 may be detachably provided in a direction orthogonal to the drive shaft X of the pulverizing portion 26.

With the above configuration, the device can be miniaturized. That is, in the case where the discharge portion is detachably provided in a direction parallel to the drive shaft of the crushing portion, a space for attaching and detaching the discharge portion and a structure for holding the discharge portion are required to further withstand the lever operation by moving the discharge portion in the up-down direction (direction parallel to the drive shaft) in the lower portion of the temperature adjustment container. In contrast, in the case where the discharge portion is detachably provided in a direction orthogonal to the drive shaft of the pulverizing portion, a space for moving the discharge portion in the front-rear direction (direction orthogonal to the drive shaft), that is, a space for the discharge portion in the left-right direction is required in the lower portion of the temperature adjustment container, but this space may be smaller than in the case where the discharge portion is detachably provided in a direction parallel to the drive shaft of the pulverizing portion. Therefore, the device can be miniaturized.

The pulverizing apparatus according to claim 3 of the present application may further include, in either claim 1 or claim 2: a heater (second heater 18 b) heats the discharge path 35 of the pulverizing unit 11 and the discharge path 10a of the discharge portion 10.

According to the above configuration, the heater heats the discharge path of the pulverizing unit and the discharge path of the discharge portion, so that the fixation of the pulverized material can be prevented and clogging can be prevented.

The pulverizing device according to claim 4 of the present application may further include, in any one of claims 1 to 3: a control unit 51 for driving and controlling the pulverizing unit 26 of the pulverizing unit 11; and a temperature sensor 20 provided in the thermal container (thermal container 12) and detecting the temperature of the discharge portion 10; wherein the control unit 51 drives the pulverizing unit 26 when the temperature sensor 20 detects a temperature equal to or higher than a predetermined temperature.

According to the above configuration, since the pulverizing unit is not driven if the temperature of the discharge unit is not equal to or higher than the predetermined temperature, the pulverized material pulverized by the pulverizing unit is not fixed to the discharge unit if the predetermined temperature is set to a temperature at which the pulverized material is not fixed.

In the pulverizing apparatus according to claim 5 of the present application, in claim 3 or 4, the heat-insulating container (heat-insulating container 12) may include: an air inlet 115; an exhaust port 114; a circulation fan (first fan 17 a) for circulating the air sucked through the air inlet 115 into the heat-insulating container (heat-insulating container 12); and a cooling fan (second fan 17 b) for exhausting air sucked through the air inlet 115 from the air outlet 114 by touching the object to be cooled in the heat-insulating container (heat-insulating container 12).
