Detailed Description

(outline of pulverization of solid raw Material)

The pulverization of solid materials such as grains and beans is used for various foods because the use thereof is dramatically expanded by the pulverization of solid materials. However, it is also known that it is difficult to efficiently obtain a uniform pulverized product and prevent deterioration of flavor. When the grinding efficiency is regarded as important, the particles of the ground product become uneven, and the smoothness of the wheat flour, buckwheat flour, and the like is lost, so that the quality of the oolong noodles and buckwheat is deteriorated, and the flavor is easily deteriorated by oxidation due to the application of excessive heat during grinding. When excessive frictional heat is applied to the pulverized product during pulverization, fresh flavor is lost in tea, and soybean milk is a highly grassy smell. The conventional idea of pulverizing the pulverized material by slowly rotating the mortar is to suppress the generation of frictional heat, and is therefore extremely reasonable at the point of preventing the flavor of the pulverized material from deteriorating during processing.

The grinding method of adjusting the particle size of the ground material by the clearance between the rotating grindstone and the fixed grindstone like a stone mortar is basically the same even if the material is changed from natural stone to ceramic or metal. This is a typical example of dry grinding, wet grinding, and the grinding of buckwheat fruits in buckwheat production is performed in a dry manner, and the grinding of soybeans in tofu production is performed in a wet manner. The mortar-type grinding is used in various fields, and the adjustment of the clearance between the rotary grinding stone portion and the fixed grinding stone portion is performed regardless of the particle size targeted by the one-stage grinding in a dry or wet manner. In a pulverizer made of metal such as stainless steel, the clearance between the rotating blade and the fixed blade is adjusted by designing the pulverizer to pulverize a pulverized material having a desired size in a single stage.

For example, in the case of chocolate, a raw material called cocoa nibs (cacao nib) is used, which coarsely pulverizes roasted cocoa beans. In the case of crushing in shops such as chocolate booths, the gaps between mortar are adjusted in stages by the mortar method. Until the chocolate becomes a desired smooth chocolate, it is necessary to repeat the pulverization several times while gradually narrowing the clearance. The size of the material, i.e. one grain of cocoa beans, is relatively large and disadvantageous with respect to the clearance. That is, since the cocoa beans are gradually finely pulverized, it takes time to reach the target particles.

In the pulverization of cocoa beans, the melting point of cocoa beans is about 35 ℃, and the cocoa beans are made into a liquid (paste) state by the frictional heat between the cocoa nibs and a mortar at the time of pulverization of the cocoa nibs, and wet pulverization is employed. The temperature of the cocoa beans and the mortar during crushing is initially uncontrolled, depending on the process. If the temperature is low, the cocoa beans are not allowed to flow in the mortar and solidify in the grooves, and not only are they not crushed, but the load on the motor is also increased. On the other hand, in the case of an excessively high temperature, the cocoa nibs are burned, and the quality of the cocoa beans is deteriorated.

[ embodiment 1]

(outline of pulverization System)

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

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

The mounting table 201 includes a top surface portion 201a for suspending the crushing apparatus 1 and a columnar portion 201b for supporting the top surface portion 201a at both ends, and an arch (arch) is formed by the top surface portion 201a and the columnar portions 201b on both sides.

In the grinding system 101, two grinding apparatuses 1 are fixed to the table 201 such that the hopper 13 for storing the solid raw material to be ground is exposed from the upper surface of the top surface portion 201a of the table 201, and the thermal insulation 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 pulverization system 101, two pulverization apparatuses 1 are fixed in a state of being suspended on the mounting table 201.

Specifically, as shown in fig. 2, the heat-insulating container 12, which is one of the components of the pulverization apparatus 1, is fixed by a plurality of screws 401 in the top surface portion 201a of the mounting table 201.

Further, a control board 301 for driving and controlling the crushing apparatus 1 is housed in the columnar portion 201b of the mounting table 201. Further, the control boards 301 of the two pulverizing apparatuses 1 are housed in the columnar portions 201b on both sides of the mounting table 201.

(outline of the crushing apparatus 1)

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

The pulverization unit 11 is detachably housed in a heat-insulating container (temperature-adjusting container: container for adjusting temperature) 12, and a hopper 13 is attached to the pulverization unit 11. The hopper 13 contains a solid raw material. In the present 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 pulverizer 1, and rotates the pulverizing section 26 of the pulverizing unit 11. The cocoa mass extracting bar 15 is located at the side of the crushing apparatus 1. The cocoa paste take-out lever 15 is rotated downward, and thereby the cocoa paste (cocoa powder) of the cocoa nibs pulverized by the pulverization unit 11 can be taken out from the take-out port 16.

Here, the cocoa paste take-out rod 15 and the take-out port 16 constitute a discharge portion 10 that discharges the cocoa paste pulverized by the pulverizing unit 11. The discharge unit 10 is detachably provided in the heat-insulating container 12. The discharge portion 10 is formed to communicate with a discharge path 10a that receives the cocoa butter from the pulverization unit 11 and guides the cocoa butter to the extraction port 16, and a discharge path 35 that discharges the cocoa butter pulverized by the pulverization unit 11 when the discharge portion is attached to the heat insulating container 12.

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

The pulverization unit 11 configured as described above is detachably stored in the heat preservation container 12 as described above. The thermal container 12 maintains the conical mortar and the flat mortar constituting the housed pulverization unit 11 at a predetermined temperature. Hereinafter, the temperature control device including the heat insulating container 12 will be described in detail.

(temperature control device)

Fig. 5 is a view showing a schematic configuration of a temperature adjusting device included in the pulverization device 1 shown in fig. 3. Fig. 6 is a diagram showing the arrangement positions of the air inlets and the air outlets of the temperature control device shown in fig. 3, a diagram indicated by a reference numeral 1061 is a diagram seen from the top, and a diagram indicated by a reference numeral 1062 is a diagram enlarging essential parts of the diagram indicated by the reference numeral 1061.

The temperature control device of the present embodiment includes a heat-insulating container 12, a first fan (circulation fan) 17a for discharging air in the heat-insulating container 12 to the outside, a second fan (intake fan) 17b for taking in 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. Further, as described above, since the pulverization unit 11 is detachable from the pulverization apparatus 1, the first fan 17a, the second fan 17b, the first heater 18a, and the second heater 18b are provided outside the pulverization unit 11.

The heat insulating container 12 is a substantially cylindrical container that houses the pulverization unit 11 therein, and forms a space around the housed pulverization 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 regarding this predetermined temperature are described later. The cylindrical portion of the heat insulating container 12 is made of glass, but is not limited to glass.

Further, when the cylindrical portion of the heat insulating container 12 is formed of glass, there are advantages as follows. That is, in order to have a structure in which the pulverization unit 11 can be attached to and detached from the heat preservation container, whether or not the pulverization unit is fitted to a correct position (front-back, up-down) in the heat preservation container can be checked by glass. Further, since whether or not the grinding unit 11 is installed in the grinding apparatus 1 can be checked with a glass at a glance, when the funnel 13 is attached in a state where the grinding unit 11 is forgotten to be put in, and a stopper (shutter) of the funnel 13 is turned by mistake, cocoa nibs can be prevented from falling into the heat-insulating container 12.

In addition, the presence or absence of an error such as cocoa nibs leaking from the pulverization unit 11 can be visually confirmed, and the visual recognition during cleaning of the inside of the heat retention container 12 can be improved.

The first fan 17a includes, for example, a propeller fan (propeller fan), and is disposed so as to face obliquely downward (toward the inside of the heat retention container 12) on the upper surface 12a of the heat retention container 12 as shown in fig. 5, 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), is provided at a position facing the first fan 17a on the upper surface 12a of the heat insulating container 12, sucks in outside air from the outside of the heat insulating container 12, and discharges the air into the heat insulating container 12. When the outside air is discharged from this 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 discharged to the outside, thereby maintaining the temperature of the air in the heat-insulating container 12 at a predetermined temperature. In order to achieve air suction and exhaust of the heat insulating container 12, the pulverizer 1 is provided with a substantially disk-shaped air suction and exhaust member 113 surrounding the periphery of the introduction portion 13a of the hopper 13.

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

As shown in fig. 6, the air suction/discharge member 113 includes a substantially disk-shaped member, and a plurality of slits 113a cut in a rectangular shape from the center toward the outside are arranged concentrically. A part of these slits 113a serves as an exhaust port 114 and an intake port 115. That is, the exhaust port 114 and the intake port 115 are formed by the plurality of continuous slits 113 a.

The air outlet 114 discharges the air in the thermal container 12 to the outside. Since the air suction/discharge member 113 is provided between the funnel 13 and the heat insulating container 12, the air discharge port 114 is provided above the heat insulating container 12.

On the other hand, the air inlet 115 takes air into the heat insulating container 12. By providing the second fan 17b for air intake in the vicinity of the air inlet 115 and driving the second fan 17b, the outside air can be positively introduced from the air inlet 115 and discharged into the heat insulating container 12. This allows the heat-insulating container 12 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 air is positively sucked and exhausted into and from the heat insulating container 12.

The heating and cooling functions of the heat-retaining 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 entire interior of the heat-insulating container 12 can be heated. Since the air generated by the rotation of the first fan 17a circulates the hot air in the heat-insulating container 12 through the spaces (the front side and the back side of the paper in fig. 5) provided on the left and right sides of the first fan 17a, the inside of the heat-insulating container 12 can be heated efficiently.

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

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 in the vicinity of 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 heat insulating container 12. That is, the discharge duct 40 blows out the air sucked by the second fan 17b toward the tapered mortar and the flat mortar of the pulverization unit 11. This prevents the taper mortar and the flat mortar from being excessively heated, 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 suction/exhaust member 113 provided on the top surface of the thermal insulation container 12. When the second fan 17b is driven in this manner, the air taken in through the air inlet 115 of the air intake/exhaust member 113 is discharged through the discharge pipe 40, circulated through the inside of the heat-insulating container 12, and discharged through the air outlet 114.

As described above, the number of the slits 113a used for the exhaust port 114 of the air intake/exhaust member 113 is larger than the number of the slits 113a used for the air intake port 115. This is because the air can be positively sucked by the second fan 17b through the air inlet 115, but the air cannot be forcibly discharged because no air-discharging fan is provided in the air outlet 114, and therefore, the air is naturally discharged through the large number of slits 113 a.

The temperature control (temperature adjustment control) of the air in the heat-insulating container 12 configured as described above will be described below.

(temperature control)

Fig. 7 is a block diagram of a control unit that controls the temperature control device included in the pulverizer 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 retention container 12 detected by the temperature sensor 20 at a predetermined temperature. Here, the predetermined temperature is a temperature at which the pulverization of the pulverized cocoa beans is optimally performed and the pulverized cocoa beans are not fixed to each other.

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

The temperature in the heat-retaining container 12 can be maintained at a predetermined temperature by controlling the driving of only the first heater 18a and the second heater 18 b. In addition, by controlling the driving of the first fan 17a and the second fan 17b, the temperature in the heat retention 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 actively introduced from the air inlet 115 of the heat-insulating container 12, and the air that has been excessively heated can be quickly cooled in the heat-insulating container 12. This allows the air in the thermal container 12 to be stably maintained at a predetermined temperature.

(discharge part 10)

Fig. 8 is a schematic sectional view of the pulverizer 1 shown in fig. 3. Fig. 9 is a schematic sectional view of the pulverizer 1 shown in fig. 3.

As shown in fig. 8, the discharge unit 10 is detachably attached to the heat insulating container 12 in a direction indicated by an arrow Y (a direction horizontal to the installation surface) perpendicular to a drive shaft X of a drive unit of the pulverization unit 11 (a drive shaft for rotating a mortar (not shown) in the pulverization unit 11). That is, the discharge unit 10 is detachable from the heat insulating container 12 in the horizontal direction. Thus, when the discharge unit 10 is attached to the thermal insulation container 12, it is not necessary to provide a member for supporting the discharge unit 10 in the vertical direction, and the configuration can be simplified.

Further, only 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 through which the cocoa paste pulverized by the pulverization unit 11 is discharged 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 for discharging the cocoa paste pulverized by the pulverizing means 11, and the connected discharge path is heated, the fixation and clogging of the cocoa paste in the discharge path can be prevented.

In the discharging section 10, as shown in fig. 9, the cocoa paste extracting rod 15 rotates in the arrow direction (the direction opposite to the discharging path 10 a) with respect to the main body of the discharging section 10 around the rotation shaft 15 a. A switching member 15c for switching the discharge path 10a of the discharge portion 10 and the discharge port 16 between a communicating state and a non-communicating state is provided on the side opposite to the stem portion 15b of the cacao butter extraction lever 15.

The switching member 15c is provided with a through hole 10b formed in a direction orthogonal to the extraction port 16 of the discharge portion 10 so as to be movable, and when the cocoa paste extraction rod 15 is rotated in the arrow direction, the switching member 15c moves the through hole 10b toward the thermal container 12 side to establish a communication state in which the discharge path 10a and the extraction port 16 communicate with each other. At this time, the tip (end on the side of the thermal insulation container 12) of the switching member 15c presses down the mill switch 22 provided in the lower portion of the thermal insulation container 12.

Therefore, by rotating the cacao butter removal lever 15 (operating to press down the cacao butter removal lever 15), the pulverization switch 22 can be pressed down to start pulverization, and the pulverized material can be discharged from the discharge port 16. That is, the pulverization and the delivery of the pulverized material are interlocked by rotating the cacao butter removal lever 15 so as to be pressed down, and the pulverization switch 22 is continuously pressed down by continuously pressing down the cacao butter removal lever 15, so that the pulverized butter is continuously delivered.

Incidentally, if the pulverizer 1 is continuously used, the temperature of the pulverizing unit 11 rises, and as a result, the temperature of each part of the entire pulverizer 1 rises. However, when the milling apparatus 1 is used again after being sufficiently cooled, the cocoa mass may be fixed and clogged in the discharge path because the discharge path of the cocoa mass is not sufficiently heated. Therefore, if the temperature in the discharge path is not equal to or higher than the predetermined temperature, it is preferable to control the pulverization device 1 so as not to start the pulverization even if the cacao butter removal lever 15 is pressed down. In embodiment 2 below, an example of control for starting pulverization in the pulverizer 1 based on the temperature in the discharge path will be described.

[ embodiment 2]

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

(outline of the grinding apparatus)

As shown in fig. 10, when the discharge unit 10 is attached to the heat-retaining container 12, a temperature sensor 21 for detecting the temperature of the discharge path is provided in the discharge path formed by communicating the discharge path 10a of the discharge unit 10 with the discharge path 35 on the heat-retaining container 12 side, and a grind switch 22 is provided which is pressed by the switching member 15c when the cacao butter extraction lever 15 attached to the discharge unit 10 of the heat-retaining container 12 is pressed.

(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 cocoa butter discharge path in the thermal insulation 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 the predetermined temperature, the control unit 52 drives the first heater 18a and the second heater 18b, and controls the motor 14 not to be driven even if the pulverization switch 22 is turned ON. That is, if the temperature of the cocoa paste discharge path in the thermal container 12 is not equal to or higher than the predetermined temperature, the control unit 52 controls the pulverization of the pulverization device 1 so as not to be performed. Here, the predetermined temperature is a temperature at which the pulverization of the pulverized cocoa beans is optimally performed and the pulverized cocoa bean powder (cocoa paste) is not fixed.

Therefore, if the discharge path is at a predetermined temperature or higher, the cocoa mass does not adhere to the discharge path and is not clogged.

According to the above configuration, when the discharge path of the pulverization unit and the discharge path of the discharge unit are clogged with the pulverized material, the pulverization unit and the discharge unit can be simply taken out from the temperature control container, and the respective discharge paths can be easily checked.

In the crushing apparatus according to claim 2 of the present invention according to claim 1, the discharge unit 10 may be detachably provided in a direction orthogonal to the drive axis X of the crushing unit 26.

According to 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 pulverization portion, the discharge portion is moved in the vertical direction (direction parallel to the drive shaft) in the lower portion of the temperature control container, and a space for attaching and detaching the discharge portion and a structure for holding the discharge portion are required, and the lever operation is further endured. In contrast, in the case where the discharge portion is detachably provided in the direction orthogonal to the drive shaft of the pulverization portion, a space for moving the discharge portion in the front-rear direction (the direction orthogonal to the drive shaft), that is, a space of about the size of the discharge portion is necessary in the lower portion of the temperature control container, but this space may be smaller than a space in the case where the discharge portion is detachably provided in the direction parallel to the drive shaft of the pulverization portion. Therefore, the device can be miniaturized.

The crushing apparatus according to claim 3 of the present invention may be such that, in claim 1 or 2, the crushing apparatus further includes: and a heater (second heater 18b) for heating the discharge path 35 of the pulverization unit 11 and the discharge path 10a of the discharge portion 10.

According to the above configuration, since the discharge path of the pulverization unit and the discharge path of the discharge portion are heated by the heater, the pulverized material can be prevented from being fixed to each other and clogging can be prevented.

The crushing apparatus according to aspect 4 of the present invention may be the crushing apparatus according to any one of aspects 1 to 3, further comprising: a control unit 51 for driving and controlling the pulverization unit 26 of the pulverization unit 11; and a temperature sensor 20 provided in the thermal container (thermal container 12) for detecting the temperature of the discharge portion 10; wherein the control part 51 drives the crushing part 26 when the temperature sensor 20 detects a temperature higher than a predetermined temperature.

According to the above configuration, when the temperature of the discharge portion is not equal to or higher than the predetermined temperature, the pulverization portion is not driven, and when the predetermined temperature is set to a temperature at which the pulverized material is not fixed, the pulverized material pulverized by the pulverization portion is not fixed to the discharge portion.
