Description

  The present invention relates to a cocoon treatment apparatus for pulverizing and discharging cocoons generated in a general household kitchen or a commercial kitchen, and more particularly to a cocoon treatment apparatus for improving the discharge performance of cocoons having a long fiber. is there.

As a conventional technique, there is a soot processing device that performs continuous operation for continuously driving a motor unit (see, for example, Patent Document 1).
In the soot processing apparatus that performs such continuous operation, since the motor unit is continuously driven, soot having a long fiber can be discharged to the discharge unit in a short time.
However, the cocoon having a long fiber is discharged to the discharge part while having a long fiber without being sufficiently pulverized. Therefore, there is a problem that a large amount of pulverized material discharged to the discharge portion without being sufficiently pulverized in a short time is entangled in a lump at the inlet of the discharge port or at the trap portion connected to the discharge port, resulting in clogging.

Further, as a conventional technique, there is a scissor processing device in which an impeller extending downward is provided on the lower surface of a rotating plate (see, for example, Patent Document 2).
In the soot treatment apparatus provided with such an impeller, the impeller pushes out the drainage or pulverized material of the drainage section by the rotation of the rotating plate, so that the flow rate of drainage to the discharge port increases. For this reason, the discharge performance which discharges soot from a discharge port improves remarkably.
However, the soot having a long fiber is not sufficiently pulverized and is discharged to the discharge portion while having a long fiber, so that if the flow rate of the drainage to the discharge port is increased by the impeller, it is sufficiently pulverized. A large amount of crushed material will be discharged from the discharge port in a shorter time than the above-described soot processing apparatus that performs continuous operation, and entangled in a lump at the inlet of the discharge port or at the trap connected to the discharge port, There was a problem that clogging was more likely to occur.

Further, as a conventional technique, there is a soot processing device that performs intermittent operation in which a motor unit is intermittently driven. (For example, refer to Patent Document 3).
In the soot processing apparatus that performs such intermittent operation, the motor unit is intermittently driven, so that the discharge amount per unit time becomes small. Therefore, although the pulverized product discharged to the discharge part is not sufficiently pulverized, the ratio of the weight of the pulverized product to be contained with respect to the amount of water in the drainage is less than the continuous operation in the OFF time provided. Since a certain pulverized product concentration becomes small, it is not entangled in a lump at the discharge port or at the trap portion connected to the discharge port.
However, although the problem of clogging at the discharge port and the trap portion can be solved, the time required for pulverizing all the slag in the pulverization chamber increases because the slag is pulverized by intermittent operation.
Therefore, in the soot processing apparatus that performs such intermittent operation, when the soot having a long fiber is pulverized, the pulverization processing time is set long, or the amount of soot that is put into the pulverization chamber at a time is reduced. It has to be either one of the above or the other, and it is very inconvenient.

JP 2003-80102 A (page 3, FIG. 1) Japanese Patent No. 3420305 (page 5, FIG. 3) Japanese Patent Laid-Open No. 2002-204972 (page 6, FIG. 3)

  The present invention has been made to solve the above problems, and an object of the present invention is to discharge a cocoon having a long fiber without causing clogging at the inlet of the outlet or the trap portion connected to the outlet. It is possible to provide a soot processing device that can perform pulverization and discharge processing in a relatively short time.

In order to achieve the above object, according to the first aspect of the present invention, there is provided a pulverizing section comprising: a pulverizing chamber communicating with the charging port for introducing the soot; a rotating plate provided at the bottom of the pulverizing chamber; , A drive unit for rotating the rotating plate, a discharge unit having a discharge port for discharging the soot crushed by the crushing unit, a water supply unit for supplying cleaning water to the crushing chamber, and controlling the operation of the drive unit and the water supply unit And a control unit that performs the intermittent operation O1 that intermittently drives the drive unit for a predetermined time while providing an impeller extending downward on the lower surface of the rotating plate.
In the present invention configured as described above, since the drive unit is driven intermittently, the discharge amount per unit time is reduced. Therefore, the pulverized product discharged to the discharge part is not pulverized sufficiently, but the pulverized product discharge concentration, which is the ratio of the weight of the pulverized product in the amount of waste water, becomes small, so at the discharge port or at the trap connected to the discharge port There is no entanglement in the lump.
Since the impeller extending downward is provided on the lower surface of the rotating plate, the impeller pushes out the drainage or pulverized material of the drainage portion by the rotation of the rotating plate, so that the flow rate of the drainage to the discharge port increases. Therefore, even when the drive of the intermittent operation O1 is OFF, the flow rate of the drainage to the discharge port can be maintained at a predetermined flow rate or more, and the pulverized material of the drainage unit can be discharged to the discharge port. That is, an appropriate amount of pulverized material can be discharged from the discharge port not only when the drive of the intermittent operation O1 is turned on but also when it is turned off, so that the pulverization and discharge process can be performed in a relatively short time. .
Moreover, when switching the drive of the intermittent operation O1 from OFF to ON, since the impeller is provided, the flow rate of drainage to the discharge port can be instantaneously increased. Therefore, even when there is a pulverized product that has been stuck due to being caught at the inlet of the discharge port when the drive of the drive unit is turned on, the catch of the drive unit is canceled when the drive of the drive unit is turned off. By instantly increasing the flow rate of the drainage to the discharge port when the drive is turned on, the pulverized matter that has been caught can be pushed away to the discharge port.
Therefore, in the soot treating apparatus of the present invention, soot having a long fiber can be discharged without clogging at the inlet of the discharge port or at the trap portion connected to the discharge port, and in a relatively short time. It can be crushed and discharged. That is, in the soot treating apparatus of the present invention, the pulverized product discharge concentration per unit time can be reduced, and the time required for the pulverization and discharge process can be shortened.

Further, according to the invention described in claim 2, after the intermittent operation O1, the continuous operation O2 for continuously driving the drive unit for a predetermined time is performed.
In the present invention configured as described above, in the initial stage of pulverization in which a large amount of soot having a long fiber remains in the pulverization chamber, the intermittent operation O1 is performed and discharged at a low pulverized product discharge concentration. It is possible to prevent entanglement in a lump at the inlet of the outlet or at the trap portion connected to the outlet.
Then, as the remaining amount in the pulverization chamber of the soot having long fibers decreases due to the intermittent operation O1, the risk of being discharged at a high pulverized product discharge concentration decreases, so that the continuous operation after the amount of soot in the pulverization chamber has decreased to some extent By performing O2, the pulverizing and discharging process can be completed efficiently in a short time.
Therefore, in the soot treating apparatus of the present invention, soot having a long fiber can be discharged without clogging at the inlet of the discharge port or at the trap portion connected to the discharge port, and pulverized in a shorter time. Discharge can be processed.

Further, according to the invention described in claim 3, after the continuous operation O2, an intermittent operation O3 is performed in which the drive unit is intermittently driven for a predetermined time.
In the present invention configured as described above, in the initial stage of pulverization in which a large amount of soot having a long fiber remains in the pulverization chamber, the intermittent operation O1 is performed and discharged at a low pulverized product discharge concentration. It is possible to prevent entanglement in a lump at the inlet of the outlet or at the trap portion connected to the outlet.
Then, by performing the continuous operation O2 after the amount of soot in the grinding chamber has been reduced to some extent by the intermittent operation O1, it is possible to prevent discharging at a high pulverized product discharge concentration and to efficiently perform the pulverization discharge processing in a short time. it can.
Furthermore, by performing the intermittent operation O3 after the continuous operation O2, even when there is a pulverized product that has been stuck due to being caught at the inlet of the discharge port, the catch is eliminated when the drive of the drive unit is OFF. When the drive of the next drive unit is turned on, the pulverized matter that has been caught can be pushed away to the discharge port by instantaneously increasing the flow rate of the drainage to the discharge port.
Therefore, in the soot treating apparatus of the present invention, when crushing soot having a long fiber, it is possible to reliably prevent clogging occurring at the inlet of the discharge port or at the trap portion connected to the discharge port. Crushing and discharging can be performed in a short time.

According to the fourth aspect of the present invention, the impeller is disposed in the radial direction of the rotating plate, and the impeller outer end that is one end closer to the outer periphery of the impeller rotating plate is connected to one end closer to the center of the impeller rotating plate. It is characterized in that it is provided at a position retracted with respect to the rotation direction of the rotating plate from the inner end of the impeller.
In this invention comprised in this way, the direction which an impeller pushes out the waste_water | drain or pulverized material of a drainage part can be made into the radial direction of a rotating plate.
Usually, the drain outlet is often arranged in the radial direction of the drainage section. Therefore, by adopting the above configuration, the flow rate of the drainage to the discharge port can be further increased. In addition, even when the drive of the intermittent operation drive is OFF, the direction of pushing out the pulverized material is the radial direction of the rotating plate, so that the flow rate of drainage to the discharge port can be kept above a certain flow rate, and the efficiency It can be discharged in a short time.
Moreover, when switching the drive of the drive part of intermittent operation from OFF to ON, the flow rate of the waste water to the discharge port can be further increased instantaneously.
Therefore, even if there is a pulverized product that is stuck at the inlet of the discharge port, the catch is resolved when the drive unit is turned off, and the next drive unit drive is turned on to the discharge port. By instantly increasing the flow rate of the waste water, the crushed material that has been caught can be swept away into the discharge port.
Therefore, in the soot processing device of the present invention, the pulverized material can be efficiently discharged during intermittent operation.

According to the fifth aspect of the present invention, either the ON time width T1 or the OFF time width T2 or the ON time widths T1 and OFF in at least a part of the period during which the intermittent operations O1 and 03 are performed. Both time widths T2 vary.
In the present invention configured as described above, since the ON time and OFF time of intermittent operation can be changed, the ON time and OFF time can be optimized in the intermittent operations O1 and 03.
For example, in the period of intermittent operation, as the remaining amount in the pulverization chamber of the soot having long fibers decreases, the risk of being discharged at a high pulverized product discharge concentration decreases, so the ON time is longer than the initial pulverization, By shortening the OFF time, the pulverizing and discharging process can be efficiently performed in a short time.
Therefore, in the soot processing apparatus of the present invention, the pulverized product can be efficiently discharged during intermittent operation, so that the pulverization and discharge process can be performed in a shorter time.

Further, according to the invention described in claim 6, the water supply amount per unit time is increased or decreased in accordance with the operation status of the dredger treatment device in at least a part of the period in which water is supplied from the water supply unit. To do.
In this invention comprised in this way, the amount of water supply can be optimized by increasing / decreasing the amount of water supply from the water supply part.
For example, in the initial stage of pulverization, where the remaining amount in the pulverization chamber with long fibers is large, the water is discharged at a low pulverized product discharge concentration by increasing the amount of water supplied per unit time, and is discharged to the discharge port or to the discharge port. It is possible to prevent the pulverized material from being entangled in a lump in the trap part to be connected. And as the remaining amount in the pulverization chamber of the cocoon with long fibers decreases, there is no risk of being discharged at a high pulverized product discharge concentration, so by reducing the amount of water supply per unit time in the middle and later stages of pulverization This can prevent wasteful use of water.
Therefore, in the soot processing apparatus of the present invention, it is possible to prevent clogging at the inlet of the discharge port or at the trap part with a small amount of water used.

According to the invention of claim 7, in at least a part of the period of intermittent operation, rotating the rotating plate forward at a certain ON time and reversing the rotating plate at the next ON time, It is characterized by repeating at least once.
In the present invention configured as described above, the rotation of the rotating plate during intermittent operation can be forward, stopped, and reverse, so that the rotation plate is caught by the inlet of the discharge port during the normal rotation. Even if there is pulverized material that has been crushed, by eliminating the catch when the rotation of the rotating plate stops, by changing the flow direction of the drainage to the discharge port when the rotation of the next rotating plate is reversed The crushed material that has been caught can be easily washed away to the discharge port.
Moreover, the crushing discharge process can be efficiently performed in a short time by eliminating the clogging generated at the inlet of the discharge port.
Therefore, in the soot treating apparatus of the present invention, when the soot having a long fiber is pulverized, the clogging generated at the inlet of the discharge port can be surely eliminated, and the pulverizing and discharging process can be performed in a shorter time. it can.

According to the eighth aspect of the present invention, during at least a part of the period during which intermittent operation is performed, the rotating plate is normally rotated at a certain ON time, and then the rotating plate is reversed to shift to the OFF time. This is characterized in that it is repeated at least once.
In the present invention configured as described above, since the rotation of the rotating plate during the ON time during intermittent operation can be rotated forward and reverse, the pulverized material is placed at the inlet of the discharge port during the normal rotation of the rotating plate. Even when it is about to catch, the pulverized material that was about to be caught can be easily swept away to the discharge port by changing the flow rate direction of the drainage to the discharge port when the rotation of the rotating plate is reversed. .
Further, by preventing clogging that occurs at the inlet of the discharge port, the pulverization and discharge process can be efficiently performed in a short time.
Therefore, in the soot processing apparatus of the present invention, when the soot having a long fiber is pulverized, it is possible to reliably prevent clogging occurring at the inlet of the discharge port and to perform the pulverizing and discharging process in a shorter time. it can.

  According to the soot treating apparatus of the present invention, soot having a long fiber can be discharged without clogging at the inlet of the discharge port or at the trap portion connected to the discharge port, and pulverized in a relatively short time. Discharge can be processed.

A wrinkle processing apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a longitudinal sectional view of a soot processing apparatus according to a first embodiment of the present invention.
The main body of the soot processing apparatus has a crushing chamber 3 communicating with an input port 2 provided at the bottom of the sink 1, so that the soot can be put into the crushing chamber 3 from the input port 2. Is provided with a detachable drain lid (not shown).
On the upper surface of the rotating plate 4 provided at the bottom of the crushing chamber 3, hammers 5 are attached to two places so as to be capable of rotating. And the motor part 6 provided in the lower part of the grinding | pulverization chamber has a structure which rotates the rotating plate 4 with the signal from the motor control part 7. FIG.
The motor unit 6 is an AC motor, and the rotational speed of the motor unit 6 is provided from about 1500 to about 1800 times per minute. Further, since there is a possibility that electrical noise may be generated by switching ON / OFF of driving of the motor unit 6, the motor control unit 7 is provided with a snubber circuit (not shown) that suppresses electrical noise. ing.
A fixed blade 8 having a concavo-convex shape on the surface is provided on the inner periphery of the crushing chamber 3 located outside the rotating plate 4.
As a result, the soot introduced into the crushing chamber 3 from the inlet 2 is struck by the hammer 5 by the rotation of the rotating plate 4 and collides with the fixed blade 8 to be crushed. The crushed soot is discharged to the discharge portion 9 through the clearance between the fixed blade 8 and the outer periphery of the rotating plate 4.

The discharge portion 9 provided at the bottom of the crushing chamber 3 has a discharge port 10, and a trap portion 11 is connected to the discharge port 10. The trap portion 11 has an S-shape and is connected to a horizontal pipe (not shown) so that the crushed soot can be discharged.
The trap portion 11 has an S-shape having an inner diameter of about 32 mm and a relatively large curvature. This is to improve the fluidity when the crushed soot passes through the trap portion 11.
Further, an impeller 12 is attached to the lower surface of the rotating plate 4, and the drainage of the discharge unit 9 and the crushed soot are pushed to the discharge port 10 by the rotation of the rotating plate 4.

The water supply unit 20 has a water supply valve of a first water supply valve 13 and a second water supply valve 14 made up of electromagnetic valves, and is switched on / off by a signal from the water supply control unit 15 to supply a water supply pipe (Fig. It is an automatic water supply system that increases or decreases the amount of water supply per unit time from (not shown).
The water supply unit communicates with a water supply port 16 provided in the crushing chamber, and can supply water directly into the crushing chamber 3. Therefore, noise generated when water is supplied to the crushing chamber 3 can be prevented from propagating to the outside by the drainage lid, and the quietness can be improved.
By such an automatic water supply method, it is possible to prevent the deterioration of the discharge performance due to the shortage of the water supply amount per unit time and to discharge reliably.

FIG. 2 is a front view of the lower surface of the rotating plate 4 according to the first embodiment of the present invention.
In FIG. 2, the impeller 12 provided so as to be disposed in two places in the radial direction of the rotating plate 4 includes an impeller outer end 101 which is one end closer to the outer periphery of the rotating plate 4 of the impeller 12, and the rotating plate of the impeller 12. The impeller inner end 102, which is one end closer to the center of 4, is provided at a position retracted in the rotational direction of the rotating plate 4.
The impeller outer end 101 is located in the vicinity of the outer periphery of the rotating plate 4, and is a straight line connecting the approximate center of the rotating plate 4 and the impeller outer end 101, and a straight line connecting the impeller outer end 101 and the impeller inner end 102. The impeller mounting angle, which is an angle formed by the above, is provided at about 45 degrees.
Thus, by setting the impeller attachment angle to about 45 degrees, the direction in which the impeller 12 pushes out the drainage or pulverized material of the discharge portion 9 can be set to the radial direction of the rotating plate 4 and to the discharge port 10. The flow rate of the drainage can be increased, and even when the motor unit 6 in the intermittent operation is turned off, the flow rate of the drainage to the discharge port 10 can be maintained at a predetermined flow rate or more, and can be efficiently discharged. it can.
Further, the impeller 12 is provided substantially perpendicular to the rotating plate 4. Accordingly, it is possible to prevent the pulverized product from being sandwiched between the impeller 12 and the rotating plate 4, and to increase the force of the impeller 12 to push out the drainage or pulverized product.
The length of the impeller 12 is set to about 50% with respect to the radius of the rotating plate 4. Since the impeller 12 pushes the drainage and the pulverized product by the length of the impeller 12, the impeller 12 is preferably at least about 10% with respect to the radius of the rotating plate 4.

3 is a cross-sectional view taken along the line AA ′ of FIG. 2, which is a front view of the lower surface of the rotating plate 4 according to the first embodiment of the present invention.
In FIG. 3, the impeller 12 is provided on the lower surface of the rotating plate 4 in a substantially rectangular shape extending downward.

FIG. 4 shows an operation program according to the first embodiment of the present invention.
In FIG. 4, the horizontal axis is time, the left vertical axis is ON / OFF of driving of the motor unit 6, the right vertical axis is water supply amount per unit time, the upper program is driving the motor unit 6, and the lower program is water supply amount. Indicates increase or decrease.
ON / OFF of driving of the motor unit 6 is performed by intermittent operation in which ON 2 seconds and OFF 2 seconds are repeated 8 times, then ON 15 seconds is continuously operated, and finally ON 1 second is repeated twice. Is provided.
Further, the amount of water supplied per unit time is set to increase at the initial stage of pulverization and after the completion of pulverization.
In this way, by increasing the amount of water supply per unit time in the initial stage of pulverization, even when pulverizing soot that is relatively easy to pulverize, the discharge concentration in the initial stage of pulverization can be reduced, and the discharged pulverized It is possible to prevent the possibility that an object is stagnated in a horizontal pipe (not shown) and the pipe is blocked.
Further, by increasing the amount of water supplied per unit time after the pulverization is completed, it is possible to reliably prevent the discharged pulverized product from staying in the horizontal pipe (not shown).
By such an operation program, the pulverization and discharge processing time can be reduced to 60 seconds or less. The pulverization and discharge processing time in the cocoon processing apparatus is more convenient when it is shorter, and is preferably within 60 seconds at the longest.
In order to notify the user that the crushing and discharging process has been completed, when the crushing and discharging process is completed, a buzzer sound generating device (not shown) is activated by a signal from the motor control unit 7 to generate a buzzer. Sound may be generated.

  According to the soot treating apparatus of the present invention, soot having a long fiber can be discharged without clogging at the inlet of the discharge port 10 or at the trap portion 11 connected to the discharge port 10 and relatively short. It can be crushed and discharged in time.

FIG. 5 is a schematic diagram showing the discharge characteristics of the soot processing apparatus according to the present invention over time.
In FIG. 5, in addition to the “intermittent operation with the impeller” of the present invention, the pulverized product discharge concentration with respect to the passage of time of “continuous operation”, “continuous operation with the impeller” and “intermittent operation” is schematically illustrated. It is represented.

In “continuous operation” in FIG. 5, since the motor unit 6 is continuously driven, a large amount of soot is pulverized in a short time in the initial operation.
Therefore, the pulverized product discharge concentration reaches a peak at the initial stage of pulverization, and the pulverized product discharge concentration at the peak increases.

In “continuous operation provided with an impeller” in FIG. 5, the impeller 12 pushes out the drainage or pulverized material of the discharge unit 9 by the rotation of the rotating plate 4, and the flow rate of drainage to the discharge port 10 increases.
Therefore, the pulverized product discharge concentration reaches a peak earlier than the “continuous operation”, and the pulverized product discharge concentration at the peak increases.

In the “intermittent operation” of FIG. 5, the motor unit 6 is driven intermittently, so that the discharge amount per unit time becomes small. And when the drive of the motor part 6 is OFF, since the flow velocity to the discharge port 10 is small, the pulverized product discharge concentration decreases.
Moreover, since it grind | pulverizes by an intermittent operation, the time required for grind | pulverizing all the soot in the grinding | pulverization chamber 3 increases.

In the “intermittent operation with an impeller” of the present invention shown in FIG. 5, the motor unit 6 is driven intermittently, so that the discharge amount per unit time is reduced.
Since the impeller 12 extending downward is provided on the lower surface of the rotating plate 4, the impeller 12 pushes out the drainage or pulverized material of the discharge unit 9 by the rotation of the rotating plate 4, and the flow rate of drainage to the discharge port 10 increases. . Therefore, even when the driving of the motor unit 6 in the intermittent operation is OFF, the flow rate of the drainage to the discharge port 10 can be maintained at a predetermined flow rate or more, and the pulverized material in the discharge unit 9 can be discharged to the discharge port 10.
That is, the pulverized material discharged to the discharge unit 9 can be discharged not only when the motor unit 6 in intermittent operation is turned on but also when it is turned off, so that the pulverization and discharge process can be performed in a relatively short time. .
Further, since the impeller 12 is provided when switching the driving of the motor unit 6 in the intermittent operation from OFF to ON, the flow rate of drainage to the discharge port 10 can be instantaneously increased. Therefore, even when there is a pulverized product that is stuck at the inlet of the discharge port 10 when the drive of the motor unit 6 is ON, the catch is eliminated when the drive of the motor unit 6 is OFF, and the next When the drive of the motor unit 6 is ON, the pulverized matter that has been caught can be pushed away to the discharge port 10 by instantaneously increasing the flow rate of the drainage to the discharge port 10.
Therefore, in the “intermittent operation with the impeller” of the present invention, the pulverized product discharge concentration can be maintained for a certain period while being relatively small, and the time required for the pulverization discharge process can be shortened.

The water supply unit 20 according to the first embodiment of the present invention is an automatic water supply system that supplies water directly to the water supply port 16 provided in the crushing chamber, but water is supplied from a water supply means (not shown) provided in the upper part of the sink 1. It is possible to use a manual water supply method in which water is supplied into the crushing chamber 3 through a drain lid water supply port provided in the drain lid.
Such an automatic water supply system is economical because water supply means used in water work at the sink 1 can be used, and it is not necessary to provide a separate water supply means.

Although the water supply part 20 by 1st embodiment of this invention is an automatic water supply system, the water supply part 20 may be a manual water supply system.
That is, a method of controlling ON / OFF of water supply and the amount of water supply per unit time manually by a water supply means (not shown) provided in the upper part of the sink 1 may be used. In such a case, water is supplied to the crushing chamber 3 from a drain lid water supply port provided in a drain lid (not shown).

The rotating plate 4 according to the first embodiment of the present invention is provided with an impeller attachment angle of about 45 degrees, but may be provided with an impeller attachment angle of about 0 degrees.
FIG. 6 shows a front view of the lower surface of the rotating plate 4 provided with an impeller attachment angle of about 0 degrees.
In FIG. 6, the impellers 12 provided at two locations are an impeller outer end 101 that is one end of the impeller 12 near the outer periphery of the rotating plate 4 and an impeller inner end 102 that is one end of the impeller 12 near the center of the rotating plate 4. Are provided at positions that coincide with the rotation direction of the rotating plate 4.
FIG. 7 is a cross-sectional view taken along the line AA ′ of FIG. 6, which is a front view of the lower surface of the rotating plate provided with an impeller attachment angle of about 0 degree.
In FIG. 7, the impeller 12 is provided on the lower surface of the rotating plate 4 in a substantially rectangular shape extending downward.

The impeller 12 is attached to the rotating plate 4 according to the first embodiment of the present invention at two locations, but the impeller 12 may be attached to three or more locations.
FIG. 8 shows a front view of the lower surface of the rotating plate 4 with the impellers 12 attached at three locations.
In FIG. 8, the impeller 12 provided at three locations has an impeller outer end 101 which is one end of the impeller 12 near the outer periphery of the rotating plate 4 and an impeller inner end 102 which is one end of the impeller 12 near the center of the rotating plate 4. Rather, it is provided at a position retreating with respect to the rotation direction of the rotating plate 4, and is provided in a shape that swells on the outer periphery of the rotating plate 4 from the impeller outer end 101 to the impeller inner end 102.
FIG. 9 is a cross-sectional view taken along line AA ′ of FIG. 8, which is a front view of the lower surface of the rotating plate 4 with the impellers 12 attached at three locations.
In FIG. 9, the impeller 12 is provided in a substantially trapezoidal shape that extends downward on the lower surface of the rotating plate 4.

In addition to the operation program according to the first embodiment of the present invention, the following operation program may be used.
FIG. 10 shows another example of the operation program of the present invention.
In FIG. 10, ON / OFF of the drive of the motor unit 6 is an intermittent operation in which ON 2 seconds and OFF 2 seconds are repeated 5 times, then an intermittent operation in which ON 3 seconds and OFF 2 seconds are repeated 3 times, and then ON 10 2 seconds of continuous operation, and finally intermittent operation that repeats ON 1 second twice.
Further, the amount of water supply per unit time is provided to increase only in the initial stage of pulverization.
As described above, by shortening the ON time in the initial stage of pulverization, discharge of the pulverized material having a high concentration can be prevented.

FIG. 11 shows another example of the operation program of the present invention.
In FIG. 11, ON / OFF of the driving of the motor unit 6 is an intermittent operation in which ON 1 second and OFF 3 seconds are repeated three times, then ON 2 seconds and OFF 2 seconds are repeated five times, and then ON 10 2 seconds of continuous operation, and finally intermittent operation that repeats ON 1 second twice.
Further, the amount of water supply per unit time is set to increase after the pulverization is completed after the water supply is stopped for the first 5 seconds of the continuous operation.
Thus, by shortening the ON time and lengthening the OFF time at the initial stage of pulverization, it is possible to prevent the pulverized material having a higher concentration from being discharged. In addition, by stopping the water supply during the first 5 seconds of continuous operation, grapes such as grapefruit peel that is light in specific gravity and floats in the crushing chamber 3 and is not easily crushed can be crushed.

FIG. 12 shows another example of the operation program of the present invention.
In FIG. 12, ON / OFF of the drive of the motor part 6 performs intermittent operation which repeats ON 3 seconds and OFF 2 seconds 5 times, and then performs ON 20 second continuous operation.
In addition, the amount of water supply per unit time is set to increase at the initial stage of pulverization and at the end of pulverization.
Thus, the durability of the relay of the motor control unit 7 can be improved by reducing the number of times of ON / OFF switching. Considering the durability of the relay, it is desirable that the number of ON / OFF switching be about 10 times or less.

FIG. 13 shows another example of the operation program of the present invention.
In FIG. 13, ON / OFF of the drive of the motor unit 6 performs an intermittent operation in which ON 2 seconds and OFF 2 seconds are repeated 15 times.
Further, the amount of water supplied per unit time is set to increase at the initial stage of pulverization and after the completion of pulverization.
In this way, by performing only intermittent operation, it is possible to reliably prevent clogging of the inlet of the discharge port 10 or the trap portion 11.

FIG. 14 shows another example of the operation program of the present invention.
In FIG. 14, the horizontal axis is time, the left vertical axis is normal rotation / reverse rotation / off of the motor unit 6, the right vertical axis is the amount of water supply per unit time, the upper program is the motor unit 6 drive, and the lower is the water supply Indicates volume increase or decrease.
In FIG. 14, ON / OFF of the drive of the motor part 6 performs intermittent operation which repeats ON 2 seconds and OFF 2 seconds 15 times. The rotation of the rotating plate when the drive of the motor unit 6 is turned on alternately performs forward rotation and reverse rotation.
Further, the amount of water supplied per unit time is set to increase at the initial stage of pulverization and after the completion of pulverization.
As described above, the rotation of the rotating plate 4 when the driving of the motor unit 6 is turned on is alternately performed in the normal direction and the reverse direction, so that the clogging generated at the inlet of the discharge port 10 can be surely eliminated and further shortened. It can be crushed and discharged in time.

FIG. 15 shows another example of the operation program of the present invention.
In FIG. 15, ON / OFF of the drive of the motor part 6 performs intermittent operation which repeats ON 2 seconds and OFF 2 seconds 15 times. When the motor unit 6 is turned on, the rotation of the rotating plate 4 is normal rotation in the first half and reverse rotation in the second half.
Further, the amount of water supplied per unit time is set to increase at the initial stage of pulverization and after the completion of pulverization.
In this way, by performing forward and reverse rotations of the rotating plate 4 when the driving of the motor unit 6 is ON, it is possible to reliably prevent clogging occurring at the inlet of the discharge port 10 and in a shorter time. It can be crushed and discharged.

The ON time, OFF time, forward rotation time, and reverse rotation time for driving the motor unit 6 in FIGS. 10 to 15 are examples, and needless to say, other than these may be considered.
Similarly, the water supply amount per unit time in FIGS. 9 to 14 is also an example, and it goes without saying that it is possible to consider other than these.

In the first embodiment of the present invention, the motor unit 6 is an AC motor, but may be a DC motor.
In that case, it is desirable to control the grinding performance by continuously changing the rotational speed of the motor unit 6.

  In the first embodiment of the present invention, the trap portion 11 is provided in an S shape, but may be provided in a P shape.

In the first embodiment of the present invention, intermittent operation for intermittently driving the motor unit 6 is performed. However, it is desirable that the rotating plate 4 is completely stopped when the intermittent operation is OFF.
This is because the flow rate of the drainage to the discharge port 10 can be greatly changed by turning on after the rotating plate 4 is completely stopped, and the clogging generated at the entrance of the discharge port 10 can be reliably eliminated or prevented. Because you can.

In the first embodiment of the present invention, intermittent operation is performed in which the motor unit 6 is intermittently driven. However, in addition to intermittent operation, when the displacement amount per unit time of driving of the motor unit 6 is large. Needless to say, there are similar effects.
For example, in the case of using a DC motor, if the rotational speed is changed from 1500 times per minute to several times per minute, the amount of displacement of the rotational speed is large, so the flow rate of drainage to the discharge port 10 is greatly changed. Thus, clogging occurring at the inlet of the discharge port 10 can be reliably eliminated or prevented.
