Next, the operation will be described. When the lid 32 is opened, the inside of the processing tank 4A divided by the partition plate 36 can be seen from the input port 28. A shown in FIG.
Is a standard level for input of garbage 3, and B is an appropriate processing level.

When the lid 32 is closed after the garbage 3 is thrown in, the limit switch 68 detects this, and an operation command of the operation switch 140 is accepted on condition of this detection.
The motor 22 is rotated based on the operation command, and the garbage 3 is moved from the processing tank 4A to the processing tank 4B by the scrapers 18, 18A and 18B from the window 38 below the partition plate 36. As a result, the garbage 3 in the processing tank 4 is leveled to the appropriate processing level B as shown in FIG. That is, even if the garbage 3 changes to a clay state as a result of heating and stirring, the load applied to the motor 22 is small, the garbage 3 is efficiently stirred, and the heat from the heater 6 is uniformly applied to the garbage 3. And its drying is accelerated. In this case, the motor 2
2 is to reverse the rotation direction at regular time intervals, thereby changing the stirring direction alternately, thereby removing the garbage 3 from the treatment tank 4.
The garbage 3 is moved alternately between A and 4B, and the crushing and stirring of the garbage 3 can be performed simultaneously by the contact between the partition plate 36 and the scrapers 18A and 18B. Therefore, the garbage 3 can be dried as quickly as possible.

As shown by the solid line in FIG. 2, when the garbage 3 is put into the treatment tank 4A, even if the garbage 3 reaches the level D which greatly exceeds the standard level A, there is the treatment tank 4B.
The garbage 3 is leveled below the processing upper limit level C, and does not become overloaded as in the prior art. That is, the motor 22 can be protected from an excessive load, and the heating and drying of the garbage 3 can be promoted.

The crushing of solids will be described. As shown in FIG. 5, the garbage 3 scraped up by the scrapers 18, 18A, 18B is separated from the inner edge of the window 38 of the partition plate 36 by the scrapers 18A, 18B. It is crushed by being sandwiched between. The solids and fibers are finely crushed by the crushing by the partition plate 36, and the heating and drying can be promoted. The window portion 38 of the partition plate 36 is formed in a step shape, and reduces the load on the motor 22 when the food waste 3 is divided and crushed. The same effect can be expected even if the edge of the window 38 is formed in a tapered shape.

If crushable foreign substances such as cloth and bone are caught between the scrapers 18A and 18B and the partition plate 36 when the garbage 3 is crushed, the rotation is stopped. this is,
When the rotation number is detected by the rotation detector 70 and the number of rotations falls below a predetermined value, it is determined that crushing by the foreign matter is impossible, and the rotation of the motor 22 is reversed to remove the foreign matter that is biting. If the rotation state does not return to normal even after several rotations of the rotation direction within the predetermined time, the operation of the motor 22 and the heater 6 is stopped, and the state is displayed on the display 160 to the user. , The operation of the buzzer 164.

FIG. 6 shows a control operation of the drying process.

As shown in FIG. 6, step S1 is a routine for putting the garbage 3 into the processing tank 4 and starting the heating and drying process. That is, the lid 32 is opened, and the garbage 3 is placed in the treatment tank 4.
Put into A. After confirming that the input level of the garbage 3 is below the standard level A, the lid 32 is closed. When the closed state of the lid 32 is detected by the limit switch 68, an input from the operation switch 140 is accepted.

In step S2, the heater 6, the motors 22, 50, and 154 start driving according to the input of the operation switch 140, and perform a drying process. The garbage 3 is stirred and crushed by the drive of the motor 22, and the moisture is evaporated by heating by the heater 6. The air in the processing tank 4 is circulated through the pipeline 40, the heat exchanger 44, and the pipeline 42 by the fan 52. Water condensed by the air cooling of the heat exchanger 44 is discharged to a drain pipe 56.
Is discharged to the outside. In addition, water 6
Zeros accumulate, shut off the outside world and the processing tank 4, and seal off the unusual odor generated when the garbage 3 is heated in the processing tank 4.

Step S3 is a routine for confirming whether or not the drying is completed based on whether or not the heating process proceeds and the temperature difference detected by the temperature sensors 64 and 66 is equal to or more than a predetermined value. When the evaporation of water from the garbage 3 is completed, the temperature sensor 6
4, the detected temperature of the temperature sensor 66 decreases. When the temperature difference becomes equal to or more than the predetermined value, the process proceeds to step S4 as drying is completed, and the operation of the heater 6 is stopped.

In step S5, the processing tank 4 and the heat exchanger 44
This is a routine for confirming whether or not the ambient temperature of the air circulating through has decreased to a predetermined temperature. By cooling the atmosphere temperature of the processing tank 4, it is possible to suppress an unpleasant odor generated when the garbage 3 is dried and to prevent a rise in hot air when the lid 32 is opened. It is confirmed that the temperature detected by the temperature sensor 64 has dropped to a predetermined temperature, and the process proceeds to step S6.
Move to In addition to the temperature drop, it may be determined that a predetermined time has elapsed since the heater 6 was stopped.

In step S6, the motors 22, 50 and 154 are stopped, assuming that the heating and drying process has been completed. Subsequently, the process proceeds to step S7, and the end of the drying process is notified to the user through the display 160 or the buzzer 164.

Next, FIG. 7 shows a control operation in the case where solids cannot be crushed.

Step S10 is a routine in which the heating and drying process of the garbage 3 is started, and the motor 22 is rotated forward and backward at predetermined time intervals to stir and crush the garbage 3. That is, it is a routine for executing the flowchart shown in FIG. In step S11, it is determined whether or not a predetermined time has elapsed since the occurrence of the foreign matter biting abnormality. If the predetermined time has elapsed, the process shifts to step S12 to clear the count value and the time measurement. That is, the count values and time counts of steps S14 and S15 in the previous routine are cleared.

Step S13 is a routine for determining whether or not the rotation speed detected by the rotation detector 70 is abnormal, that is, whether or not the rotation speed is lower than the predetermined rotation speed and a load is generated due to biting of foreign matter. It is. If the rotation is not abnormal (NO), the process proceeds to step S10, and the normal / reverse rotation control of the motor 22 is executed. When a rotation error occurs (YE
In S), the process proceeds to step S14.

In step S14, the number of times of occurrence of abnormality is counted. In step S15, time measurement is started based on the first occurrence of abnormality. In step S16, the motor 2
2 is reversed to release the bite of the foreign matter.

In step S17, it is determined whether N abnormalities have been detected. When no abnormality is detected N times (N
In O), the process proceeds to step S10, and when the occurrence of an abnormality is detected N times (YES), the scrapers 18A, 18B
And that there is a foreign matter that cannot be crushed by the partition plate 36,
Move to step S18. In step S18, the operation is stopped, and the user is informed of the removal of the foreign matter by the display 16.
0, notification by buzzer 164.

In the embodiment, the case where the processing tank 4 is partitioned by one partition plate 36 has been described.
The treatment tank may be partitioned into more than tanks, or the treatment tank may be partitioned vertically.
