As shown in FIG. 6, on the “automatic monitor screen” 70, the actual operating condition of each part of the stirring and crushing unit 2 is displayed on the screen. That is, the liquid crystal display 36 displays which step of the plurality of steps is being executed, and also displays the remaining operation time at the step being executed. When the additive supply process is being executed, the liquid crystal display 36 displays that the additive supply process is being executed and the remaining time of the process. Further, in the liquid crystal display 36, whether or not the lid sensor 18 is turned on and the lid 6B is properly closed, whether or not the vacuum pump 25, the vacuum valve 26, the open valve 27, etc. are in proper operating states, etc. Displays various operating states of. Therefore, the liquid crystal display 36 constitutes a display means for displaying the actual operating state.

  When the start switch 38 is pressed, the control device 3 first starts the operation of the vacuum pump 25 and switches the vacuum valve 26 to the open state. As a result, the pressure in the storage space 5 of the crushing container 6 is reduced. After that, the cutter motor 13 and the scraping motor 16 are rotated under the setting condition for each step set as described above to execute the stirring and pulverizing process. If the control device 3 is switched to the "automatic monitor screen" 70 during the stirring and crushing process, the liquid crystal display 36 displays the actual operating condition of each part of the stirring and crushing unit 2 as described above. Display with.

When the temperature of the object to be processed detected by the temperature sensor 17 exceeds the upper limit temperature T1 corresponding to the step during the stirring and pulverizing process, the control device 3 sounds the buzzer 42 to notify that. At the same time, the stirring and crushing process is stopped. This process corresponds to the temperature rise suppression process. That is, the rotations of the cutter motor 13 and the scraping motor 16 are stopped.
As a result, a further rise in temperature of the object to be processed is suppressed, and disadvantages such as an excessive increase in the viscosity of the object to be processed are avoided.

After the stirring and pulverizing process is stopped, when the temperature of the object to be processed falls to the return temperature T2, the operation of the stirring and pulverizing process can be restarted in response to the start command from the start switch 38.
This process corresponds to the return process. When the worker pushes the start switch 38 in this state, the control device 3 rotates the cutter motor 13 and the scraping motor 16 to restart the stirring and pulverizing process. When the agitating and pulverizing process is being executed, even if the temperature of the object to be treated does not exceed the upper limit temperature T1, when the stop switch 39 is pressed, the control device 3 stops the agitating and pulverizing process. After that, when the start switch 38 is pressed, the control device 3 restarts the stirring and crushing process.

  In the step in which the additive supply process is set, the control device 3 switches the additive supply valve 33 to the open state so that the additive (rice oil) stored in the storage tank 31 is stored in the crushing container 6. Supply. When such an additive supply process is being executed, the liquid crystal display 36 displays on the “automatic monitor screen” 69 that the additive supply process is being executed, and the remaining time of the process is displayed. indicate. When the set time has elapsed, the additive supply valve 33 is switched to the closed state, and the display indicating that the additive supply process is being executed is terminated.

  After starting the operation, the control device 3 causes the buzzer 42 to ring when the lid sensor 18 detects that the lid 6B is opened or when the emergency stop switch 41 is pushed. This is notified and the stirring and crushing process is stopped. After that, the reset switch 40 is pushed to stop the operation of the buzzer 42. In this case, since it is an abnormal operation, appropriate measures will be taken to shift to the next processing.

The control device 3 executes the stirring and crushing process for each of the plurality of steps and the additive supply process in the predetermined steps according to the set procedure, and when the stirring and crushing process in all the steps is completed, the operation of the vacuum pump 25 is started. After stopping, the vacuum valve 26 is closed and the open valve 27 is opened to return the storage space 5 of the crushing container 6 to the atmospheric pressure as the initial pressure. Then, the buzzer 42 is caused to ring, and the notification lamp 74 provided at a high position is turned on via the support column 73 to notify that fact.
The operator operates the reset switch 40 to stop the ringing of the buzzer 42, then releases the lock and opens the lid 6B.

[Discharge treatment]
Next, on the initial setting screen shown in FIG. 5, the “tank tilt mode command section” 71 is operated to switch to the “tank tilt operation command screen” 72. Although not shown, the "tank tilt operation command screen" 72 has a command part for commanding the tank tilt and a command part for commanding the tank return, and moves the crushing container 6 from the vertical posture to the sideways posture. It is possible to change the attitude and to change the attitude of the crushing container 6 from the sideways tilted attitude to the vertically oriented attitude.

In the tank tilt mode, the attitude of the crushing container 6 can be changed by operating the foot-operated tank tilt switch 23 and the tank return switch 24 described above. With the crushing container 6 switched to the sideways posture, the worker can discharge the object to be processed outward.
After the discharge is completed, the crushing container 6 is returned to the vertical posture and the work is completed.
