  In the above-described conventional configuration, the crushing and crushing device as the stirring and crushing means is configured to continuously rotate at a high speed, so that when the temperature of the brown rice as the object to be processed rises and exceeds a predetermined temperature during the rotation operation, There was sometimes alpha. If the brown rice is turned into alpha, there is a risk that the viscosity increases and the driving load applied to the stirring and grinding means may be excessive, and the quality of the processed food to be produced is degraded.

  Therefore, it has been desired to avoid an increase in the temperature of the object to be processed when the stirring and grinding process by the stirring and grinding means is executed.

The characteristic configuration of the stirring and pulverizing apparatus according to the present invention is as follows:
A stirring and pulverizing means for stirring and pulverizing the workpiece; a control means for controlling the operating state of the stirring and pulverizing means; and a temperature detecting means for detecting the temperature of the object to be processed by the stirring and pulverizing means.
When the detected value of the temperature detecting means exceeds the set temperature for the rise determination, the control means executes a temperature rise suppressing process for suppressing a temperature rise of the object to be processed or a notifying process by a notifying means.

Thereby, the further temperature rise of the to-be-processed object is suppressed. Alternatively, instead of executing the temperature rise suppression process, the control means can perform the notification process, thereby notifying the operator of the temperature rise state. By the notification process, the worker can take measures to suppress the temperature rise of the workpiece.

When the temperature of the object to be processed is sufficiently lowered to be lower than the set temperature for the lowering determination, the stirring and grinding process can be resumed by executing the restoration process.

  Therefore, it is possible to avoid stopping the stirring pulverization process or continuing the reduced speed state of the stirring pulverization process for an unnecessarily long time. As the returning process, the stirring and grinding process may be automatically executed, or a notification process for prompting the operator to start operation may be executed.
