Can be prevented from increasing, and a decrease in the activity of microorganisms can be prevented.

According to the third aspect of the present invention, the load state of the carrier is detected by detecting the number of revolutions of the stirrer, and based on the result, the drive of the stirrer is controlled to prevent unevenness of water in the carrier. As a result, the water content of the carrier can be prevented from increasing and the activity of microorganisms can be prevented from lowering.

According to the fourth aspect of the present invention, the load state of the carrier is detected by detecting the rotation speed of the stirrer, and based on the result, the driving of the heating means, the fan, and the stirrer is controlled to control the drive of the stirrer. Since unevenness of the water in the inside can be prevented and the water can be more easily evaporated, it is possible to prevent the water content of the carrier from being increased, and to more surely prevent the decrease in the activity of the microorganism.
