PROBLEM TO BE SOLVED: To efficiently give automatic drying treatment to various dried objects. SOLUTION: In a charging process for charging the dried objects 11 into a drying chamber 18, an agitating blade 32 is controlled to be rotationally driven at a preset constant target speed until load torque exceeds preset threshold torque PS. Then, when the load torque exceeds the threshold torque PS, a transition is made to a drying process for heating and drying the charged dried objects 11 being agitated. In the drying process, the driving toque of the agitating blade 32 is increased until reaching preset constant target torque T1 and then a constant torque control mode is executed for rotational drive to maintain the target torque. When load is reduced with the progress of a drying degree to establish the condition of drive with torque not higher than the target torque, a transition is made to a crushing process for crushing the dried objects into small dried pieces. In the crushing process, the agitating blade is controlled to be rotationally driven at a preset constant crushing speed. COPYRIGHT: (C)2006,JPO&NCIPI
