PROBLEM TO BE SOLVED: To stably obtain a dehydrated material of a set low moisture content in a continuous rotary type pressure dehydration apparatus. SOLUTION: The continuous rotary type pressure dehydration apparatus 10 equipped with a plurality of channels 100 is provided with a back pressure plate 109 in an outlet 107 of each of the respective channels 100, and is provided with a sensor for detecting the inlet pressure or outlet pressure of each channel 100 or the moisture content of the dehydrated cake W discharged therefrom. The pressure is relaxed by opening the back pressure plate 109 when the pressures exceed the prescribed values. Relating to the channel which is once relaxed in the pressure, the similar control is thereafter repetitively performed at every other prescribed time. COPYRIGHT: (C)2006,JPO&NCIPI
