Process of controlling the temperature of a drying apparatus.

摘要

A process for controlling the temperature of a drying apparatus including a cylindrical rotor having a plurality of heating means which are independent of each other and arrayed in an advance direction of raw material, said process comprises controlling said heating means in response to measurements of the flow rate and moisture rate of the raw material charged into said rotor and the measurements of the temperatures of respective sections of the rotor each corresponding to each heating means so that the temperature of each section is changed in accordance with a flow rate characteristics curve of each section and controlling the heating means so that a bias temperature for compensating for the thermal response dead time of each heating means is applied prior to controlling for changing the temperature of each section in accordance with said flow rate characteristics curve by feed back controlling at least a final heating means in response to the measurement of the moisture rate of the dried raw material discharged from said rotor.
