CIRCULATION DRYING DEVICE OPERATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a circulation drying device operating method for starting the spray of an dried object into a dryer without a great change in the temperature of gas in the outlet of the dryer and in the pressure of gas in a device. SOLUTION: The operating method is provided for a circulation drying device 10 which has a means for automatically adjusting the spray amount of latex or water so that the temperature of gas in the outlet of the dryer 14 reaches a set temperature. It comprises a step of spraying the water into the dryer 14 when starting the operation of the circulation drying device 10 in the state that the set temperature of the gas in the outlet of the dryer 14 is set higher than a set temperature in drying the latex until the temperature of gas in the inlet of the dryer 14 reaches the set temperature in drying the latex, and a step of setting the set temperature of the gas in the outlet of the dryer 14 to be the set temperature in drying the latex after the temperature of the gas in the inlet of the dryer 14 reaches the set temperature in drying the latex and then starting the spray of the latex instead of the water.
