The invention discloses a control method and device for a
water temperature of a regulation part of a cocoon cooking
machine. The cocoon cooking
machine comprises a steam inlet
pipe, a cold water inlet
pipe and drainage pipes. The invention is characterized in that the control on the
water temperature of the regulation part of a circular cocoon cooking
machine is divided into a high temperature zone, a
moderate temperature zone and a low temperature zone, the temperature is adjustable, 0.1-0.15% of surfactant is added into the regulation part according to the water amount, a drainage
pipe is mounted in each of the high temperature zone,
moderate temperature zone and low temperature zone, namely, a high-temperature zone drainage pipe, a moderate-temperature zone drainage pipe and a low-temperature zone drainage pipe are mounted in the high temperature zone,
moderate temperature zone and low temperature zone, respectively, the mounting positions are determined according to the opening of a steam
inlet valve of the regulation part and the
water temperature, or the opening of the drainage pipes, the steam flow of the steam inlet pipe and the
water flow of the cold water inlet pipe are adjustable. The invention skillfully controls the temperature at the desired process temperature by using relatively less
water flow, thus the working efficiency of operators is greatly improved, renditta is reduced, and reelability is increased.
