Drying cylinder main parts include: heat pump, the steam supply system, the condensed water recycling system, flash tank, differential pressure control system, pressure control system, flash tank, noncondensable exclude system, hot water pump, manual control program, the warm-up - paper - boot program system.
Drying principle of dryer
The saturated steam from the steam joint is condensed in the oven, and the heat released by the steam causes the temperature of the dryer to rise, which will heat the paper over the surface of the roller shell. Heat is transferred to the paper in contact with the surface of the paper and the dryer.
After releasing heat steam condensate produced a large number of condensed water, the condensed water because the rotation of the cylinder dryer attached by centrifugal force in the inner surface, form water ring under the condition of the angular velocity is higher, hindered the dryer to the surface of the heat transfer, so you need to siphon to condensed water discharge in a timely manner. When the speed is low, the water ring will not form, but there will also be the condensation of water in the dryer.
