Product Description

Product Description

The dryer cylinder is used as a key component for paper drying - Class I pressure vessels.The saturated steam introduced from the steam joint condenses inside the dryer, and released heat causes the temperature of the dryer cylinder to rise, thereby heating the sheet coated on the surface of the roll shell. Heat is transferred to the paper during contact between the paper and the dryer surface. The steam releases heat and condenses to produce a large amount of condensed water.
