The Drying Section Of Paper Machine
In traditional drying, a single-layer dryer structure (UNORUN device), usually near the wet end, can reduce the jitter of the paper web and avoid paper diseases such as “paper pores” as much as possible. Between the paper sheet and the cylinder surface, the productivity of the lower dryer cylinder is lost.
Influencing Factors For Drying

3. Dry blanket structure, air permeability, and tensile resistance: 20%
4. Bag area ventilation: 15%
5. Dryer cover and dryer air system: 5%
6. Other: 5%
