HIGH-INTENSITY PAPER DRYING - A NEW AND P OSSIBLY LESS ENERGY-CONSUMING TECHNOLOGY FOR A STRONGER GRADE OF PAPER

A new drying technique is proposed for drying newsprint and other prin ting grades of paper. According to this technique, the wet web is pres sed onto the surface of at least two large-diameter cylinders heated t o approximately 120-degrees-C. These cylinders provide about half of t he drying heat. The other half of the energy is supplied by hot gas wh ich impinges on the paper from hoods surrounding the cylinders. Compar ed with the conventional cylinder method of drying, the new technique achieved a faster drying rate, and yielded paper with increased streng th and improved printing quality.
