Research Advance on the Drying Section of Paper Machine

The drying section of paper machine is not only the major energy-consuming parts of the papermaking process, but also one of the main bottleneck restricting the speed, yield and paper quality. So the research on the drying section has attracted much attention at home and abroad. In view of the traditional steam dryer shortcomings, this paper first introduces two kinds of improvement measures —— the tubulator bar and the siphon which can improve the efficiency of the traditional steam dryer. With the development of the paper industry, domestic and international research on the new type of paper drying technology has achieved some success. Then, we analyse their working principle and characteristic, and conclude that multi-channel dryer has a broad research and application prospects.
