摘要
Abstract
Lycium barbarum polysaccharides with 20%moisture content were dried in a vacuum belt dryer. The moisture content and solution viscosity of the dried product were quality index in this investigation. The results show that the tempera-ture in the first heating area cannot be set too high so as to prevent the materials form losing too much. Otherwise,the re-duced thermal conductivity would influence the heat transfer from bottom to top in the material layer;the solution viscosity of the dried product would be reduced due to the higher temperature of the bottom material;while the moisture content of the dried product located on the top of the material layer would be higher because of the reduced heat transfer. In this experiment,the best operating parameters are 120,110,100,30,℃,and the operating pressure is 1,000,Pa. The results can be of great help to industrial production.关键词
