摘要
本文介绍笔者研制的一种并流式换向通风经济作物烘干机的结构与工作原理.实验结果表明,采用这种新工艺,与现行的烘干机类型相比,能缩短烘干时间,使烘后物料的含水量均匀,烘干质量高.同时,对物料的干燥速度和干燥时间提出了估算公式.
This paper gives an introduction to the development of concurrent flow drier with changing-direction ventilating for cash crops.The results of the tests showed using this new technique the drying time is shorter and drying quality better than previous driers.Cal- culation formulas of drying rate and time for material have been established also.
