合江地区种子气流烘干室,目前基本采用单向供温直接或间接加热的形式。经过三年使用观察,发现在结构、保温、供热、节能和烘干质量等方面不够理想,弊病不少。1982年经过认真总结研究,在富锦县大榆树中心种子站建设一处双向供温余热回收气流烘干室,进行了改革试验。现将试验结果报告如下:一、双向供温余热回收气流烘干室结构1、操作室:设置热风炉、风机和电机。热风炉炉膛容积2.719立方米(长1.5米×宽1.25米×高 Hejiang area seed flow drying room, the current basic one-way direct or indirect heating of the heating form. After three years of observation, I found that there are not many drawbacks in terms of structure, heat preservation, heat supply, energy saving and drying quality. In 1982, after a careful summary of the research, a bidirectional temperature and waste heat recovery air drying room was constructed in the Great Yushu Central Seed Station in Fujin County, and a reform experiment was carried out. Now the test results are reported as follows: First, the two-way temperature and waste heat recovery air drying room structure 1, operating room: set hot stove, fan and motor. Stove hearth furnace volume of 2.719 cubic meters (length 1.5 meters wide and 1.25 meters high
