中国农机院食品机械所承担的“七五”攻关项目粉料气流烘干机,于1990年10月31日通过部级鉴定。结论是:比耗蒸汽在气流干燥中处世界先进水平。该机采用正负压结合两级气流干燥,热风调节,全部回收废气利用余热,热效率80～88%;卸料简单、可靠,无粉尘,产品水分可按需调节。该机干燥能力1吨,蒸发水分490千克,风机耗电17千瓦小时,比耗蒸汽1.34千克。谈机适用于干食品、淀粉、饲料、医药、化工等行业的粉料和细颗粒料的干燥。
China Agricultural Machinery Institute of food machinery bear “75” research project powder air dryer, in October 31, 1990 through ministerial identification. The conclusion is: than the steam consumption in the air drying at the advanced world level. The machine uses positive and negative pressure combined with two air drying, hot air conditioning, waste heat recovery of all waste heat utilization, thermal efficiency 80 ~ 88%; unloading simple, reliable, dust-free, product moisture can be adjusted as needed. The machine drying capacity of 1 ton, 490 kg of evaporated water, fan power 17 kilowatt hours, than the steam consumption of 1.34 kilograms. Talking machine suitable for dry food, starch, feed, medicine, chemical and other industries powder and fine particles of material drying.
