1.谷物烘干机推广中存在的问题 1999年“双夏”期间瑞安市农机总站引进推广4台台资上海产3吨容量ACF-30型谷物烘干机,在技术推广组5名专业技术人员的共同努力下,夏收当期取得了理想的阶段性成果。据使用期间的跟踪观察,机械故障问题基本不存在。目前需要解决的主要是针对经济效益的作业方式选择问题:(1)按厂方技术要求,45℃~48℃恒低温机械烘干作业方式速度太慢,难以发挥应有经济效益。(2)一次完成烘干作业方式,机械运转周期太长,雨季农忙期间抢烘干抗灾目
1. The problems in the promotion of cereal dryer During the “Double Summer” in 1999, Ruian Agricultural Machinery Terminals introduced and promoted 4 sets of 3-ton capacity ACF-30 cereal dryers in Shanghai, With the joint efforts of personnel, the summer harvest has achieved the ideal stage results. According to tracking observation during use, the basic problem of mechanical failure does not exist. At present, the problems to be solved are: (1) According to the technical requirements of the factory, mechanical drying at constant temperature of 45 ℃ ~ 48 ℃ is too slow and it is difficult to exert its economic benefits. (2) a complete drying operation, mechanical operation cycle is too long, rainy season grab dry disaster-resistant head
