低温(或准低温)贮藏是目前一种比较好的粮食贮藏保鲜技术,最近几年以来在我国发展较快。如何利用现有房式仓进行适当的改造,使之适合低温或准低温贮粮的要求,直接关系到低温贮藏的技术经济效果。为此,我们在1975～78年利用现有房式仓机械制冷低温 Cryogenic (or quasi-low temperature) storage is a relatively good food storage and preservation technology, which has been developing rapidly in our country in recent years. How to use the existing housing warehouse for proper reformation and make it suitable for low temperature or low temperature storage of grain is directly related to the technical and economic effects of low temperature storage. To this end, we use the existing housing warehouse machinery refrigeration temperature from 1975 to 1978
