江苏省储粮通风以自然与机械相结合,机械通风通常采用4—72—11型4.5号风机,风道设置有隧道、固定地槽、存气箱三种形式,方法有塑料薄膜封面定点开管吸风,地槽整仓吸风及揭膜逐段吸风,以吸入式为主,降温效果都比较好。但怎样以最简便、最经济和易于上马的方法取得和保持粮食低温呢?昆山县西门粮库自一九八○年以来采用存气箱降温的方法,经过试验、实践、改进,已经取得较为理想的效果,目前存气箱吸风降温已在昆山县所有基层单位使用并受到广大保粮职 Jiangsu Province, grain storage ventilation with natural and mechanical combination of mechanical ventilation is usually 4-72-11 type 4.5, the wind tunnel is provided with a tunnel, a fixed slot, the air box in three forms, the method of plastic film cover fixed point open Pipe suction, slotting the entire warehouse sucking and uncovering paragraph by paragraph suction, suction-based, cooling effect is better. But how to obtain and maintain low temperatures in the simplest, most economical and easy-to-start way? The method of reducing the temperature of storage tanks in Kunshan County Ximen Grain Depot since 1980 has been tested, practiced and improved The ideal effect, the current air box suction cooling has been used in all grass-roots units in Kunshan County and by the majority of food security
