双膜冷气囊膜下环流熏蒸应用研究

RECIRCULATION FUMIGATION WITH COOL-AIR BAG UNDER DOUBLE FILM

将粮面采用双层薄膜密闭,并使之架空,匹配2台壁挂式空调机,于夏天和秋初将冷气引入架空的气囊内,使粮面覆盖一层严实的冷气囊(即粮面动态隔热结构),不仅确保了储粮安全,而且提高了粮堆气密性,采用双膜冷气囊膜下环流熏蒸用药量少,有效浓度维持时间长,熏蒸效果好。

The test was carried out in large warehouse equipped with 2 air conditioners hanging on the wall. The surface of grain bulk was sealed with double film . The double film looks like an air bag. Cool-air was filled in the air bag in summer and autumn, thus grain bulk was covered the cool air, it can ensure grain safety, and raise airtightness of grain bulk. Recirculation fumigation with cool-air bag under double film has the advantages of using few chemical dosage, keeping effective concentration for long time, geting well fumigation effect.
