砖筒仓充二氧化碳安全储麦技术研究

摘要

Carbon dioxide was introduced into the wheat bulk stored in a brick silo through a duct system and was recirculated for even distribution till CO2 concentration to 70 96 in wheat bulk. After 14 - day, CO2 concentration kept above 35 %. No insects and mould in stored wheat were found by using the technique.%二氧化碳被导入一管道系统并使其在砖筒仓的粮堆内逐渐均匀分布，直到其在粮堆中的浓度达70％以上。试验期间通过该管道系统进行二氧化碳环流，经过14天停止操作，仓内粮堆中二氧化碳气体浓度保持35％以上。该气控方法储存小麦可达保鲜、无虫霉损害，安全储粮目的。
