真空熏蒸即在密闭的钢铁制作的熏蒸室内放入货物,抽出绝大部分空气,再施入小量的熏蒸剂。常用的熏蒸剂为溴甲烷或环氧乙烷。环氧乙烷主要用于皮张灭菌(也可兼治害虫)。真空熏蒸较常压熏蒸更有利于毒气在货物内渗透,因此,其熏蒸时间较常压熏蒸处理害虫方面缩短12倍,处理害虫常压熏蒸需要12到24小时,真空熏蒸只要1到2 Vacuum fumigation that is sealed in a steel fumigation room into the goods, out of the vast majority of air, and then applied a small amount of fumigant. Commonly used fumigant is methyl bromide or ethylene oxide. Ethylene oxide is mainly used for skin sterilization (also pests). Vacuum fumigation is more conducive to gas fumigation infiltration in the cargo, so fumigation time is 12 times shorter than fumigation pests, 12 to 24 hours for pest fumigation, 1 to 2 for vacuum fumigation
