吸附法脱除果蔬气调保鲜库气氛中的乙烯

Removing The Ethylene in The Atmospheres of The Controlled Atmosphere Storage for Fruits And Vegetables

目前气调库保鲜是果蔬保鲜方法中最先进的保鲜方法之一。气调保鲜库运行的重要环节是控制气调库内气体组成和含量。本课题研究的是用变压吸附法调节控制气调库中的气体组成和含量。通过对本课题的研究提供了吸附脱除C2 H4的最佳吸附剂和工艺流程 ,使气调库保鲜气体中的C2 H4降至≤ 10ppm ,再将净化气返回气调库循环使用 ,这样可以降低果蔬保鲜的成本 。

At present,the performance of pressure swing adsorption is researched for controlling the composition and content in the controlled atmosphere storage . We find the best adsorbent and processing that remove the ethylene and make the content of ethylene not exceeding 10×10^(-6), the last purified gas return the controlled atmosphere storage.
