| 摘 要： | 气调库中最关键的设备是氧气脱除机。在引进、消化、吸收国外最先进科学技术的基础上，成功研制了闭路循环式果蔬保鲜氧气脱除机。该机采用闭路循环式的工作方式，主要由机架、氧气测量仪、分子分离罐、引风机、真空泵、过滤器以及换向阀等组成。该机的研制成功使气调库既能降低氧气浓度，又能去除储藏果蔬产生的CO2。这种低氧、适当CO2浓度的环境能有效地抑制果蔬的呼吸作用，减少果蔬储藏中营养物质的损耗，同时抑制病原菌的滋生繁殖，控制某些生理病害的发生。设备价格便宜，自动化程度高，能耗低，其主要性能指标已达到或超过国外同类产品水平，现已在国内很多气调库中得到应用。

| Abstract: | Key instrument was O2 absorber in the controlled atmosphere store.Closed circuit fruits and vegetables preservation O2 elimination device was designed successfully based on introduction，digestion and absorption of foreign advanced technology.With closed circuit working mode，machine was composed of frame，oxygen measuring instrument，molecular separation tank，induced draft fan，vacuum pump，filter and reversing valve，etc.This machine could decrease oxygen concentration and remove carbondioxide in storage of fruits and vegetables.Environments of low oxygen concentration and suitable carbondioxide concentration were beneficial to inhibit the respiration of fruits and vegetables，and that could reduce the loss of nutrients.Meanwhile，that could inhibit the propagation of pathogen and prevent the occurrence of physiological diseases.Machine had the advantages of cheap price，high automation and low energy consumption，its main performance index had reached or exceeded the international advanced level，now it had be used in lots of controlled atmosphere store in China. |
