摘　　要：双孢蘑菇(Agaricus bisporus)是常见的食用真菌,其质地细嫩但易变质,且鲜菇不耐贮藏。通过实验研究及回归分析,确定了双孢蘑菇切片最佳冷冻干燥工艺;在此基础上采用数值模拟的方法进行了冷阱室内温度场的分析,通过优化设计,改善了冷阱室内的气流组织。结论可为食用真菌的真空冷冻加工工艺参数控制及冻干机改造提供一定理论依据。Agaricus bisporus is a common edible fungus due to its delicate texture, but it is easy to deteriorate and the fresh body is difficult to storage.The best freeze-drying process of fungi slice was determined by experiment and regression.The flow field and temperature filed in the chilling chamber were analyzed applying the numerical simulation method based on former freeze- drying process. The positive effect on improving the air-flow organization of the chilling chamber was achieved.The theoretical basis on the conclusion for controlling freeze- drying process parameters of edible fungus and transforming the vacuum freeze-drying machine was provided.
