| 摘 要： | 在集成预冷、杀菌、气调包装三功能基础上,对当前气调保鲜包装机一般为补偿式气调而置换率较低,基于压力配气方式而气体混合精度差,半自动化而生产效率低,冷却不到位并存在二次污染等问题进行了改进,设计了一种集预冷、杀菌、气调包装一体化的全自动设备。此外,就不同包装盒及不同产品所需冷量的不同,设计了2种预冷系统模式:将半导体制冷技术应用于预冷预置气体,适用于小型冷量的包装产品,并可相应地提高其配气精度;采用制冷压缩机真空预冷系统,适用于需较大冷量的包装产品。同时对制冷模式的选择及所需冷量进行了简单的理论计算和分析。

| Abstract: | Current MAP equipment has the deficiencies of low replacement rate caused by compensation style, low gas mixing precision caused by pressure regulation, low efficiency caused by half automation, not enough cooling and sterilization, and secondary pollution. Fully automatic MAP equipment with the functions of pre-cooling, sterilization, and modified atmosphere was designed to solve the above deficiencies. Besides, two pre-cooling system modes were designed for different packaging boxes and products requirements, which were semiconductor refrigeration technology applicable to small cold quantity packaging products and refrigeration compressor vacuum pre-cooling system applied in larger cold quantity. Refrigeration mode selection and theoretical calculation and analysis methods were also introduced. |
