Problems solved by technology
[0002] At present, MAP (Modified Atmosphere Packaging, modified atmosphere packaging) technology has two main disadvantages: the modified atmosphere bags used to store fruits and vegetables are easily scratched by sharp objects, making them unable to be reused
For example, when the modified atmosphere bag is damaged during the loading process or the picking process, when the fruits and vegetables in the modified atmosphere bag are not completely taken out, a new modified atmosphere bag needs to be replaced, which increases the workload and wastes manpower; secondly, it is used to detect gas parameters. Testing equipment can only provide timely data, and fresh-keeping parameters during fruit and vegetable storage cannot be traced

The invention relates to a modified atmosphere fresh-keeping system and a design method of the modified atmosphere fresh-keeping system. The method comprises the following steps: connecting a plurality of controlled atmosphere turnover boxes in series to form a controlled atmosphere turnover box group, sequentially connecting a gas making device, a filtering device and a nitrogen-oxygen separation device, and respectively connecting a gas outlet of the nitrogen-oxygen separation device with a purity adjusting device and a gas detection device, the plurality of controlled atmosphere turnover box groups are connected in parallel with the purity adjusting device, and the purity adjusting device adjusts nitrogen with different purities to be supplied to the controlled atmosphere turnover boxes for use according to different gas using requirements of each group of controlled atmosphere turnover boxes. The invention can be used for designing a modified atmosphere fresh-keeping system. The invention belongs to the field of fresh-keeping systems.
Description
technical field [0001] The invention relates to the field of fresh-keeping technology, in particular to a modified atmosphere fresh-keeping system and a design method. Background technique [0002] At present, MAP (Modified Atmosphere Packaging, modified atmosphere packaging) technology has two main disadvantages: the modified atmosphere bags used to store fruits and vegetables are easily scratched by sharp objects, making them unable to be reused. For example, when the modified atmosphere bag is damaged during the loading process or the picking process, when the fruits and vegetables in the modified atmosphere bag are not completely taken out, a new modified atmosphere bag needs to be replaced, which increases the workload and wastes manpower; secondly, it is used to detect gas parameters. The testing equipment can only provide timely data, and the preservation parameters during the storage of fruits and vegetables cannot be traced. Contents of the invention [0003] Aim...
