Problems solved by technology

The required nitrogen is usually provided by the ship or by using a nitrogen cylinder. When the nitrogen source is provided by the ship, the device must complete the gas distribution operation near the gas source interface, and the fruits and vegetables need to be transferred from the gas distribution operation position to the storage. The process increases manpower and time investment, and the handling process is easy to cause mechanical damage to fruits and vegetables, resulting in poor preservation effect of fruits and vegetables; in addition, the gas source provided by the nitrogen cylinder is easily limited by the amount of nitrogen in the cylinder, resulting in the gas distribution volume often not reaching requirements, the preservation effect is unsatisfactory

Abstract

The invention relates to a design method and device of an air-conditioning fresh-keeping packaging auxiliary device. The method comprises the steps that an air compressor is connected with the filtering device, the outlet end of the filtering device is connected with the nitrogen making membrane set and the air storage equipment, and the air outlet end of the nitrogen making membrane set is connected to the nitrogen storage equipment and the gas detection assembly; the nitrogen storage equipment and the air storage equipment are respectively connected with the gas distribution equipment through pipelines; the gas distribution equipment is connected with the sealable storage device and the gas detection assembly through pipelines; the modified atmosphere packaging auxiliary device can be designed by the aid of the modified atmosphere packaging auxiliary device. The modified atmosphere fresh-keeping device can conveniently realize modified atmosphere fresh-keeping.

Description

technical field [0001] The invention relates to the technical field of modified atmosphere fresh-keeping, in particular to a design method and device of a modified atmosphere fresh-keeping packaging auxiliary device with a built-in nitrogen-generating function. Background technique [0002] Due to the long voyage time and the large number of ship crews, long-distance ships usually need to load a large amount of fruits and vegetables, grain, meat and other food. Among them, due to their own characteristics, fruits and vegetables are prone to loss of water loss, aging, rot and other deterioration phenomena during storage. Therefore, it is particularly important to keep fruits and vegetables fresh during ship operations. [0003] At present, MAP (Modified Atmosphere Packaging) modified atmosphere preservation technology is used to configure an appropriate proportion of nitrogen for preservation of fruits and vegetables to prolong the preservation period of fruits and vegetables...
