Preservation method of vegetables in logistics transportation processes

Abstract

The present invention discloses a preservation method of vegetables in logistics transportation processes. The method comprises the following steps: the vegetables are harvested, the harvested vegetables are precooled, and the precooled vegetables are put into a foam box; after the foam box is sealed, a hole is formed at one side of the foam box and a hole is formed at the upper part of the foam box, gas containing oxygen and nitrogen is filled into the foam box via the hole at the one side, wherein the mass percentage of the nitrogen is 80%-100%, and the balance is the oxygen; after the gas filling, the two holes of the foam box are sealed, and then the sealed vegetables in the foam box can be directly subjected to long-distance transportation for 3-4 days; and after the vegetables reach consumer markets, the vegetables can be sold after the foam box is opened or can be placed in the foam box. The preservation method solves the problem that the preservation is difficult during the logistics transportation processes of the vegetables, and prolongs the shelf life of the vegetables in the sales.

Description

technical field [0001] The invention relates to a logistics transportation method, in particular to a fresh-keeping method in the logistics transportation process of vegetables. Background technique [0002] At present, in the process of vegetable logistics and transportation, ice cubes are added to the foam box to cool down the temperature for preservation. Although this method can prolong the preservation period of vegetables to a certain extent, there are two problems. One is that too much ice is added to occupy the volume of the foam box, resulting in a reduction in the carrying capacity; the other is that during the transportation process, the ice partially melts into water, and the water is easily immersed in the vegetables, causing local softening and rot of the vegetables, which is even more difficult. Conducive to the preservation of vegetables. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical de...
