Leaf vegetable fresh-keeping storage and transportation box with self-adjusting inner environment and using method of storage and transportation box

Abstract

The invention relates to a leaf vegetable fresh-keeping storage and transportation box with a self-adjusting inner environment and a using method of the storage and transportation box. The storage andtransportation box is composed of a box body, moisture-absorbing and water-supplementing vegetable containing bags, CO2 temperature regulators, supporting partition plates, water accumulation tanks and fixing buffering pull ropes; the box body is composed of a main box body and a box cover, wherein the main box body and the box cover are fixed and sealed through sealing adhesive tapes; the moisture-absorbing and water-supplementing containing bags are composed of water-absorbing materials so that water vapor in the box body can be absorbed to supplement lost moisture of leaf vegetables; the CO2 temperature regulators are composed of ice blocks and dry ice which are placed at the bottom of the box body, the total weight of ice bags is not smaller than half of the total weight of the vegetables, and the total weight of the dry ice is 0.05%-0.1% of the total weight of the vegetables; and the supporting partition plates and the fixing buffering pull ropes are connected with the upper partof the moisture-absorbing and water-supplementing vegetable containing bags so that vegetable bodies in the vegetable containing bags can be adjusted to be in an upright state. The storage box is exquisite in design, convenient to transport and capable of effectively delaying leaf vegetable aging, the fresh state of the leaf vegetables is kept, and the shelf life is prolonged.

Description

technical field [0001] The invention relates to a storage and transportation preservation technology for agricultural products, in particular to a fresh-keeping and quality-preservation device used in the post-harvest storage and transportation of leafy vegetables and its usage methods such as harvesting time requirements, placement, storage and transportation, etc., specifically a kind of A fresh-keeping storage and transportation box for leafy vegetables with self-adjusting internal environment and a use method thereof. Background technique [0002] Leafy vegetables have the characteristics of large surface area, high water content, and crisp and tender tissues. After harvesting, they generate a large amount of respiratory heat, evaporate water quickly, and are susceptible to mechanical damage. Yellowing, debonding, and rot often occur during storage. . According to the survey, post-harvest losses due to mechanical damage and dehydration are as high as 20-30%. In the proc...
