Special heat preservation box for storage and transportation of fruits and vegetables

Abstract

The invention relates to the technical field of fruit or vegetable heat preservation boxes, in particular to a special heat preservation box for storage and transportation of fruits and vegetables. The special heat preservation box comprises a box body and a lifting cover hinged to the top of the box body. The box body is of a three-layer structure and sequentially comprises an inner container layer, a heat preservation layer and a heat insulation layer from inside to outside. When fruits or vegetables are stored and transported in the heat preservation box, pressure-proof plates which are sequentially arranged at intervals from bottom to top are further arranged in the heat preservation box and used for carrying out layered pressure-proof placement on the fruits or the vegetables. The inner container layer is a sterilization container layer made of PP or PE and a nano-silver zinc ion sterilization material in a mixed mode. And the thermal insulation layer is prepared by mixing a PP (Polypropylene) or PE (Polyethylene) homopolymerized or PP / PE copolymerized material, a PU (Polyurethane) or PP foaming material and nano particles. The special heat preservation box integrates nano technology, smart design and multiple functions, and solves three problems of fruit and vegetable storage and transportation: the fruit and vegetable storage and transportation box is convenient to stack and occupies less space; the heat preservation box can be recycled for a long time, logistics cost is low, and environment pollution is avoided; and heat preservation and freshness retaining are realized, harmful gases are eliminated, so that the fresh-keeping period of the fruits is prolonged.

Description

technical field [0001] The invention relates to the technical field of fruit or vegetable incubators, in particular to a special incubator for storage and transportation of fruits and vegetables. Background technique [0002] With the improvement of living standards and the rapid development of the catering industry, food delivery is a new profit growth point in the catering industry. Enjoying all kinds of delicacies at home and family has become a healthy and natural way of life, which is more common in foreign developed countries. It is also becoming more and more popular in the country. The incubator has attracted the attention of the catering industry with the concepts of safety and environmental protection, cold and heat preservation, and easy portability. The insulated box is a bag with thermal insulation performance used in takeaway food delivery. Insulation boxes are divided into different types according to different product textures, including plastic, foam, meta...

AI Technical Summary

Problems solved by technology

[0003] The storage and transportation of fruits and vegetables composed of EPS foam boxes and plastic turnover boxes has the following pain points: first, the EPS foam boxes are thrown away after 1-2 times, polluting the environment; It is difficult to recycle large insulated boxes, and the cost is high; Fourth, there are a large number of fruit shops, the shops are small, and there is no space for large-scale refrigerators (the small ones are not enough), and it is difficult to "overnight" the fruit
