Gas freshness preservation transportation box for fresh food delivery

Abstract

The invention discloses a gas freshness preservation transportation box for fresh food delivery. The transportation box comprises a box body and a sealed storage space, a heat insulation interlayer isarranged on the inner side of the box body, the sealed storage space is arranged on the inner side of the heat insulation interlayer, the top of the sealed storage space is provided with a top heat conduction plate, the upper side and the lower side of the top heat conduction plate are provided with heat conduction fins, and one side of the sealed storage space is provided with a taking and placing opening. Fresh food is stored by the sealed storage space, a top refrigerating bin can store dry ice so as to cool the fresh food, the top refrigerating bin is spaced from the sealed storage spacethrough the top heat conduction plate, therefore, the temperature of sealed storage space can be reduced, and the freshness preservation time of the fresh food can be prolonged; and meanwhile, the toprefrigerating bin communicates with the sealed storage space through a connecting pipe, carbon dioxide gas produced by the dry ice can enter the sealed storage space through the connecting pipe, therefore, the carbon dioxide content in the sealed storage space is improved, oxidation of vegetables and fruits is restrained, and the freshness preservation effect of the fresh food is further improved.

Description

technical field [0001] The invention relates to the field of fresh food distribution equipment, in particular to a gas fresh-keeping transport box for fresh food distribution. Background technique [0002] With the continuous development of the logistics industry and online shopping, people are no longer limited to buying ordinary goods on the Internet. Some daily necessities and even fresh food are purchased online. Therefore, many online platforms for fresh food sales have emerged. After purchase, the courier usually transports them home. However, fresh products are different from ordinary products in that they have a short shelf life and are fragile. In order to ensure the freshness of fresh products, on the one hand, it is necessary to speed up the delivery. Keep it fresh. The applicant found that the current transport boxes for fresh food delivery are generally just ordinary incubators, and goods and ice cubes are placed inside, so that the temperature can be kept cons...

AI Technical Summary

Problems solved by technology

The applicant found that the current transport boxes for fresh food delivery are generally just ordinary incubators, and goods and ice cubes are placed inside, so that the temperature can be kept constant in a short time, thereby prolonging the fresh-keeping time, but the metabolism of plant cells is mainly oxidation. And reduction reaction, in which the utilization rate of oxygen determines the speed of metabolism, thus affecting the quality of fresh storage, so it is difficult to keep fresh for a longer period of time only by maintaining a low temperature environment, and a variety of fresh-keeping methods must be used
