Fruit and vegetable transport case with freezing and anti-thawing functions

Abstract

The invention discloses a fruit and vegetable transport case with freezing and anti-thawing functions, and relates to the technical field of fruit and vegetable transport equipment. The transport case comprises a main body, an upper cover, a liquid storage cylinder, mercury, a piston, a pushing rod, a movable block, an extrusion lantern ring, a closing plate, a pushing block, a conveying pipeline, a cooling cavity, a refrigeration cavity, a placement box, a knob, a circulating cavity, a fourth transmission shaft, a condensation plate, a liquid collection cavity, a pressure spring, a transfer pipeline, a first spring and a drainage pipeline. The effect of prolong refrigeration time is achieved by arranging the extrusion lantern ring, the closing plate and the movable block, the situation that fruits and vegetables are damaged when being thawed due to freezing failure is avoided, the refrigeration temperature can be adjusted, and the use effect of the device is good; and the effect of improving the refrigeration effect is achieved by arranging the condensation plate, the transfer pipeline and a second closing block, gas circulation can be formed, the situation that the refrigeration temperature is not uniform is avoided, moisture can be collected and removed, and the situation that fruits and vegetables on the bottom layer are damaged under the effect of the moisture is avoided.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable transportation equipment, in particular to a transportation box for fruits and vegetables with freezing and anti-chemical functions. Background technique [0002] At present, due to the imperfection of cold chain equipment, the loss rate in the process of fruit and vegetable logistics is as high as 25% to 30%, which is 4 to 6 times that of developed countries. Among them, transportation is the most serious link in the cold chain logistics system. At present, the commonly used device in the fresh-keeping and transportation process of fruits and vegetables is equipped with reusable refrigeration devices such as ice packs, ice boxes, etc., and freezes and preserves the fruits and vegetables in the box. [0003] However, the use effect of the current transport boxes is poor. Specifically, the refrigeration devices used in most transport boxes are ice cubes. Due to the consideration of tran...

Problems solved by technology

[0003] However, the use effect of the current transport boxes is poor. Specifically, the refrigeration devices used in most transport boxes are ice cubes. Due to the consideration of transportation costs, usually only a limited amount is placed, and the cooling time is limited. There will be a problem of freezing failure during transportation, which will lead to the thawing of the transported fruits and vegetables, which will lead to their damage
