Mango cold-chain logistics fresh-keeping device

Abstract

The invention discloses a mango cold-chain logistics fresh-keeping device in the technical field of mango refrigeration. The mango cold-chain logistics fresh-keeping device comprises a refrigeration chamber and a plurality of placing boxes, wherein a plurality of through holes are formed in the two sides of each placing box; each placing box is provided with a fixing groove and a fixing box; a first sealing assembly is arranged in each fixing groove; and a second sealing assembly is arranged in each fixing box. According to the mango cold-chain logistics fresh-keeping device provided by the invention, the fixing boxes on the placing boxes are in contact with the corresponding fixing grooves or second top plates, so that first top plates eject sealing cylinders open, meanwhile, the fixing boxes eject sealing plates open, inner cavities of the placing boxes communicate with the refrigerating chamber, and the temperature of the refrigerating chamber is kept through a refrigerator, so that the purpose of refrigerating is achieved; cold air in the refrigerating chamber can be in contact with mangoes in the placing boxes, so that the refrigerating effect is improved; and when the placing boxes are taken out of the refrigerating chamber, the sealing plates and the sealing cylinders return to seal the placing boxes, so that the loss of internal cold air is slowed down, and the refrigerating time is prolonged.

Description

technical field [0001] The invention relates to the technical field of mango refrigeration, in particular to a mango cold chain logistics preservation device. Background technique [0002] Mango is the common name of mango. Mango is a large evergreen tree of Anacardiaceae native to India, with leathery leaves and alternate flowers; small, polygamous, yellow or light yellow flowers in terminal panicles. The drupe is large, compressed, 5-10 cm long, 3-4.5 cm wide, yellow when ripe, sweet in taste, hard core. [0003] Mango is one of the famous tropical fruits. Mango fruit contains sugar, protein, and crude fiber. The precursor carotene of vitamin A contained in mango is particularly high, which is rare among all fruits. Secondly, the vitamin C content is not low. Minerals, proteins, fats, sugars, etc. are also its main nutrients. It can be used to make fruit juice, jam, canned food, pickles, hot and sour pickles, mango milk powder, candied fruit, etc. [0004] Cold chain l...

AI Technical Summary

Problems solved by technology

[0006] When keeping fresh in existing logistics, mangoes are usually placed in a box and placed in a refrigerator for transportation. The simplest type of box is a hollowed-out storage box. Mangoes can fully contact with the air in the refrigerator to improve refrigeration. However, during the process of taking out the storage box from the refrigerator and moving it, the mango will also quickly come into contact with the hot air outside, and some will use a closed box to prevent the mango from being bumped. There is a structure such as a box cover, so that after the box enters the refrigerator, the air temperature in the inner cavity cannot drop rapidly, which is consistent with the refrigerator
