Cold-chain freshness-preservation storage and transportation packaging box for fruit

Abstract

The invention belongs to the field of cold-chain packaging boxes, in particular to a cold-chain freshness-preservation storage and transportation packaging box for fruit. According to the solution provided by the invention, the cold-chain freshness-preservation storage and transportation packaging box comprises a hollow base, a storage container and a top cover, wherein the rectangular storage container is mounted at the top end of the base; the middle of the storage container is provided with a heat conduction cylinder of which the bottom end is fixedly connected to the top end of the base; aplurality of partition plates are connected between the heat conduction cylinder and the inner wall of the storage container; a plurality of stacked storage mechanisms are arranged between every twoadjacent partition plates; the top end of the storage container is in threaded connection with the top cover; and a storage battery, an electric motor and a liquid nitrogen tank are adjacently mountedinside the base. The cold-chain freshness-preservation storage and transportation packaging box can continuously lead liquid nitrogen out into heat conduction liquid in the heat conduction cylinder during transportation, and performs cold storage and freshness preservation of the fruit in the storage container through the heat conduction liquid, thereby prolonging the shelf life of the fruit. Inaddition, through the arrangement of the storage mechanisms, the cold-chain freshness-preservation storage and transportation packaging box can play the buffer and shock absorption role on the transported fruit during transportation, so that the fruit is prevented from being shaken resulting in hard collision and damage.

Description

technical field [0001] The invention relates to the technical field of cold-chain packaging boxes, in particular to a fruit cold-chain fresh-keeping storage and transportation packaging box. Background technique [0002] Fruits are loved by people because of their delicious taste and delicious taste. Fruits often need to be transported over long distances during the actual sales process. Therefore, it is very necessary to keep fruits fresh. The current fruit packaging boxes usually only have the function of storage. , the fruit cannot be well preserved, and the fruit may deteriorate or rot easily during the transportation process, and it is impossible to transport the fruit by cold chain transport vehicles during the short-distance transportation. Therefore, we propose a Fruit cold chain fresh-keeping storage and transportation packaging box.
