A kind of standardized cold box system and cold chain transportation method for cold chain transportation

Abstract

The invention discloses a standardized cold box system for cold-chain transportation and a cold-chain transportation method. The standardized cold box system comprises first-stage cold boxes, second-stage cold boxes and third-stage cold boxes. The external dimension of the two or four second-stage cold boxes is identical to that of one first-stage cold box after the two or four second-stage cold boxes are spliced. The dimension of the second-stage cold boxes has a diploid relation with that of the third-stage cold boxes, and the external dimension of one second-stage cold box is identical to that of a set number of third-stage cold boxes after the third-stage cold boxes are spliced. The first-stage cold boxes are used for main transport or branch transport of major clients. The second-stage cold boxes are used for branch transport or end distribution of small and medium-sized clients, or the second-stage cold boxes are used for main transport after being spliced. The third-stage cold boxes are used for end distribution of individual small clients or branch transport after being spliced. The needed cold box dimension is selected according to the quantity of cargoes to be transported and the categories of the cargoes, the different kinds of cargoes are placed into the cold boxes of different dimensions for spliced transportation, the freshness of various kinds of products can be improved, and the cargo distribution efficiency can also be improved.

Description

technical field [0001] The invention relates to a standardized cold box system and a cold chain transportation method capable of realizing one-stop cold chain delivery, realizing one-stop delivery of standardized cold boxes, and improving the efficiency of vehicle change at each logistics node. Background technique [0002] The development level of cold chain logistics is affected by many factors, among which the quality of refrigerated transportation equipment is an important restrictive factor. The existing refrigerated vehicles have the following problems: [0003] (1) The temperature of the cold box is single [0004] Different types of goods have different temperature requirements. In today's cold chain transportation and distribution links, whether it is a refrigerated truck, a special cold chain box, or an ice bag, it can only maintain a single temperature. Mixing goods that require different temperatures at one temperature will greatly reduce the freshness of fresh ...

AI Technical Summary

Problems solved by technology

Mixing goods that require different temperatures at one temperature will greatly reduce the freshness of fresh food; separately loading them in different cold boxes for transportation will reduce the efficiency of transportation and distribution, causing great damage to cold chain transportation equipment. big waste

[0005] (2) Unreasonable utilization of refrigerated truck space

[0006] In the cold chain transportation, there is basically no detailed space planning. In order to maintain the refrigerated temperature of the frozen goods, the goods are tightly stacked on the floor of the cold box, which reduces the utilization rate of the cold storage space.

At the same time, the goods are squeezed against each other and the loss is large, which cannot ensure that the goods are in good condition and increases the loss of the goods.

[0007] (3) It is difficult for large refrigerated trucks to enter the city

[0009] (4) Frequent unpacking and unpacking of transport nodes
