Problems solved by technology

However, at present, ice is commonly used as a cold storage agent in the cold chain logistics process of fresh food. The phase transition temperature of ice is 0°C, which makes it difficult to meet the temperature requirements of these fresh food. Therefore, the cold preservation effect on frozen food is limited in practical applications.

Abstract

The invention relates to a high-efficiency cold storage agent for a fresh cold chain, comprising the following components in percentage by weight: 0.1 to 3% of sodium carboxymethyl cellulose, 0.1 to 3% of anti-undercooling agent, 0.1 to 26% of energy storage agent, and the balance water. In the invention, the non-toxic, harmless and convenient inorganic salt is taken as a main component, an anti-undercooling agent is added to reduce the degree of undercooling, and also a phase separation preventing agent is added to stabilize the cold storage performance, thereby improving the cold storage efficiency and further reducing the use cost. The phase transition temperature of the obtained cold chain low-temperature cold storage agent is 0 DEG C or below, the cold storage agent has the advantagesof energy saving, safety and high efficiency, and can meet the temperature requirement of temperature-sensitive agricultural product cold chain logistics.

Description

technical field [0001] The invention relates to the technical field of logistics refrigeration, in particular to a high-efficiency cold storage agent for fresh cold chains and a preparation method thereof. Background technique [0002] Cold storage agent is a medium that uses cold storage technology to store cold energy under certain conditions. It collects and stores cold energy through phase change of materials or chemical reactions, and releases and applies cold energy when needed. The substance made by this technology that can absorb and release a large amount of cold energy and keep the system stable within a temperature range is a cold chain cool storage agent. [0003] Cold chain logistics is the key to ensuring the quality of fresh food in the circulation process. Logistics transportation under the guarantee of cold chain can effectively reduce the rot and deterioration of fresh food. Refrigerated trucks are the first choice for long-distance and large-scale fresh f...
