Problems solved by technology

The common problem of the cold storage agent in the prior art is that a large amount of chemical raw materials are introduced to improve various indicators of cold storage, and it cannot be absolutely non-toxic. Once leakage occurs during use, it will damage the transported or stored food and Pollution caused by medicines, thereby causing serious consequences of poisoning of users or consumers
In order to ensure that the cooling agent does not leak, it is necessary to use high-strength and thick packaging materials for the cooling agent, which indirectly increases the use cost and supporting cost of the cooling agent

Abstract

A cool storage agent with low phase-transition temperature comprises components in percentage by mass as follows: 15%-25% of sodium chloride, 10%-15% of sodium carboxymethylcellulose, 0-5% of dietary cellulose, 0-15% of high fructose corn syrup and the balance of water. Due to the fact that the adopted preparation raw materials are food-grade, the cool storage agent with the low phase-transition temperature has the advantages of being non-toxic, harmless and pollution-free, can be widely applied to the fields of cold-chain logistics, low-temperature preservation, intelligent cooling stations, clinical care and the like, and the cool storage agent is prevented from causing secondary hazards on food or drugs in storage and transportation processes.

Description

technical field [0001] The invention relates to the technical field of cold storage, in particular to a non-toxic, harmless and pollution-free low phase transition temperature cold storage agent. Background technique [0002] Cold storage technology uses physical, chemical, mechanical and other effective means to store cold energy in the cold storage agent, and release the stored cold energy when needed. The material produced by this technology, which can store cold energy efficiently and meet various physical and chemical requirements, is called a cold storage agent. [0003] Coolant is usually a viscous jelly mixture composed of organic or (and) inorganic compounds, which can absorb and store a large amount of cold energy at low temperatures, and release a large amount of cold energy at higher temperatures, which can be stored for a longer period of time. Maintain a low temperature environment in and around a small area. [0004] The main problem in the field of cold cha...
