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

Embodiment 1

[0026] Embodiment 1, taking the cold storage agent of kilogram unit as an example, every kilogram of cold storage agent of the present invention contains 50 grams of sodium chloride, 50 grams of sodium carboxymethyl cellulose, 50 grams of dietary cellulose, and 0.05 grams of food coloring. Edible essence, the rest is water.

[0027] Cold storage agent of the present invention comprises the following processes during preparation:

[0028] A. Heat the water to boiling, and filter and descale the water after cooling;

[0029] B. Heat the water to boiling again, add sodium chloride, and add sodium carboxymethylcellulose and dietary cellulose while stirring to form a porridge-like mixture;

[0030] C. After the mixture is naturally cooled to room temperature, food coloring is added and stirred evenly to obtain the cooling agent.

[0031] The obtained per kilogram of cold storage agent can release cold energy in the incubator for at least 2 hours, so as to keep the temperature in ...

Abstract

The invention relates to a cold storage agent which comprises the following materials by weight part: 5-15% of sodium chloride, 5-10% of sodium carboxymethylcellulose, 2.5-5% of dietary fiber and the balance of water. The adopted preparing raw materials are all food-grade raw materials, so that the end product of the cold storage agent provided by the invention is also at food-grade and has the advantages of being non-toxic, harmless and pollution-free; the cold storage agent can be widely applied to the fields of cold-chain logistics, low temperature preservation, intelligent cold-making station, clinical medical, and the like; the secondary harm of the cold storage agent to the food or medicine in the storage and transporting processes can be avoided.

Description

technical field [0001] The invention relates to the technical field of cold storage, in particular to a food-grade, non-toxic, harmless and pollution-free 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 chain transportation suc...
