Deep sea fresh food is rich in nutritional ingredients such as proteins, unsaturated fatty acids, minerals and the like which are vital to human health, but is also more susceptible to degradation due to chemical actions such as microbial contamination, oxidation, enzymolysis and the like due to its high nutritional value. Along with popularization of healthy diet concepts and deepening of marine resource cognition, market demands of deep sea fresh are continuously increased, and in order to meet the demands, it is particularly critical to ensure the quality of the deep sea fresh and prolong the fresh-keeping period of the deep sea fresh and apply more advanced fresh-keeping technology.

Wang et al performed freezing and carbon dioxide conditioning treatments on tilapia fillets, and found that the technique could inhibit microbial growth, alleviate moisture migration rate, and shorten freezing time. Niu et al have obvious fresh-keeping effect on turbot fish meat through the CO 2 and N 2 refrigeration air-conditioning synergistic effect, and have obvious advantages in sensory index and chemical index compared with other fresh-keeping methods. The gas adopted by the air-conditioning refrigeration fresh-keeping technology generally comprises carbon dioxide, ammonia and the like, and the gas is nonpolar molecules and does not cause biochemical reaction in cells.

The hydrogen generator 12 generates hydrogen by electrolysis of water or other chemical means. The electrolytic water hydrogen production can not produce any harmful pollutant, has higher safety, is a very clean and environment-friendly hydrogen production mode, can be started and stopped at any time, and can be expanded or contracted according to the needs, so that the hydrogen production mode is very flexible and can be adjusted according to the actual needs.
In one embodiment, the control panel 22 is connected to the refrigerated interior machine 20, the control panel 22 is connected to the hydrogen monitor 13, and the control panel 22 is connected to the ventilation system 18. The control panel 22 can observe and control the refrigeration temperature, the hydrogen flow, the hydrogen time, the gas circulation system and the like in the refrigerator, and maintain the stable state of the refrigerator 1.
The modified atmosphere fresh-keeping refrigerator 1 for deep sea fresh provided by the invention has the advantages of quick freezing, high-efficiency fresh keeping, low energy consumption, green storage and the like, effectively improves the fresh-keeping effect of deep sea fresh products which are extremely easy to be subjected to environmental influence and spoilage, reduces the overall energy consumption and operation cost of the refrigerator 1, improves the economic benefit, and provides an innovative and high-efficiency solution for the transportation and storage of the deep sea fresh products.
