Description
Technical Field
The invention belongs to the technical field of low-temperature preservation, and particularly relates to a low-temperature preservation device based on hydrogen
Background
With the continuous improvement of life quality, the consumer demand for food materials, foods and the like for preservation is higher and higher, and particularly, the demand for the color, taste and nutritional ingredients of the food materials and the foods is continuously improved. The raw materials, processed foods or semi-finished products of the foods are easy to rot and deteriorate in the processes of storage, transportation, distribution, retail sale and eating, so that the sale and edible nutritional values of the foods are reduced. Therefore, the food is required to be in a low-temperature environment generated by special equipment required by food in each link, so that the loss is reduced, the pollution and the deterioration are prevented, and the food safety and the biological safety of the product are ensured.
The low-temperature fresh-keeping device commonly used in industry is generally called a cold chain, such as a low-temperature refrigerator, a shade store, a low-temperature refrigerator, a refrigerator car, a freezer and a refrigerated container, and is used for reducing the loss of food raw materials, semi-finished products and finished products in the storage, transportation and sale links. At the consumer level, a common freezer or refrigerator is mainly used for preserving fruits and vegetables, meat and eggs, dairy products, aquatic products and the like. The effectiveness of these methods also depends on such factors as time, temperature and product shelf-life.
The hydrogen is a diatomic gas molecule, is colorless and transparent, odorless and tasteless, and has great industrial and energy values. Recent researches show that the phenomenon of reduction of endogenous hydrogen is generated during the preservation of fruits and vegetables, and the storage period of fruits and vegetables can be prolonged by adding hydrogen or hydrogen-rich water, and the patent CN 107372779A provides a method for mixing hydrogen with carbon monoxide, carbon dioxide and oxygen so as to preserve fresh meat, and provides a configuration device of the preservation gas; patent CN 107373279 a provides a method for keeping rhizoma Gastrodiae fresh by mixing hydrogen with carbon dioxide, water vapor and oxygen, and provides a device for preparing the fresh keeping gas. However, it does not combine a single preservative gas containing hydrogen with low temperatures to prolong the freshness of fresh meat and gastrodia elata; because the mixed gas is adopted, the method is complex and the cost is high. Although patent CN 111406789 a has proposed a method of mixing hydrogen with carbon dioxide and the like as a fresh-keeping gas, and combining low temperature for keeping eggs fresh. However, at present, a broad-spectrum device which can prolong the storage period of fruits and vegetables, meat products, rice and other grains, dairy products, aquatic products and the like by only utilizing hydrogen and low temperature is not available. The method is mainly characterized in that hydrogen has low density, easy escape, flammability and explosiveness, and the like, and meanwhile, the fresh-keeping effect of the hydrogen on fruits, vegetables, meat, eggs, rice and other grains, dairy products, aquatic products and the like depends on different hydrogen concentration ranges and treatment time, and the hydrogen does not completely have the dependence on concentration and time. Therefore, the low-temperature preservation device based on hydrogen gas modified atmosphere is designed, and aiming at a specific preservation object, the concentration and the processing time of hydrogen gas are automatically controlled through the automatic control device, so that the reduction of the hydrogen gas content of the preservation object in the storage period is delayed, the metabolism is inhibited, the respiratory strength and the expression of relevant aging genes and the proliferation speed of microorganisms are reduced, the low-temperature preservation device is further used for prolonging the storage period of raw materials, semi-finished products, finished products and the like such as fruits, vegetables, meat, eggs, rice and the like, milk products, aquatic products and the like, simultaneously reducing the transportation loss, and controlling the hydrogen gas concentration in an openable closed cabin below an explosion limit (4%).
