Abstract

The invention provides a low-temperature fresh-keeping device based on hydrogen, and belongs to the technical field of low-temperature fresh keeping. The low-temperature fresh-keeping device mainly comprises a shell, an openable closed cabin, a hydrogen storage (preservation) or generation device, a refrigeration device, a hydrogen concentration real-time detection device, a gas circulation device, an automatic control device, other optional device modules and the like. Aiming at different fresh-keeping objects and opening of the cabin, the device adjusts hydrogen with a certain concentrationand time generated by the hydrogen storage (preservation) or generation device in the closed cabin under a low-temperature condition through the automatic control device, and realizes uniform distribution of hydrogen in the closed cabin by utilizing the gas circulation device; and through mutual cooperation with the hydrogen concentration detection device, potential risks caused by over-high localhydrogen concentration are avoided.

Description

technical field [0001] The invention belongs to the technical field of low-temperature preservation, and in particular relates to a hydrogen-based low-temperature preservation device Background technique [0002] With the continuous improvement of the quality of life, consumers have higher and higher requirements for freshness of ingredients and food, especially for the color, taste and nutritional content of ingredients and food. Because food raw materials, processed food or semi-finished products are easy to rot and deteriorate during storage, transportation, distribution, retail, and consumption, the sales and nutritional value of food are reduced. Therefore, in each link, it is necessary to be in the low temperature environment generated by the specific equipment required for food, so as to reduce loss, prevent pollution and deterioration, and ensure product food safety and biological safety. [0003] Low-temperature fresh-keeping devices often used in industry are gene...
