Abstract

The present invention discloses a hydrogen preservation process system and method; the present invention relates to the field of food engineering technology; it comprises a fresh-keeping cabinet 1, wherein a hydrogen production system 5 for preparing hydrogen is designed inside the fresh-keeping cabinet 1. The hydrogen production system 5 works based on the electrolysis principle, and its core components include a pure water tank 501, a water electrolyzer 505, a separation scrubber 502, a gas cooler 503, and a gas-water separator 504. In specific implementation, the pure water tank 501 is connected to the water inlet of the water electrolyzer 505 through a pipeline to provide the water electrolyzer with pure water for electrolysis. After being powered on, the water electrolyzer 505 decomposes water into hydrogen and oxygen. Subsequent gas cooling, impurity removal, and gas-water separation steps further purify the hydrogen to ensure the purity of the output hydrogen and meet the high requirements for food preservation. Pure water is used as the electrolysis raw material, and the process is clean and pollution-free. Hydrogen is used as a fresh-keeping gas, which is non-toxic and harmless and environmentally friendly.
