Description

Technical Field

[0001] This utility model relates to the field of quick-freezing and preservation technology, specifically to an immersion-type ultra-low temperature quick-freezing device with a recyclable safe liquid cooling fluid. Background Technology

[0002] Freezing technology is a common method of food storage. It extends the shelf life of food and preserves its nutritional value and texture by placing it in a low-temperature environment. Traditional freezing methods typically use slow freezing, but the ice crystals formed during this process can puncture the cell membranes of food, reducing its water-holding capacity. As freezing time increases, cell damage and protein denaturation occur, leading to increased juice loss upon thawing and a decline in flavor and texture, significantly reducing the quality of frozen products. To improve the quality of frozen food and maintain its freshness, liquid nitrogen rapid freezing technology is currently commonly used. However, this rapid freezing technology has drawbacks such as the refrigerant not being recyclable, high cost, and lack of environmental friendliness. Therefore, there is an urgent need for a low-cost, freshness-locking rapid freezing device to solve these problems. Utility Model Content
