Description
Technical Field
[0001] The utility model relates to the technical field of food production, in particular to a food segmented liquid nitrogen quick-freezing tunnel structure. Background Art
[0002] In the food production sector, quick-freezing technology plays a vital role. It not only effectively extends the shelf life of food, but also maximizes the preservation of its original flavor and nutritional value. Especially in the fast-paced modern world, people's demand for convenient and healthy food is growing, making quick-frozen food a mainstream choice in the market. Quick-freezing technology effectively inhibits microbial activity and slows the spoilage process by rapidly lowering the temperature of food to below freezing, while ensuring that the food retains its excellent taste and texture after thawing. This technology is widely used in the production of various foods, from common meats and seafood to complex pre-prepared dishes, all of which benefit from the innovation and advancement of quick-freezing technology.
[0003] For specific high-end pre-prepared dishes, such as Buddha Jumps Over the Wall, the quick-freezing process is more sophisticated. As a classic Fujian dish that combines a variety of precious ingredients, Buddha Jumps Over the Wall requires special attention to the separation of the broth and dry matter during its quick-freezing storage. This step is crucial because it ensures that during the quick-freezing and subsequent thawing process, the dry matter (such as sea cucumber, abalone, chicken, etc.) will not be excessively squeezed and deformed due to the freezing of the broth, thereby maintaining the integrity of the shape and taste of the ingredients. This processing method can not only effectively prevent the adhesion of ingredients, but also ensure that the thawing Buddha Jumps Over the Wall broth is clear and the dry matter is fresh and juicy, perfectly restoring its original flavor and essence.
[0004] In the prior art, when freezing food, the food is usually placed in a container and then sent to a liquid nitrogen freezing tunnel for freezing. However, this liquid nitrogen freezing method is particularly inconvenient when processing foods such as Buddha Jumps Over the Wall that require solid-liquid separation and packaging. This is because the unique freezing requirement of Buddha Jumps Over the Wall is that it requires the soup to be frozen first, and then solid dry matter is added for secondary freezing. Traditional liquid nitrogen freezing tunnels cannot flexibly insert this step into the freezing process. As a result, in actual operation, the soup must first be frozen separately, then removed after it is completely solidified, and then dry matter is added on top of it, and finally it is sent back to the freezing tunnel for secondary freezing. This process is not only cumbersome and complicated, greatly increasing production time and cost, but also multiple freeze-thaw cycles may damage the quality and taste of the food, cause the loss of nutrients, and increase the risk of food contamination. It constitutes a significant disadvantage for maintaining the flavor and quality of high-end foods such as Buddha Jumps Over the Wall. Utility Model Content
