Description

Technical Field

[0001] The utility model relates to the field of quick-frozen food processing equipment, in particular to a quick-frozen food vacuum packaging flattening device. Background Art

[0002] Quick-frozen food vacuum packaging is a method of packaging quick-frozen food in a vacuum environment. Quick-frozen food refers to food that has been quickly frozen. Low-temperature freezing can effectively maintain the quality and nutrition of the food and extend its shelf life. Vacuum packaging is to extract the air inside the packaging bag during the packaging process to create a low-oxygen environment to slow down the oxidation and corruption of the food. In the vacuum packaging of quick-frozen food, special vacuum bags or vacuum packaging films are usually used to package the food. After filling the quick-frozen food, the packaging bag is placed in a vacuum packaging machine. The vacuum packaging machine will extract the air in the bag, create a low-pressure, low-oxygen environment, and then seal the bag to prevent air from entering again. When vacuum packaging quick-frozen food, the packaging bag needs to be flattened to expel the air in the packaging bag, so that the packaging bag can remain tightly sealed. When the flattening operation is performed manually, insufficient flattening force will cause incomplete exhaust of the air in the packaging bag, thus affecting the vacuum packaging effect in the later stage.
