Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging technology, specifically to a vacuum packaging device for food grains. Background Technology

[0002] Vacuum packaging, also known as depressurized packaging, involves removing all the air from the packaging container and sealing it to maintain a high depressurization state inside the bag. The scarcity of air is equivalent to a low-oxygen effect, which eliminates the conditions for microorganisms to survive, thereby ensuring the freshness of food and preventing spoilage.

[0003] Currently, existing food and grain vacuum packaging equipment typically vacuum-packs the inside of the packaging bag. However, because most existing technologies vacuum-pack bags flat, bags containing grain cannot be filled with a large amount of grain when laid flat, resulting in waste. When too much grain is filled, some grain leaks out, creating a problem of not being able to vacuum-pack bags with large amounts of grain. Furthermore, the equipment requires evacuating air from the inside of the bag, a lengthy process that leads to a longer packaging cycle when vacuum-packing multiple bags, resulting in a longer vacuum-packing cycle for grain-filled bags.
