Vacuum Sealer

A vacuum sealer is a handy kitchen appliance that removes air from bags or containers to preserve food and other items, enhance cooking techniques, and protect various items from environmental damage. Vacuum sealing removes air, which reduces oxidation and slows down the growth of bacteria and mold, extending the shelf life of foods. Lock fruits, vegetables, meats, and dairy products in freshness, can retain their freshness and nutritional value for a longer period. It can help infuse flavors into meats, fish, and vegetables more effectively during the sous vide process.

The working principle of household food vacuum sealer mainly includes the following steps:

1. Bagging: Place the food to be encapsulated in a special vacuum bag. Vacuum bags are usually made of plastic and aluminum foil composite materials, with good air tightness.

2. Pumping: Put the vacuum bag into the sealing slot of the sealer and start the sealer. The air extractor inside the sealer starts to work, removing the air from the bag. The removal of air can slow down the oxidation process of food and extend the shelf life of food.

3. Heating seal: After most of the air is removed, the machine activates the heating element and closes the bag. The heating element will heat close the edges of the bag, thus ensuring that the bag is completely sealed. This process usually takes anywhere from a few seconds to tens of seconds, depending on the sealer and the sealer of the bag.

4. Cooling and removal: After heating the seal, the sealer will cool the seal to ensure the robustness of the seal. When finished, the packaged food can be removed.

This way can prevent food from moisture, oxidation, bacterial growth, thereby extending the storage time of food.
