What are the principles of small vacuum packaging machines?

The vacuum packaging machine series is suitable for vacuuming, filling, and laminating a variety of foods, including meat products, seafood, fruits and vegetables, pickles, chilled meats, pharmaceuticals, hardware components, and medical devices. So, what are the principles behind small vacuum packaging machines?

1. Vacuum packaging machines use vacuum filling. Food is placed in a bag. After the air inside the bag is evacuated to a predetermined vacuum level, nitrogen or another gas mixture is filled in to seal the bag.

2. The principle behind vacuum packaging is that food spoilage is primarily caused by microbial activity, and most microorganisms (such as mold and yeast) require oxygen to survive. Vacuum packaging utilizes this principle to extract oxygen from the bag and food cells, depriving tiny organisms of their "living environment." Experiments have shown that when the oxygen concentration in the bag is less than or equal to 1%, the growth and reproduction rate of microorganisms decreases dramatically.

3.The operator of the vacuum packaging machine simply presses the vacuum lid, and the entire process of vacuuming, sealing, printing, cooling, and venting is automatically completed.
