The function of vacuum packaging

The main function of vacuum packaging is to remove oxygen and various gases from the air, which is beneficial for preventing food spoilage. Its principle is relatively simple, as food spoilage is mainly caused by the activity of microorganisms, and most microorganisms (such as mold and yeast) require oxygen for survival. Vacuum packaging uses this principle to pump out the oxygen inside the packaging bag and food cells, causing microorganisms to lose their "living environment". Experimental results have shown that when the oxygen concentration inside the packaging bag is ≤ 1%, the growth and reproduction rate of microorganisms sharply decreases. When the oxygen concentration is ≤ 0.5%, most microorganisms will be inhibited and stop reproducing. (Note: Vacuum packaging cannot inhibit the growth of anaerobic bacteria and the spoilage and discoloration of food caused by enzyme reactions. Therefore, it needs to be combined with other auxiliary methods such as refrigeration, quick freezing, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling, etc.)

Scope of use of vacuum packaging machine:

The vacuum packaging machine is suitable for vacuum packaging of various plastic composite film bags or aluminum foil composite film bags, meat products such as roast chicken, roast duck, beef and mutton, donkey meat, sausage, ham, aquatic products, Pickled vegetables products, bean products, various additives, yeast, feed, preserved fruit, grains, medicinal materials, tea leaves, rare metals, chemicals, etc

Operation method of vacuum packaging machine

1. Dual chamber vacuum, unique design:

① This dual chamber vacuum packaging machine operates in two chambers, with one side being vacuumed and the other side being placed. The conversion is fast, and at the same time, the vacuum is converted;

② This vacuum packaging machine is composed of a vacuum chamber, an electrical control system, a vacuum system, and other parts;

③ This vacuum packaging machine consists of a vacuum system consisting of an exhaust valve, an inflation valve, a deflation valve, etc. When the vacuum pump is started, it can extract air from the vacuum chamber. When the predetermined vacuum setting is reached, the vacuum pump stops running and the entire program shifts to the next heat sealing program.

2. Fast speed, efficient vacuum:

① The main components of this machine are made of stainless steel, which is clean, hygienic, easy to clean, and corrosion-resistant;

② The dual chamber vacuum packaging machine performs vacuum pumping and sealing simultaneously, with seamless operation and ultra fast speed for dual chamber exchange;

③ To adapt to different packaging materials and packaging requirements, the machine is equipped with adjustment devices such as vacuum degree, heat sealing temperature, and heat sealing time to achieve the best packaging effect;

④ The single chamber vacuum packaging machine has the advantages of advanced design, complete functions, stable and reliable performance, and uniform and stable heat sealing temperature, making it an ideal vacuum packaging machinery;

⑤ It saves manpower, has reliable quality, high vacuum packaging efficiency, and strong applicability.
