What Is A Small Vacuum Packaging Machine?

Semi Automatic Tray Sealing Machine is mainly to extend the shelf life of the product and prevent the product from oxidizing. It is generally used in food, electronic products, circuit boards, etc., and is widely used. So what is a small vacuum packaging machine?

What is a small vacuum packaging machine?

1. The vacuum packaging machine can automatically extract the air in the packaging bag and complete the sealing process after reaching a predetermined vacuum degree. It can also be filled with nitrogen or other mixed gases, and then the sealing process is completed. Vacuum packaging machines are often used in the food industry, because after vacuum packaging, the food can be resistant to oxidation, thereby achieving the purpose of long-term preservation.

2. Vacuum packaging machines include food vacuum packaging machines, which are composed of vacuum systems, vacuum sealing systems, hot pressing sealing systems, electrical control systems, etc. The external vacuum packaging machine automatically seals the packaging bag immediately after vacuuming it to a low vacuum. Due to the high vacuum degree in the bag and the small amount of residual air, the reproduction of microorganisms such as bacteria is controlled, thereby avoiding the oxidation, mildew and corruption of the items. At the same time, for some soft items, after being packaged by an automatic vacuum packaging machine, the packaging volume can be reduced for easy transportation and storage. The principle of the desktop vacuum packaging machine is to use plastic composite film or plastic aluminum foil composite film as packaging material, for solid, liquid, powdered, paste food, grains, fruits, pickles, preserved fruits, chemicals, electronic components, instruments, rare metals, etc. Is it vacuum packed or vacuum inflated.

How to maintain a small vacuum packaging machine?

1. The person using the equipment needs to check the oil level once a week and observe the color of the oil. If the oil level is below the "MIN" mark, you need to add oil. At that time, the main requirement was to be above the "MAX" mark. If there was too much, some of the excess oil would be drained. If too much condensate dilutes the oil in the vacuum pump, it needs to be completely replaced. If necessary, replace the ballast valve.

2. Under normal circumstances, the oil in the vacuum pump should be bright and clear, without any bubbling or turbidity. After the oil is left to settle, there is a milky white substance that cannot disappear, indicating that foreign matter in the oil has entered the vacuum pump oil, and new oil needs to be replaced in time.

3. The operator needs to check the air intake filter and exhaust filter once a month.

4. After the equipment has been used for half a year, it is necessary to clean the dust and dirt in the vacuum pump cavity, clean the engine cover, fan wheel, ventilation grille, and fan heat sink. Note: Use compressed air for cleaning.

5. When using a vacuum sealer, it is necessary to replace the exhaust filter once a year, clean or replace the recent filter, and use compressed air for cleaning.

6. The vacuum pump oil and oil filter need to be replaced every 500-2000 hours.
