Overview of Vacuum Packaging Machine
Vacuum packaging machine can automatically draw out the air inside the bag to achieve a predetermined vacuum degree and then complete the sealing process. It can also be filled with nitrogen or other mixed gases to complete the sealing process. Vacuum packaging machine is often used in the food industry, because after vacuum packaging, food can be antioxidant, so as to achieve the purpose of long-term preservation.
Working Principle
Vacuum packaging machine is composed of vacuum system, pumping and sealing system, hot pressure sealing system, electrical control system and so on. External vacuum packaging machine is the bag into a low vacuum, immediately after the automatic sealing. For some soft food, by automatic vacuum packaging machine packaging, can reduce the size of the package, easy to transport and storage. The principle of tabletop vacuum packaging machine is to plastic composite film or plastic aluminum foil composite film as packaging materials, solid, liquid, powder, paste-like food, chemicals, electronic components, precision instruments, rare metals, etc. for vacuum packaging or vacuum pumping packaging.
Applications
(1) Vacuum packaging machine can be packaged according to the requirements of the goods, in accordance with the desired form, size, to get consistent specifications of the packaging, which can not be guaranteed by hand packaging. This is particularly important for export commodities, only after the vacuum packaging products, in order to achieve packaging specification, standardization, in line with the requirements of the collection of packaging.
(2) can realize the operation of hand-packing can not be achieved some packaging operations, are hand-packing can not be achieved, can only be realized with vacuum packaging.
(3) can reduce labor intensity, improve labor conditions manual packaging labor intensity is very large, such as hand-packed large volume, heavy weight products, both physically demanding, but also unsafe; and for small light products, due to the high frequency, monotonous movements, easy to make workers get occupational diseases.
(4) conducive to the labor protection of workers for some serious impact on health products, such as dusty, toxic products, irritating, radioactive products, hand-packed inevitable health hazards, while the mechanical packaging can be avoided, and can effectively protect the environment from contamination
(5) can reduce packaging costs, saving storage and transportation costs of loose products, such as cotton, tobacco, silk, hemp, etc., the use of compression packaging machine compression packing, can greatly reduce the volume, thereby reducing packaging costs. At the same time as the volume is greatly reduced, saving storage space, reduce storage costs, conducive to transportation.
(6) can reliably ensure product hygiene, such as food, medicine packaging, according to the health law is not allowed to use hand-packing, because it will contaminate the product, and vacuum packaging to avoid direct contact with the hands of food, medicine, to ensure the quality of health.
Classification Single Chamber/Double Chamber
This equipment type only need to press the vacuum cover that is automatically according to the program to complete the process of vacuuming, sealing cooling, exhaust. After packaging the product to prevent oxidation, mold, moisture, insects can preserve quality, freshness and extend the storage period of food.
According to the scope of use can be divided into:
1, food vacuum packaging machine. Such vacuum packaging machine in the vacuum packaging before the temperature should be controlled, the equipment comes with a cooling system, so there are high requirements for freshness.
2, pharmaceutical vacuum packaging machine. This kind of vacuum packaging machine should have the form of vacuum that can make the product preserved for a long time; because the pharmaceutical vacuum packaging machine should be used in the dust-free and sterile workshop and other demanding places, so this kind of vacuum packaging machine can also be applied in the sterile requirements of food packaging to achieve good results.
3, electronic products vacuum packaging machine. Electronic products using vacuum packaging machine can play on the internal metal processing parts of moisture, oxidation discoloration effect.
4, tea vacuum packaging machine. This is a set of weighing, packaging, packaging in one machine. The birth of the tea vacuum packaging machine marks the domestic level of tea packaging to enhance a big step, the real realization of tea packaging standardization.
Maintenance
1, the use of equipment, you need to check the oil level once a week and observe the color of the oil. If the oil level is lower than the "MIN" mark, you need to refuel. At that time, the main need to be higher than the "MAX" mark, if more, you need to drain part of the excess oil. If the oil in the vacuum pump is diluted by too much condensate, it is necessary to replace all of it and, if necessary, replace the gas ballast valve.
2, under normal circumstances, the vacuum pump in the oil, must be bright and clear, there can not be a little bubbling or turbidity. After the oil is still, after the precipitation, there is a milky white material that can not disappear, which means that the oil foreign matter enters into the vacuum pump oil, and it needs to be replaced into new oil in time.
3、Operators need to check once a month, inlet filter, and exhaust filter.
4、Equipment in the use of half a year, to clean the vacuum pump pump chamber dust and dirt, clean the fan hood, fan wheel, ventilation grille and cooling fins. Note: It is best to use compressed air for cleaning.
5、Using vacuum sealing machine, you need to replace the exhaust filter once a year, clean or replace the recent filter, use compressed air for cleaning.
6, vacuum machine equipment every 500-2000 hours of work, you need to replace the vacuum pump oil and oil filter.
