Gas external vacuum packaging

Types of Gas External Vacuum Packaging

Gas external vacuum packaging refers to a vacuum packing method that entails removing air from the internal parts of a package to enhance product preservation, shelf life, and security. Primarily, all gas external vacuum packagings are used as industrial-grade food sealers in commercial kitchens, but they can also be used to package non-food items such as electronics and hardware.

Gas external vacuum packaging machines come in different styles and functionalities, including gas external vacuum packaging machine (belt), gas external vacuum packaging machine (tabletop), and gas external vacuum packaging machine (horizontal barrel). Each option has its own unique characteristics that set it apart from the rest.

• Gas External Vacuum Packaging Machine (Belt): A gas external vacuum packaging machine (using a belt) commonly features an electric drive and uses a conveyor system for automatic sealing. Unlike most vacuum packaging machines, this particular external machine doesn't have a piston pump. Instead, a vacuum is created using compressed air, which gas has to use to effectively pack food products. It's worth noting that this machine is particularly well-suited for very moist food products, like ground beef, as it incorporates a special filter that prevents any liquid from entering the vacuum chamber. It effectively avoids any contamination while ensuring every last bit of air is removed from the product.
• Gas External Vacuum Packaging Machine (Tabletop): This packaging machine at a table is designed to accommodate standard-size products and is recommended for businesses with limited space requirements. The machines use a digital control unit, which makes it look and work more like a commercial vacuum sealer. Most external vacuum packaging tabletop machines have up to 12 cycles per minute, and their sealing bar length ranges between 6 to 12 inches. For smaller models, the sealing bar is usually about 6 inches. The device can pack moisture quickly, and depending on the settings, it may gas-pack a product with its moisture content. It does this by using air in the room. Many external vacuum packaging machines (tabletop models) are leak-proof and mostly have digital controls to gasspack products.
• Gas External Vacuum Packaging Machine (Horizontal Barrel): This is a heavy-duty machine with a horizontal configuration that mostly gasses food products with a short cycle time. It usually has a window on the upper side of the barrel so that one can clearly see the progress of vacuum sealing. The window usually provides an overview of the sealing Bar's precision and how the gassing time varies depending on the size of the food product. Additionally, you'll find that this machine is operated by a switch plus an electric drive, making it suitable for all kinds of industries.

Specifications and maintenance of gas external vacuum packagings

Gas external vacuum packaging machines are available in different specifications. The packaging gas external machine usually has a dimension that ranges from 22x15mm for smaller machines to 25x21mm for larger machines. The sealing bar length varies according to the size of the machine. For instance, external vacuum sealers with a 12mm to 15mm sealing bar are suitable for packaging food items such as fish and meat. In addition, external vacuum sealer packages with a sealing bar length of 30cm are suitable for commercial use. They can be used to package fruits and vegetables for export.

Gas external vacuum packaging machines are made for 110V to 240V voltage. They are available in stainless steel, steel, and aluminum alloy. The machine weighs 12 to 20 kg, depending on the construction material. The power of a gas external vacuum packaging machine ranges from 90 watts to 250 watts.

The maintenance requirement for the external gas vacuum packaging machine is easy. Regular cleaning is important to prevent product contamination. It is better to use a mild detergent and warm water on the external surface of the machine to get rid of any residue or dirt. Stubborn stains should be removed with a soft brush. It should never be immersed in water or used cleaner on the inside parts. It should be dried off well and cleaned after every use to prevent the buildup of bacteria. For gas external vacuum packaging, the sealer should be wiped with a damp cloth and dried immediately to avoid rusting of the sealing element.

For any external vacuum pack gas, the moving parts, like springs and pulleys, should be lubricated from time to time. Routine maintenance checks should always be done on external vacuum packages to identify any damages and parts that need lubrication. In case the oil or dirt build-up is too much, the external vacuum package should be disassembled and cleaned with a lint-free cloth and some alcohol.

Faults in gas suction external vacuum packaging can be easily repaired. The sealing bars can be replaced if burnt. Sealing wires that show any damages should be replaced to avoid reoccurring faults. The vacuum pump and motor drive belts should be checked from time to time. They can be changed if worn or damaged. Whenever the machine is opened for maintenance or repairs, the parts should be lubricated to prevent easy tear and wear.
