Packaging Machine
From the 1950s to the mid-1980s was the development period, starting from the production of simple vacuum pumps. At that time, there were fewer than 20 enterprises producing vacuum equipment nationwide, mainly producing mid-to-low grade vacuum acquisition equipment, such as mirror coating machines and cigarette packaging machines. From the late 1980s to the entire 1990s was the period of development for China's vacuum industry. During this time, the number of manufacturing enterprises increased to nearly 3,000, with 35,000 employees. After the technical renovations during the "Seventh Five-Year Plan" and "Eighth Five-Year Plan," the overall level of the vacuum industry improved significantly. In terms of processing conditions, advanced production equipment such as machining centers, CNC machine tools, and resin sand castings began to be equipped in enterprises. By 1996, driven by the magnesium smelting industry, the vacuum industry experienced rapid development.
A packaging machine is equipment that places the packaging material outside the vacuum chamber to complete vacuum packaging. The external vacuum packaging machine is mainly designed for vacuum packaging of larger packaged items. Unlike the internal vacuum packaging machine, the external vacuum packaging machine uses a vacuum nozzle inserted into the packaging bag of the item to be packaged to evacuate the air, then withdraws the nozzle, and completes the sealing.
The entire packaging machine is made of 304-grade stainless steel material specialized for equipment, and the control part uses a PIC computer control system. The vertical cabinet vacuum packaging machine is mainly used for vacuum packaging of powders, fine particles, liquids, or large packaged items. It has a large vacuum chamber volume and a vertical sealing method for the bag mouth. It can place the product's outer packaging (such as barrels or boxes) directly into the vacuum chamber to complete the vacuum sealing of the inner bag. The door-opening operation method facilitates the placement of heavy objects. This model can be customized according to special size and configuration requirements. It is widely used in industries such as feed, chemical, food, and electronics. 
Snack foods such as chicken feet, duck feet, duck neck, dried tofu, small fish, fish pieces, and various cooked foods can only enter the market through vacuum packaging and high-temperature sterilization. The vacuum packaging of these products is done manually, with vacuum chambers evacuating the air. Each operation process is intermittent, which easily causes product contamination or cross-infection between people and items during the processes, resulting in low efficiency, high labor intensity, and high overall costs. The widespread shortage of human resources limits the development of the industry and leads to slow growth of the snack food industry.
