Working Principle Of Food Vacuum Packaging Machine

Modified Atmosphere Packaging Equipment: With the increase of packaging product characteristics, the packaging methods of food vacuum packaging machines are also getting higher and higher. The food vacuum packaging machine uses plastic or plastic aluminum foil film as packaging material, automatically extracts the air in the packaging bag, and completes the sealing process after reaching a predetermined vacuum degree. Alternatively, nitrogen or other mixed gases can be filled, and then the sealing process is completed. So today, the editor will take you to find out!

Food vacuum packaging machines are often used to package products that are easily oxidized, moldy or deteriorated by moisture, because after vacuum packaging, the products can resist oxidation, thereby extending the service life of the products.

Food vacuum packaging machines are divided into internal and external vacuum, as well as what we often call fully automatic vacuum packaging machines. Among these three series, there are several major categories such as internal suction, single chamber, double chamber, cabinet type and continuous rolling type.

Vacuum: When the vacuum chamber is closed, the vacuum pump works, the vacuum chamber starts to evacuate, and the bag is evacuated at the same time.

Heat sealing: When the IDT breaks, the outside atmosphere enters the heat sealing chamber through the air inlet on the upper part of the IDT. The heat sealing chamber is inflated by the pressure difference between the vacuum chamber and the heat sealing chamber, so that the upper heat pressing frame moves down to press the bag mouth; at the same time, the heat sealing transformer works and starts to seal; at the same time, the time relay 2SJ works, and the heat sealing is completed after a few seconds.

The selection of food vacuum packaging machines, starting from the product, is a contemporary product with good production advantages. A good vacuum packaging machine can not only strengthen the details of the entire vacuum packaging, but also cope with the packaging environment and position the product. According to the current selection criteria, if we really understand the selection of food vacuum packaging machines, its advantages and market logic will have a more straightforward effect. In the process of qualitative analysis, there is also greater room for the verification of the practicality and value of food vacuum packaging machines.

Application areas of food vacuum packaging machines.

Paper plastic, plastic plastic, plastic steel, PE composite and other packaging materials can be used. According to different raw materials and supporting facilities, different metrological verification equipment can complete the automatic feeding vacuum packaging bags of granules, powders, small pieces, liquids, canned soft fruits, small toys, hardware and other commodities.

As we all know, the food vacuum packaging machine is a dust-free, fully enclosed pipeline conveying equipment that uses vacuum suction to convey granular or powdered materials. It uses the pressure difference between the vacuum and the ambient space to form an air flow in the pipeline, drive the powder material to move, and complete the powder conveying process. The vacuum powder feeder is also a vacuum powder feeder in Shijiazhuang. It is a dust-free and closed pipeline conveying equipment that uses vacuum suction to convey granular and powdered materials.

my country has introduced advanced vacuum technology from abroad and has continuously improved it. It is currently widely used in light and heavy industries such as chemical, pharmaceutical, food, metallurgy, building materials, and agricultural and sideline products.
