With the continuous improvement of people's living standards, the demand for various convenience foods has also increased, which has further stimulated the rapid development of my country's food packaging industry. Vacuum packaging machine is one of the fastest-growing packaging machinery and has broad development prospects. There are many types of vacuum packaging machines. Let me introduce you to vacuum packaging machines.
Definition: People often put the packaged objects on the outside of the vacuum chamber to complete the vacuum packaging equipment called vacuum packaging machine.
Principle: The vacuum packaging machine puts the air nozzle into the packaging bag of the packaged object, evacuates the air, exits the air nozzle, and then completes the sealing.
1. Part of the air (oxygen) in the packaging container is excluded, which can effectively prevent food spoilage.
2. The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging content substances, which can avoid food weight loss and loss of taste, and prevent secondary pollution.
3. The gas inside the vacuum packaging container has been removed, which accelerates the heat conduction, which can improve the efficiency of thermal sterilization, and also avoid the packaging container rupture due to the expansion of gas during thermal sterilization.
In the food industry, the application of vacuum packaging is very common. Various cooked products such as chicken legs, ham, sausages, etc.; pickled products such as various pickles, soy products, preserved fruits and other foods that need to be kept fresh are increasingly using vacuum packaging. Package. Vacuum-packed food has a long shelf life, greatly extending the shelf life of food.
When choosing a vacuum packaging machine, you should not simply choose the model according to the model. Generally speaking: because the food (packaging) produced by each user is not the same, the packaging size is different.
Composition: vacuum pump, motor, vacuum chamber, sealing strip, plexiglass plate cover, air bag, solenoid valve, etc.
1. The way of feeding and discharging materials: forward and right out.
2. The compression vacuum packaging machine adopts the fixed instant heating method of the hot box to save energy.
3. Special electric heating arrangement, even heat distribution.
4. The body is compact and occupies a small area.
5. It is suitable for small batch production and medium production. It can cooperate with assembly line operation and improve the efficiency of vacuum packaging machine.Water Removal Unit
