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. The vacuum packaging machine is one of the relatively fast-developing packaging machinery and has a broad prospect for development. There are many types of vacuum packaging machines. Let me introduce you to vacuum packaging machines.
principle:
The vacuum packaging machine is put into the packaging bag of the package through the suction nozzle, evacuates the air, exits the suction nozzle, and then completes the sealing.
Features:
1. Part of the air (oxygen) in the packaging container is eliminated, which can effectively prevent food from spoiling.
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 contents, which can avoid food weight loss, loss of taste, and secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, accelerating the heat transfer, which can improve the efficiency of heat sterilization and avoid the packaging container from rupturing due to the expansion of gas during heat sterilization.
In the food industry, vacuum packaging is very common. Various cooked products such as chicken legs, ham, sausages, etc.; preserved products such as various pickles, soy products, preserved fruits and other foods that need to be kept fresh are increasingly using vacuum package. Vacuum-packed food has a long shelf life, which greatly extends the shelf life of the food.
Precautions:
When choosing a vacuum packaging machine, you should not simply select the model based on the model. In layman's terms: Since the food (package) produced by each user is not the same, the packaging size is different.
composition:
Vacuum pumps, motors, vacuum chambers, sealing strips, plexiglass plate covers, air bags, solenoid valves, etc.
Technical features:
1. Feeding and discharging method: forward and right out
2. The compression vacuum packaging machine adopts a hot box fixed instant heating method to save energy
3. Special electric heating arrangement, even heat distribution.
4. The body is small and the floor space is small
5. Suitable for small batch production and medium volume production. Vacuum packaging machine that can cooperate with assembly line operation to improve efficiency
6. Using original imported spare parts from Taiwan, Japan and South Korea, the performance is stable and reliable
