With the continuous improvement of people's living standards, the demand for various convenience foods has also increased greatly, which has recently stimulated the rapid development of China's food packaging industry. Vacuum packaging machine is one of the fastest developing packaging machines and has broad development prospects. There are many types of vacuum packaging machines. Let's introduce the vacuum packaging machine.
People often put the packaged goods on the outside of the vacuum chamber to complete the vacuum packaging equipment called vacuum packaging machine.
The vacuum packaging machine is placed in the package of the packaged object through the suction nozzle, evacuates the air, exits the suction nozzle, and then completes the sealing.
1. Exclude part of the air (oxygen) in the packaging container, which can effectively prevent food from spoiling.
2, the use of barrier (airtight) excellent packaging materials and strict sealing technology and requirements, can effectively prevent the exchange of packaging content, can avoid food weight loss, loss of taste, but also prevent secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, which accelerates the heat conduction, which can improve the heat sterilization efficiency and avoid the rupture of the packaging container due to the expansion of the gas during the heat sterilization.
In the food industry, vacuum packaging applications are very common, a variety of cooked products such as chicken legs, ham, sausages, etc.; pickled products such as a variety of pickles and soy products, preserved fruit and other foods that need to be fresher and more vacuum package. The vacuum-packed food has a long shelf life and greatly extends the shelf life of the food.
When choosing a vacuum packaging machine, you should not simply select the model according to the model. Generally speaking, because the foods (packages) produced by each user are not the same, the package size is not uniform.
Vacuum pump, motor, vacuum chamber, sealing strip, plexiglass plate cover, air bag, solenoid valve, etc.
