Vacuum packaging machine
can automatic extraction of air inside the bag, arrived in booking after vacuum sealing process.
Yi ke and blended into nitrogen or other gases, then end of the sealing process.
Vacuum packing machine
is often used for food profession, because after vacuum packing in the future, food antioxidant, and then arrived in long time preservation.
introduce the classification and operation principle of the vacuum packaging machine
, packaging container products, smoke to the air inside the container, arrived in booking vacuum degree, and the end of the sealing process machine called a vacuum packaging machine.
Vacuum packing machine is first used for packing what a brief products oxidation, mildew, perhaps a brief be affected with damp be affected with damp metamorphosis, in order to prolong the using time of the product or perhaps instruments such as rust, avoid fine parts such as pickle, sausage packaging.
Vacuum packaging film perhaps composite materials should have use must air tightness and pressure resistance and mechanical adaptability, and so on.
Relatively more vacuum packaging machine, generally can be divided into: mechanical kneading type, intubation, chamber, thermal type, etc.
Mechanical kneading type vacuum packing machine as shown in figure for mechanical kneading type vacuum packing principle diagram.
On both sides of the bag after filling, in its first sponge items such as elastic sweep of air inside the bag, then the sealing packing, called mechanical kneading type.
This way the brief, but low vacuum, vacuum degree for different occasions.
food vacuum packaging machine process: vacuum, vacuum chamber cover, vacuum pump, vacuum chamber vacuum is preliminary, also with the vacuum packing bag, vacuum gauge pointer rise, arrived at the rated vacuum (
Is first time relay ISJ control)
Vacuum pump stop operation, the vacuum stopped.
In a vacuum, homework together, two preliminary work, the 3-way magnet valve (IDT vacuum heat sealing, hot pressing stick to in situ.
heat sealing: outside air to pass into the hole and then into the hot sealing chamber, using vacuum chamber and hot sealing between the air chamber pressure is different, make the heat sealing chamber inflatable swell, and make it on the hot pressing frame to move down, together with the pressure mouth;
When heat sealing transformer preliminary work, sealing operations;
In this together, time relay 2 sj also preliminary work, action after a few seconds, heat sealing end.
gas back: 2 dt through two two-way solenoid valves, air into the food vacuum packaging machine vacuum chamber, vacuum gauge pointer back to zero, hot-pressing relying on the reset spring return, vacuum chamber open cover.
circulation, move the vacuum chamber to another vacuum chamber, namely into the next process, around two rooms replacement operation, cycling.
