What is the structural principle of a single-chamber vacuum packaging machine ? Generally speaking, its whole structure is composed of a plexiglass cover, a vacuum chamber, a body electrical control system, a vacuum system and the like. However , in the work of the single-chamber vacuum packaging machine , the important thing is the vacuum system, which is composed of the exhaust valve, the inflation valve, the bleed valve and the like, which is equivalent to the actuator.

When the user puts the item to be packaged into the vacuum chamber of the single-chamber vacuum packaging machine, the vacuum pump can be pumped from the vacuum chamber after the start of the vacuum pump. When the predetermined vacuum setting is reached, the vacuum pump stops, and then turns to the next. A heat sealing process.
Generally, the lower working chamber of the small vacuum packaging machine is provided with a hot-press sealing device, and the heating component is a nickel-chromium belt, and the device is absolutely insulated between the bakelite hot pressing body and the vacuum chamber, and the bakelite hot pressing frame is closely attached to the air bag, and is heat-sealed. The front airbag is in a vacuum state.
When the single-chamber vacuum packaging machine performs heat sealing, the airbag passes through the electromagnetic valve to generate a pressure difference through the electromagnetic valve, so that the airbag becomes large, the heating head (nickel-chromium belt) is lifted, the sealing pocket is pressed, and heating is performed at the same time, and then completed. The sealing process. It can be said that the food after packaging by the single-chamber vacuum packaging machine has a long shelf life, is not easy to deteriorate, and can also improve the product grade.
In general, the single-chamber vacuum packaging machine is only one packaging studio. Its working principle is a glass cover with a working studio. Before starting to package the product, put the product to be sealed and put on the cover. The machine starts. jobs. After the pumping and sealing process is completed, the sealed product is taken out, the product to be sealed is continuously placed, and the lid is closed, and the cycle is repeated.
