The vacuum tumbler is a tool in the field of meat processing machinery. The function is directly related to the quality of the product. As people's material level is increasing, the vacuum tumbler has also developed some standards to purify the uneven market.

The vacuum packaging of a vacuum tumbler is a packaging technique in which an article is placed in a gas-tight container and evacuated before the container is sealed, so that the sealed container is substantially free of air for operation. The vacuum packaging of the vacuum tumbler can be divided into heating exhaust and suction sealing according to different exhaust gases. The heated exhaust gas is heat-treated before the food is filled, and the moisture in the food is evaporated to the air by the heat rise and contraction of the air, and then sealed.

The air-tight seal is to form a certain vacuum in the packaging container, and then the air in the packaging container is drawn out by a vacuum pump on a vacuum packaging machine, and after a certain degree of vacuum is reached, it is sealed immediately, so that the package is formed into a vacuum state. Compared with the former method, the air-tight seal can effectively reduce the heating time of the food and better protect the color and aroma of the food, so the pumping and sealing ratio is wider than that of the hot exhaust.
