What is vacuum pumping machine?

What is vacuum pumping machine? Pre-purchase precautions for external vacuum packaging machine:

First, the definition of external pump vacuum packaging machine:

People often put the packaged goods on the outside of the vacuum chamber to complete the vacuum packaging equipment called external vacuum packaging machine. Outlet vacuum packaging machines are designed primarily for vacuum packaging of larger packages.

Second, the principle of external vacuum packaging machine:

Different from the structure of the internal vacuum packaging machine, the external vacuum packaging machine is placed in the packaging bag of the packaged object by means of a suction nozzle, evacuating the air, exiting the suction nozzle, and then completing the sealing. Outlet vacuum packaging machines generally have 1~4 suction nozzles. The power source of the sealing line is generally a cylinder or a motor.

Third, the classification of external pump vacuum packaging machine:

The external pumping vacuum packaging machine is divided into a horizontal vacuum pumping machine and a vertical vacuum pumping machine according to the location of the packaging. The horizontal packed vacuum packaging machine is horizontally placed; the vertical external vacuum packaging machine is vertically placed. Horizontal vacuum packers are more common in the market.

Fourth, when purchasing external vacuum packaging machine should pay attention to the content

When choosing an external vacuum packaging machine, it is not enough to simply select the model according to the model. In general, since the food (packages) produced by various users is not the same, the packaging size is not the same, and the technical level of vacuum packaging is required. Different, work efficiency requirements are different (production size, etc.), but should be based on the user's own product characteristics (including: liquid, solid, powder, gelatinous, semi-liquid, pickled salted products, cooked meat, seafood, etc.), The size of the bag (including the width of the bag mouth, the length of the bag in the longitudinal direction, and the height (thickness) of the packaged item to determine what model is suitable for the user.) The main basis for the user to determine the model is the package Machine sealing length, double-row spacing, the maximum available height of the vacuum chamber, the overall production efficiency and so on.

Fifth, the scope of application of vacuum pumping machine

â—†Vacuum packing machine is used for vacuum packaging of fabrics and cotton wool products to reduce the packing volume and save logistics costs.

â—† Vacuum packaging for all types of electronic products (semiconductors, circuit boards, electronic finished products, etc.) and machined metal parts to prevent moisture and oxidation.

â—† Vacuum packaging for seafood, fruits, tea, salted products, and soy products in foods to prevent oxidative deterioration and extend the shelf life

Sixth, outside pumping vacuum packaging machine technical characteristics

â—† Japan and South Korea's leading technology integrates simple sealing, vacuum and other functions.

â—† The vacuum packing machine only draws the gas inside the bag and the speed is fast (it takes only 2 to 3 seconds to complete).

â—† Stainless steel just adjust the height according to the thickness of the object to be packaged. And does not impose restrictions on the dimensions of the product,

Therefore, this machine is most suitable for extra large or irregular items.

â—† Sealing pressure is provided by a variable-diameter cylinder with a large bore diameter. The sealing pressure is large, completely changing the phenomenon that the traditional packaging seal is not strong.

â—† Small footprint (only 0.5m2), and only one person can operate. There is a simple storage box for easy storage of small items. The bottom is equipped with casters and is free to move.
