This model is newly designed product of my factory which not only contains the features of common models but also has new advantages. The machine body can be easily lift up so it is very convenient for daily maintenance. This machine can pack grain ( Food, local specialty, medicine, electronics, hardware..), powder ( coffee, wheat…), paste( ketchup, honey, seafood…). The main principle is the air in bag is inhaled and the bag is sealed at the same time. This can constrain the propagate of organism, food oxidize and rotten which can prolong the valid time. Some loose products are easy to transport and store after packed.

1  Switch gas, when the valve 1 and valve 4 is closed, the valve 2 is opened, the mechanical vacuum pump on I vacuum container, air flows through the pre vacuum suction pipe; when the vacuum valve 2 closed, valve 4 is opened, the mechanical pump can separate diffusion pump vacuum; when the vacuum valve 1 and valve 4 open at the same time, the diffusion pump and mechanical pump can work at the same time, the container to be evacuated, the air flows through the diffusion pump. Visible, the role of the valve in this operation is to switch the gas path, change the flow path of air flow.

2  The size of the air flow control, vacuum regulator in Figure 1, the control valve 1, the valve cover opening angle can adjust the gas flow through the pipeline; close the valve 2 and valve 4, through the discharge valve 3 to the mechanical pump entrance III put into the atmosphere; through the discharge valve 5 can adjust the vacuum container degree.

3  Quantitative inflation, have a certain volume of the hole in the glass on the plunger, when the hole to the right and the high-pressure gas cylinders connected, the holes can be filled with high-pressure gas; when the high vacuum valve to the left and the vacuum vessel is communicated, put the volume of high-pressure gas into the container, so that the quantitative inflation will.
