Introduction to the filling method of the filling machine
Many people do not understand the correct use of the filling machine, the filling method of the filling machine:

(1) Atmospheric pressure method

Atmospheric pressure method is also called pure gravity method, that is, under normal pressure, the liquid material flows into the packaging container by its own weight. Most of the free-flowing gas-free liquid materials can be filled with this method, such as white wine, fruit wine, milk, soy sauce, vinegar, etc.

(2) Isobaric method

The equal pressure method is also called the pressure gravity filling method, that is, under the condition of higher than atmospheric pressure, the packaging container is first inflated to form an air pressure equal to that in the liquid storage tank, and then the material to be filled flows in by its own weight Inside the packaging container.

(3) Vacuum method

The vacuum method is filled under the condition of lower than atmospheric pressure, and it can be carried out in two ways.

(A) Differential pressure vacuum type

That is, the liquid storage tank is under normal pressure, and only the packaging container is evacuated to form a vacuum. The liquid material flows through the pressure difference between the liquid storage tank and the container to be filled to complete the filling. This method is more commonly used in China.

(B) Gravity vacuum type

That is, the liquid storage box is in a vacuum. The packaging container is first evacuated to form a vacuum equal to that in the liquid storage box, and then the liquid material flows into the packaging container by its own weight. Due to its complex structure, it is less used in China. Vacuum filling has a wide range of applications, and it is suitable for filling liquid materials with a slightly higher viscosity, such as oils and syrups.

(4) Pressure method

Use mechanical pressure or air pressure to squeeze the filled material into the packaging container.
