Filling Machine Filling Method

1) atmospheric pressure method is also known as normal pressure method, that is, under normal pressure, the liquid material to rely on self-weight flow into the packaging container. Most of the free flow of gas-free liquid can be filled with this method, such as liquor, wine, milk, soy sauce, vinegar and so on.

(2) isobaric pressure equalization method, also known as pressure gravity filling method, that is, higher than atmospheric pressure conditions, the first charge of the packaging container, so that the formation of the tank with the same pressure, and then rely on the irrigation The weight of the liquid material flows into the packaging container. This method is generally used for gas-containing beverages such as beer, soft drinks, sparkling wine and other filling. Filling with this method can reduce the loss of CO2 contained in these products and prevent excessive foaming during filling and affect product quality and quantitative accuracy.

(3) vacuum method vacuum method is below the atmospheric pressure under the conditions of filling, can be carried out in two ways:

(A) the pressure difference vacuum that is in the tank at atmospheric pressure, only the packaging container to make a vacuum, the liquid material to rely on the tank and the pressure difference between the container to produce flow to complete the filling, the domestic This method is more commonly used.

(B) the gravity vacuum is the vacuum inside the tank, the packaging container is first evacuated to form a vacuum equal to that in the tank, and then the liquid material flows into the packaging container by gravity, because the structure is more complicated and less domestic use. Vacuum filling a wide range of applications, it is suitable for filling a slightly larger viscosity of liquid materials, such as oil, syrup and so on. Also applies to filling vitamins with liquid materials, such as vegetable juice, fruit juice, etc., the formation of a vacuum inside the bottle means to reduce the liquid material and air contact to extend the shelf life of the product, vacuum method is also suitable for filling toxic Materials, such as pesticides, etc., to reduce the spill of toxic gases, improve working conditions.
