The principle of filling machine you know?

Filling machine filling method:

1) Normal pressure method
Normal pressure method, also known as pure gravity 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 material can be filled with this method, such as liquor, wine, milk, soy sauce, vinegar and so on.
(2) isobaric method
Equal pressure 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 infusion of pouring material into the weightInside the packaging container.This method is generally used for gas-containing beverages such as beer, soft drinks, sparkling wine and other filling.The filling of this method can reduce the loss of CO2 contained in such products and prevent excessive foaming during filling and affect product quality and quantitative accuracy.
(3) Vacuum method
Vacuum method is carried out under the conditions of less than atmospheric pressure, can be carried out in two ways:
(A) Differential pressure vacuum type
That is, the tank is at atmospheric pressure, only the packaging container to make a vacuum, liquid material to rely on the tank and the pressure difference between the container to produce flow to complete the filling, domestic this method is more commonly used.
(B) gravity vacuum type
That is, the tank is in a vacuum, the packaging container is first pumped to form a vacuum equal to that in the tank, and then the liquid material flows into the packaging container by its own weight, because the structure is more complicated and less domestic.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 suitable for filling vitamins containing liquid materials, such as vegetable juice, fruit juice, etc., the bottle to form a vacuum means that the liquid material to reduce the contact with the air to extend the shelf life of the product, vacuum method is also suitable for filling toxicMaterials such as pesticides, etc., to reduce the spill of toxic gases, improve working conditions.
(4) pressure method
The use of mechanical pressure or pressure, the irrigation material will be squeezed into the packaging container, this method is mainly used for filling thick viscous materials, such as filling tomato sauce, meat emulsion, toothpaste, balsam and so on.And sometimes can be used for soft drinks a soft drink filling, then rely on the pressure of the water itself directly into the bottle without inflatable pressure, which increased the filling speed, the formation of the bubble because of the colloid is still easy to disappear,On the filling quality have a certain impact.
In this paper, the filling method of filling machine is determined:
For the general consumption of liquid materials such as bottled milk, bottled alcohol, carbonated drinks, etc., can be used to fill the pressure method, vacuum filling method, but taking into account the cost of isobaric filling method can effectively reduce the loss of CO2,To maintain the quality of gas-containing drinks, and to prevent excessive filling in the bubble, to ensure accurate filling measurement.Therefore, this paper uses isobaric filling method.
The bottle in the filling machine in turn: 1, into the air, 2, into the liquid back to the gas; 3, stop the liquid; 4, remove the remaining liquid 4 steps.At the same time the production line of a variety of detection status sensors all access to the PLC, the PLC according to the sensor detection status through the preparation of a good program to control the entire system work.
