Beverage processing production line: Three canning methods and characteristics of beverage filling machines

Beverage filling machines are a subclass of packaging machinery used for producing bottled, barreled mineral water, and other drinking water. It consists of cleaning, filling, and sealing. It is an ideal equipment for producing mineral water and purified water. Next, let's take a look at the three commonly used canning methods:

1. Atmospheric pressure method
The normal pressure method, also known as the pure gravity method, means that under normal pressure, liquid materials flow into packaging containers by their own weight. Most free flowing liquid materials without gas can be filled in this way, such as Baijiu, fruit wine, milk, soy sauce, vinegar, etc.
2. Isobaric method
The isobaric method, also known as the pressure gravity filling method, is to first inflate the packaging container under high atmospheric pressure, so that the air pressure is equal to the air pressure inside the storage tank, and then rely on the weight of the filling liquid flowing into the packaging container. This method is commonly used for filling carbonated beverages, such as beer. This method can reduce the loss of CO2 contained in this type of product and prevent excessive bubbles from affecting product quality and quantitative accuracy during the filling process.
3. Vacuum method
The vacuum method is used for filling under conditions below atmospheric pressure and can be carried out in two ways:
① Differential pressure vacuum
The storage tank is in a normal pressure state, only vacuuming the packaging container to form a vacuum, and filling is completed by relying on the pressure difference between the storage tank and the container to be filled. This method is commonly used in China.
② Gravity vacuum
The liquid storage tank is inside a vacuum packaging container. It is first vacuumed to form a vacuum degree equal to the liquid storage tank, and then the liquid material flows into the packaging container by its own weight. Due to its complex structure, it is rarely used in China. Vacuum filling is widely used and suitable for filling liquid materials with slightly higher viscosity, such as oil, syrup, etc.
During the use of the beverage Filling Machine, it is necessary to constantly check and add oil mist, and the oil must be kept at one-third position. The discharge piston and the sealing ring cylinder at the lower end of the discharge need to be replaced in a timely manner after wear. When cleaning, try to avoid being scratched by sharp and hard objects. If there is contamination, you can wipe it with alcohol and make sure to keep your whole body clean.
