What are the common filling methods for beer filling machines?

Beer filling machine, as its name implies, is mainly used for beer filling. What are the main filling methods of beer filling machines? Let's take a look. Due to the differences in physical and chemical properties of liquid materials, there are also different requirements for filling. Liquid materials are poured into packaging containers by liquid storage devices. Beer filling machines often adopt the following methods. I. Normal pressure filling normal pressure filling refers to a filling method in which the self-weight of the liquid to be filled directly flows into the packaging container under atmospheric pressure. The technological process of normal pressure filling is as follows: 1. Liquid inlet and exhaust, I . e. liquid material enters the container, and the air in the container is discharged at the same time; 2. Stop liquid feeding, I . e. when the liquid in the container meets the quantitative requirements, the liquid feeding will automatically stop; 3. Eliminate the residual liquid, that is, eliminate the residual liquid in the exhaust pipe. The atmospheric pressure method is mainly used for filling viscous and non-gaseous liquid materials such as milk, liquor, soy sauce, syrup, etc. Second, isobaric filling, isobaric filling is to inflate the packaging container with compressed air from the upper air chamber of the liquid storage tank so that the pressures of the two are close to equal, the filling method in which the liquid material is then fed into the packaging container by its own weight. The technological process of isobaric filling is as follows: 1. Inflation and isobaric pressure; 2, liquid return gas; 3. Stop feeding; 4. Release the pressure, that is, release the residual compressed gas in the bottleneck into the atmosphere, so as not to cause a large amount of bubbling due to sudden depressurization in the bottle, affecting the packaging quality and quantitative accuracy. Isobaric method is suitable for filling aerated beverages such as beer and soda water, which can reduce the loss of carbon dioxide contained. Three, vacuum filling method, vacuum filling method is a method of filling under the condition of lower than atmospheric pressure. It has two basic ways: one is pressure vacuum type, that is, the inside of the liquid storage tank is in a normal pressure state, and only the inside of the packaging container is pumped to form a certain degree of vacuum, the liquid flows into the packaging container and completes the filling by relying on the pressure difference between the two containers; The other is gravity vacuum type, that is, the liquid storage tank and the packaging container are in a nearly equal vacuum state, and the liquid material flows into the container by its own weight. At present, pressure vacuum is often used in China. Its equipment is simple and reliable. The technological process of vacuum filling is as follows: 1. Vacuum the bottle; 2. Liquid intake and exhaust 3. Stop liquid intake; 4. The residual liquid flows back, I . e. the residual liquid in the exhaust pipe flows back to the liquid storage tank through the vacuum chamber. The vacuum method is suitable for filling liquid materials with lower viscosity (Such as oils, syrups, etc), Vitamin-containing liquid (Such as vegetable juice, fruit juice, etc)And toxic liquid (Such as pesticides, etc). This method can not only improve the filling speed, but also reduce the contact and effect between the liquid material and the residual air in the container, so it is beneficial to prolong the shelf life of a certain series of products. In addition, it can also limit the escape of gas and liquid, thus improving the operating conditions. However, it is not suitable for filling liquid containing aromatic gas, because pumping will increase the loss of liquid fragrance. Four, pressure method filling, pressure method filling is to control the reciprocating motion of the piston by means of mechanical or pneumatic and hydraulic devices, and liquid materials with higher viscosity are sucked into the piston cylinder from the storage cylinder, then forced into the container to be filled, this method is sometimes used for filling beverages such as gas, because it does not contain colloidal substances, the formed foam is easy to disappear, therefore, the filling speed can be greatly improved by directly pouring the gas pressure itself into the bottle without pre-inflation. Five, siphon filling application, siphon principle makes the liquid material through the siphon from the liquid storage tank is sucked into the container until the two liquid levels are equal. This method is suitable for filling liquid materials with low viscosity and no gas. The equipment has simple structure but low filling speed. To sum up, the filling methods of beer filling machines mainly include normal pressure filling, equal pressure filling, vacuum filling, pressure filling and siphon filling. The technological scope of beer filling machine refers to its ability to meet different production requirements. The wider the process range, the more the utilization rate of the equipment can be improved, and the multi-purpose of one machine can be realized, that is, the same equipment can be used to fill various materials and various specifications. Therefore, in order to meet the production requirements of multiple varieties and specifications in the beverage and beverage industries, filling machines with as wide a technological range as possible should be selected. : Beer filling machine
