Beverage filling machine can be divided into normal pressure filling machine, pressure filling machine and vacuum filling machine according to filling principle.
The atmospheric filling machine is filled with the liquid's own weight under atmospheric pressure. This type of filling machine is divided into two types of time filling and constant volume filling. It is only suitable for filling liquids with low viscosity without gas, such as milk, wine, pure water, juice drinks and so on.
Pressure filling machine is filled under the atmospheric pressure, it can also be divided into two types: one is that the pressure in the tank is equal to the pressure in the bottle, and the bottle is filled with the liquid and flows into the bottle and is called Equal pressure filling; the other is that the pressure in the reservoir is higher than the pressure in the bottle, the liquid flows into the bottle by the pressure difference, high-speed production lines use this method. Pressure filling machine is suitable for liquid filling with gas, such as beer, soft drinks, champagne, carbonated drinks, soda and so on.
The vacuum filling machine fills the bottle under pressure below atmospheric pressure;
The filling machine has a simple structure and high efficiency, and has a wide range of viscosity adaptability to materials, such as oil, syrup, wine, and the like.
