The categories of filling for beverage filling machines are:
Beverage filling machine can be divided into ordinary pressure filling machine, pressure filling machine and vacuum filling machine according to the filling principle.
The ordinary pressure filling machine is filled by liquid self-loading under atmospheric pressure. This type of filling machine is divided into two types: regular filling and fixed capacity filling. It is only suitable for filling liquids with low viscosity and no gas such as milk, wine, pure water, drinking water, and juice drinks.

The pressure filling machine is filled at a pressure higher than the atmospheric pressure, and can also be divided into two types: one is that the pressure in the tank is equal to the pressure in the bottle, and it is filled with liquid self-weight into the bottle, called isopressure filling; The other is that the pressure in the tank is higher than the pressure in the bottle, and the liquid flows into the bottle by pressure difference. This method is often used in high-speed production lines. The pressure filling machine is suitable for liquid filling containing gas, such as beer, soda, champagne, carbonated drinks, soda, etc.
Vacuum filling machine is to fill the bottle under pressure lower than atmospheric pressure. This kind of filling equipment has a simple structure and high efficiency. It can adapt to the viscosity of the material in a wide range, such as oil, syrup, and fruit wine.
