Filling machines can be divided into atmospheric pressure filling machines, pressure filling machines, liquid filling machines, oil filling machines, paste filling machines, sauce filling machines, granular slurry filling machines, powder filling machines, large bucket water filling machines, and vacuum filling machines according to the filling principle.

atmospherical pressure filling machine

The atmospheric pressure filling machine is used to fill the liquid by its own weight under atmospheric pressure. This kind of filling machine can be divided into fixed time filling and fixed volume filling. It is only suitable for filling low viscosity liquid without gas, such as milk, Baijiu, mineral water, etc.

Pressure filling machine

Filling is carried out at a pressure higher than atmospheric pressure, which can also be divided into two types: one is when the pressure in the storage tank is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight for filling, which is called isobaric filling; Another method is that the pressure in the storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle through the pressure difference. This method is commonly used in high-speed production lines. The pressure filling machine is suitable for filling liquids containing gases, such as beer, soda, champagne, etc.

vacuum filler

Filling is carried out at a pressure lower than atmospheric pressure in the bottle. This filling machine has a simple structure, high efficiency, and a wide range of adaptability to the viscosity of materials, such as oils, syrups, fruit wine, etc.
