Due to the wide range of liquid filling machinery, there are many types of liquid filling machinery, and there are corresponding filling equipment according to different classifications.
Liquid filling machines can be divided into atmospheric filling machines, pressure filling machines, vacuum filling machines, and automatic quantitative liquid filling machines according to the filling principle.
According to the type of filling operation, it can be divided into automatic liquid filling machine and semi-automatic liquid filling machine.
According to the filling type, it can be divided into diluted liquid filling machine, thick liquid filling machine and oil filling machine.
Atmospheric filling machine
Atmospheric filling machine is filled by liquid's own weight under atmospheric pressure. This type of filling machine is divided into two types: timing filling and constant volume filling, which are only suitable for filling low-viscosity and gas-free liquids such as milk and wine.
Pressure filling machine
The pressure filling machine is used for filling at higher than atmospheric pressure. It can also be divided into two types: one is that the pressure in the liquid storage tank is equal to the pressure in the bottle, and the liquid flows into the bottle by its own weight. Isobaric filling; the other is that the pressure in the liquid storage cylinder 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 filling liquids containing gas, such as beer, soda, champagne, etc.
Vacuum filling machine
The vacuum filling machine is filled under the pressure in the bottle lower than the atmospheric pressure. This type of filling machine has a simple structure, high efficiency, and a wide range of adaptability to the viscosity of materials, such as oils, syrups, and fruit wines.
Quantitative (liquid) filling machine
Product name: Automatic quantitative liquid filling machine
