Due to the wide range of liquid filling machinery, there are many kinds of liquid filling machinery, according to different classification, there are corresponding filling equipment.
According to the filling principle, liquid filling machine can be divided into atmospheric pressure filling machine, pressure filling machine, vacuum filling machine and automatic quantitative liquid filling machine.
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 type of filling, it can be divided into dilution liquid filling machine, concentrated liquid filling machine and oil filling machine, etc.
atmospherical pressure filling machine
Atmospheric pressure filling machine is under atmospheric pressure by liquid self weight filling. This kind of filling machine can be divided into two kinds: regular filling and constant volume filling. It is only suitable for filling liquid with low viscosity and no gas, such as milk and wine.
Pressure filling machine
The pressure filling machine can be divided into two types: one is that the pressure in the liquid storage tank is equal to the pressure in the bottle, and it is filled by the self weight of the liquid into the bottle, which is called equal pressure filling; the other is that the pressure in the storage tank is higher than the pressure in the bottle, and the liquid body flows into the bottle by the pressure difference. This method is often used in high-speed production lines. Pressure filling machine is suitable for filling liquid containing gas, such as beer, soda, champagne, etc.
Vacuum filling machine
Vacuum filling machine is to fill the bottle under the pressure lower than atmospheric pressure. This kind of filling machine has simple structure and high efficiency, and can be used in a wide range of viscosity of materials, such as oil, syrup, fruit wine, etc.
Quantitative (liquid) filling machine
