Water filling machine can be divided into atmospheric pressure filling machine, pressure filling machine and vacuum filling machine.
Vacuum filling machine:Vacuum filling machine in the bottle under the pressure of less than atmospheric pressure filling. This water filling machine structure is simple, high power, the viscosity of the material used in a wider scale, such as oil, syrup, wine, etc.are applicable.
Atmospheric pressure filling machine：Atmospheric pressure filling machine in the atmospheric pressure by liquid weight filling. This type of water filling machine is divided into punctual filling and constant volume filling two, only for filling low viscosity non-gas liquid such as milk, wine and so on.
Pressure filling machine：Pressure filling machine is higher than atmospheric pressure for filling production, can be divided into two categories: First, the pressure in the tank and the pressure in the bottle flat, relying on the liquid weight into the bottle and filling.The second is the pressure inside the tank is higher than the pressure in the bottle, the liquid pressure into the bottle by the pressure, high-speed production line and more use of this category. Pressure filling machine for gas-filled liquid filling,such as beer,soft drinks,champagne and so on.
