Liquid filling machine, which package all kinds of material such as liquid, paste etc. But do you know liquid filling machine working principle?
Based on the different filling pressure, liquid filling machine can be classified into ordinary pressure filling, vacuum filling and pressure filling.
- Ordinary pressure liquid filling adopts gravity-flowing filling based on its own weight of the liquid. Greater requirements should be done for the viscosity and gas-bearing of the liquid. Its main filling material is wine and milk.
- Vacuum liquid filling is proceeding when the pressure of the bottle is below the atmospheric pressure. With simple structure and high efficiency, this machine is usually used for high viscosity liquid such as oil, syrup, etc.
- Pressure filling works when it is above the atmospheric pressure, which can be classified into two parts. One is called equal air pressure filling which means the liquid flows into the bottle based in its own weight when the pressure of the liquid reservoir is equal to the bottle. Another is called high pressure filling which means the liquid flows into the bottle based on the pressure difference when the pressure of the liquid reservoir is high than the bottle.
Of course, the filling machine working principles of different types of filling machines are different. For example, semi-automatic machines and automatic machines have different principles. If you want to know more details, please contact us.
