Working principle of liquid packaging machine

by admin

the atmospheric pressure filling machine is filled by liquid self weight under atmospheric pressure. This kind of filling machine is divided into regular filling and constant volume filling. It is only suitable for filling low viscosity liquid without gas, such as milk, wine, etc
the pressure filling machine is used to fill at a pressure higher than the atmospheric pressure, which can also be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the filling is carried out by the liquid flowing into the bottle by its own weight, which is called isobaric filling; The other is that the pressure in the liquid storage cylinder is higher than that in the bottle, and the liquid flows into the bottle by pressure difference. This method is mostly used in high-speed production lines. Pressure filling machine is suitable for filling liquid containing gas, such as beer, soda, champagne, etc
the vacuum filling machine is used for filling when the pressure in the bottle is lower than the atmospheric pressure
