The Working Principle Of Automatic Liquid Packaging Machine

Automatic liquid packaging machine is filled by the weight of the liquid under atmospheric pressure. This type of filling machine is divided into two types: timed filling and constant volume filling. It is only suitable for filling low-viscosity and gas-free liquids such as water, milk, and wine. The pressure filling machine is filled at a pressure higher than atmospheric pressure, and 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 filling is performed 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 tank is higher than the pressure in the bottle, and the liquid flows into the bottle by the pressure difference. This method is mostly used in high-speed production lines. The pressure filling machine is suitable for filling liquids containing gas, such as beer, soda, champagne, etc. The vacuum filling machine fills the bottle when the pressure in the bottle is lower than atmospheric pressure.
