Liquid packaging machine is the packaging equipment for liquid products, such as beverage filling machine, dairy filling machine, viscous liquid food packaging machine, liquid cleaning products and personal care products packaging machine, etc. all belong to the category of liquid packaging machine.

It is suitable for soy sauce, vinegar, fruit juice, milk and other liquids. 0.08mm polyethylene film is used. Its molding, bag making, quantitative filling, ink printing, sealing and cutting are all automatic. The film is disinfected by ultraviolet before packaging, which meets the requirements of food hygiene.

Working principle: atmospheric pressure filling machine is under atmospheric pressure by liquid weight filling. This kind of filling machine can be divided into timing filling and constant volume filling, which is only suitable for filling low viscosity liquid without gas, such as milk, wine and so on.

The pressure filling machine can be divided into two types: one is that the pressure in the liquid storage tank is equal to that in the bottle, and the liquid flows into the bottle by its own weight, which is called equal pressure filling; the other is that the pressure in the liquid storage tank is higher than that in the bottle, and the liquid 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 is in the bottle pressure is lower than atmospheric pressure for filling.
