What is a liquid packaging machine?
Liquid filling machines can be divided into atmospheric filling machines, pressure filling machines and vacuum filling machines according to the filling principle.
Liquid packaging machines are packaging equipment for packaging liquid products, such as beverage filling machines, dairy filling machines, viscous liquid food packaging machines, liquid cleaning products and personal care packaging machines, etc., all belong to the category of liquid packaging machines.
It is suitable for soy sauce, vinegar, juice, milk and other liquids. The 0.08mm polyethylene film is used. Its forming, bag making, quantitative filling, ink printing, sealing and cutting are all automatically performed. The film is UV disinfected before packaging, which is in line with food Hygiene requirements. working principle
Atmospheric filling machine is filled by liquid's own weight under atmospheric pressure. This type of filling machine is divided into two types: timing filling and constant volume filling, which are only suitable for filling low-viscosity and gas-free liquids such as milk and wine.
The pressure filling machine is used for filling at higher than atmospheric pressure. It 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 liquid flows into the bottle by its own weight. Isobaric filling; the other is that the pressure in the liquid storage cylinder is higher than the pressure in the bottle, and the liquid flows into the bottle by pressure difference. This method is often 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 is filled under the pressure in the bottle lower than the atmospheric pressure.
