Liquid packaging machines, that is, packaging equipment for packaging liquid products, such as beverage filling machines, dairy product filling machines, viscous liquid food packaging machines, liquid cleaning products and personal care packaging machines, are all liquid packaging machines.
It is suitable for soy sauce, vinegar, juice, milk and other liquids. It uses 0.08mm polyethylene film. Its forming, bag making, quantitative filling, ink printing, sealing and cutting processes are automatically performed. The film is sterilized by UV before packaging. Food hygiene requirements.
How it works
Atmospheric pressure filling machine is filled with liquid weight under atmospheric pressure. This type of filling machine is divided into two types: timing filling and constant filling. It is only suitable for filling low-viscosity gas-free liquids such as milk and wine.
The pressure filling machine fills 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 bottle is filled by the weight of the liquid, called filling. Isobaric filling; on the other hand, the pressure in the liquid storage tank is higher than the pressure in the bottle, and the liquid flows into the bottle through the pressure difference. This method is used in the high-speed production line. The pressure filling machine is suitable for liquid filling, such as beer, soda, champagne, etc.
The vacuum filler is filled at a pressure below atmospheric pressure in the bottle.
