Introduction to the working principle of the liquid packaging machine
According to the filling principle, the liquid filling machine can be divided into atmospheric filling machine, pressure filling machine and vacuum filling machine ; Atmospheric filling machine is filled by liquid weight under atmospheric pressure. This type of filling machine is divided into two types: timing filling and constant volume filling. They 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, and it can also be divided into two types: one is the pressure in the liquid storage tank and the pressure in the bottle Equal, filling by the liquid's own weight into the bottle is called equal pressure 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 the pressure difference. This is often used in high-speed production lines. method. The pressure filling machine is suitable for filling gas-containing liquids, such as beer, soda, champagne, etc.
Vacuum filling machine is to fill the bottle under the pressure lower than atmospheric pressure; liquid packaging machine is packaging equipment for packaging liquid products, such as beverage filling machine, Dairy filling machines, viscous liquid food packaging machines, liquid cleaning products and personal care products packaging machines, etc. all belong to the category of liquid packaging machines.
Due to the rich variety of liquid products, there are also many types and forms of liquid product packaging machines. Among them, liquid packaging machines for packaging liquid food have higher technical requirements. Sterility and hygiene are the basic requirements of liquid food packaging machines.
Use of liquid packaging machine
This package is suitable for soy sauce, vinegar, juice, milk and other liquids. It adopts 0.08mm polyethylene film. Its forming, bag making, quantitative filling, ink printing, sealing and cutting are all automatic. Disinfection meets the requirements of food hygiene.
