working principle of liquid filling machine
Liquid filling machines can be divided into atmospheric pressure filling machines, pressure filling machines and vacuum filling machines according to the filling principle; the atmospheric pressure filling machines are 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 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.
Vacuum filling machine is filling under the pressure in the bottle below atmospheric pressure; liquid packaging machine is packaging equipment for packaging liquid products, such as beverage filling machine, dairy filling machine, viscous liquid food packaging machine, liquid cleaning Supplies and personal care 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, the liquid packaging machines used to package liquid food have higher technical requirements, and aseptic and hygienic are the basic requirements of liquid food packaging machines.
The purpose of the liquid filling machine is suitable for soy sauce, vinegar, juice, milk and other liquids. It adopts 0.08mm polyethylene film, and its forming, bag making, quantitative filling, ink printing, sealing and cutting are all automatic. Ultraviolet disinfection is carried out to meet the requirements of food hygiene.
