Do you know the working principle of common filling machines? Next, I will give you a brief introduction.

filling machine, as the name suggests, is a mechanical equipment that packs various forms of items such as liquids, gases, pastes, and powders. Belongs to packaging equipment. According to different filling objects, filling machines can be divided into: liquid filling machine, gas filling machine, aerosol filling machine, paste filling machine, powder filling machine, etc. According to the degree of automation, filling machine Often divided into: aluminum can filling machine automatic filling machine, powder filling machine, etc. Machine tools, semi-automatic filling machines, automatic filling machines, etc., with the continuous increase of domestic labor costs, and with the development of automatic filling machines, automation and intelligence will receive more and more attention.

According to different filling objects, the filling principle and filling method are very different.

According to different filling pressures, liquid filling machines can be divided into atmospheric liquid filling machines, vacuum liquid filling machines and pressure liquid filling machines.

Atmospheric pressure liquid filling machine is based on the weight of liquid self-flow filling, and has greater requirements for liquid viscosity, gas, etc. It can be divided into conventional filling and volume filling according to the filling method. Common fillings are wine and milk.

Vacuum filling machine fills bottles under pressure below atmospheric pressure. The filling machine has simple structure and high efficiency. Generally used in high viscosity liquids, such as oil, syrup, fruit wine, etc.

Pressure filling machine refers to filling under pressure higher than normal. It can also be divided into two types: one is the pressure in the tank equal to the pressure in the bottle, when the liquid's own weight flows into the bottle, it is called isostatic filling; the other is the pressure in the tank is higher than the pressure in the bottle, it is called isobaric Filling. The liquid flows into the bottle through the pressure difference, which is called high pressure. Pressure filling is a commonly used filling method in high-speed liquid filling production lines. Pressure filling machines are usually used for filling gas liquids, such as beer, soda, champagne, etc.
