The working principle of common filling machines

  Filling machine, as the name implies, is a mechanical equipment that packs various forms of items such as liquids, gases, pastes, powders, etc., and belongs to packaging equipment. According to the 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 machines are often divided into: semi-automatic filling machines, automatic filling machines, etc. With the continuous increase of labor costs, with the development of automatic filling machines, automation and intelligence will be more and more affected. 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.

  The atmospheric liquid filling machine is based on the weight of the liquid self-flow filling, and has greater requirements for liquid viscosity and gas. According to the filling method, it can be divided into conventional filling and volume filling. Common fillings are wine and milk.

  The vacuum filling machine fills bottles at a pressure lower than atmospheric pressure. The filling machine has a simple structure and high efficiency. Generally used for high-viscosity liquids, such as oil, syrup, fruit wine, etc.

  Pressure filling machine refers to filling under the condition of higher than normal pressure. It can also be divided into two types: one is the pressure in the tank is 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 gaseous liquids, such as beer, soda, champagne, etc.
