Working Principle of filling machine

Filling machine, as the name implies, is a mechanical equipment that encapsulates various forms of objects such as liquid, gas, paste, powder, etc. It is a kind of packaging equipment. According to the different filling objects, the filling machine 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: automatic filling machine, semi-automatic filling machine, full-automatic filling machine, etc; With the gradual increase of domestic labor costs, the development of automatic filling machine equipment will pay more attention to full automation and intelligence. According to the different filling objects, the filling principle and filling mode of the filling machine are also very different. According to the different filling pressures, the liquid filling machine is divided into: normal pressure liquid filling machine, vacuum liquid filling machine and pressure liquid filling machine. The normal pressure liquid filling machine implements self-flow filling according to the weight of the liquid itself. This kind of filling machine has great requirements on the viscosity and gas content of the liquid. According to the filling mode, it can be divided into regular filling and constant volume filling, common filling objects include wine and milk. The vacuum filling machine is filled at a pressure lower than atmospheric pressure in the bottle. This kind of filling machine is simple in structure and high in efficiency, and is generally used for liquids with high viscosity, such as oils, syrup, fruit wine and so on. The pressure filling machine refers to filling under the condition of higher than normal pressure, which can also be divided into two types: one is that the pressure in the liquid storage cylinder is equal to the pressure in the bottle, and the filling is carried out by the liquid flowing into the bottle by its own weight, called equal pressure filling; The other is that the pressure in the liquid storage tank is higher than that in the bottle, and the liquid flows into the bottle by the pressure difference. This method is called high-pressure filling, which is usually used in high-speed liquid filling production lines. Pressure filling machine is usually used for filling liquid containing gas, such as beer, soda, champagne, etc.
