Bottle Liquid Filling Machine Working Principle

Liquid fillers are divided into different categories based on the working principle. These categories are Ordinary filling machines, Pressure filling machines, and Vacuum filling machines.

  • Ordinary filling machine

In an ordinary liquid filling machine, the liquid is filled owing to its weight. So they work by gravity, where you can fill the liquid in the particular bottle. It is obvious to take care of special requirements such as maintaining the fluids’ viscosity and gas bearing. Examples of vacuum filling machines are milk bottles and grapevines. 

  •  Vacuum filling machine

In vacuum filling machines, the pressure must be higher than the pressure of the bottles. The reason is that the liquids which are high in viscosity, such as syrup and oil, require vacuum filtration. 

So in pressure liquid filling machines, there must be a higher pressure than the atmospheric pressure as it is functional. Pressure filters are further categorized into two types such as equal air pressure filling and high-pressure filling.

In equal air pressure filling, the liquid reservoir pressure must be equal to that of the bottle. In high-pressure filling, there must be a pressure difference between the liquid reservoir and the bottle.
