Water filling machine work according to the gravity filling principle. These machines need a different number of operators depending on the degree of automation (semi-automatic or fully automatic).
We explained the working principle of automatic water filling machines, which are quite common and preferred for you. Thanks to this article, you will learn the basic information you need to know about a water filling machine.
First, let's explain the general working principle of liquid filling line. Liquid products are filled in bottles with some exceptions. Cardboard boxes, pouches, and cans are also products for liquid filling except for bottles. Since it is the most preferred bottle in water filling, we will give you extensive information on bottle liquid filling.
Water Filling Machine Working Principle
Liquid bottle filling machines perform 3 main operations:
Bottles are placed on the conveyor and taken to the washing unit. Their inside and outside are washed with distilled water and dried.
Bottles come to the filling unit by the conveyor and are filled into the bottle by different methods according to the filling liquid viscosity.
Filled bottles are sealed in this section until they are opened by the end user. The sealing unit should be attached to the liquid filling machine for the sealing process, which is important for safety and hygiene.
Now we will examine the gravity filling system, which is the working method of water filling machines.
Gravity Filling-Water Filling Machine
Based on the working principle, liquid fillers are divided into ordinary, pressure and vacuum filling machines. The ordinary liquid fillers work by gravity, in which the liquid is filled due to its weight into particular bottles. However, it is necessary to meet special requirements to maintain the viscosity and gas bearing of the fluids. Notable examples of this are milk bottles and grape wine etc.
The vacuum fillers require the atmospheric pressure to be greater than the pressure of the bottles. Liquids such as syrup, oil, and wine, etc. have high viscosity and require this type of filling, which is very efficient and employs a very simple structure.
The pressure liquid fillers need to have greater pressure than the atmospheric pressure to be functional. This type of filling is further divided into “equal air pressure filling” and “high-pressure filling.” In “equal air pressure filling,” the pressure of the liquid reservoir gets equal to the pressure of the bottle, and so the liquid proceeds into the bottles by their weights. The high-pressure filling, on the other hand, works by the pressure difference between the liquid reservoir and the bottles.
