A liquid filling machine is a type of machine essential in the industry that is equipped with an enormous level of precision. It depends on it that the containers are filled with the necessary quantities of liquid fulfilling the guidelines imposed by each company.

Functions of the liquid filling machine

For the work of the liquid filling machine to be carried out in a successful way, it has to fulfill a series of results:

¡¤ The liquid introduced must be exact, neither a greater nor a smaller volume.

¡¤ The process must be fast.

¡¤ You have to guarantee hygiene at all times.

¡¤ The accuracy will ensure that maintenance is sporadic.

¡¤ The whole process must be sterilized.


Types of filling machines

There are some aspects in which all the liquid filling machines coincide, as is the case of being formed by an accumulator system tank or a circulation system through which the different bottles or containers pass. What changes mainly between the different types are; the nozzles that are used for filling.

Mainly there are two large groups:

¡¤ Volumetric fillers

¡¤ Constant level fillers


The volumetric ones are the simplest and most direct, working on filling the bottles with a certain volume of liquid. They are divided into three groups:

¡¤ Beaker filling machines

¡¤ Fixed piston fillers

¡¤ Commanded piston filling machines.



Each one of the types makes use of a form of particular filling derived from its name, being recommendable depending on the process that is going away to realize. For example; the beverage filling machine, and the commonly used water filling machine. However, there is a problem that although the filling process is accurate, the difference between the bottles leads to the filling level being different from each other.


In the case of filling machines of constant level, the leveling of the liquids is more precise and the problem that the volumetric ones have is avoided. There are also three types: siphoning, isobarometric and differential pressure. The filling system is altered depending on the type, but in all three cases the precision that represents this type of liquid packing machine is guaranteed.

Beverage filling machine: How it works

A good example to understand the work of the bottling of liquids is through the filling of the wine using the beverage filling machine, which passes from the cellars to the bottles in an automated and simple way. There are a series of tasks that must be carefully followed at all times:

Avoid the dangers that can exist of contamination through the environment, such as dust or microorganisms. Avoid bad stowage and that toxic products can influence the filling system.

Take preventive measures making sure that the machine and the whole environment have the best hygiene measures.

The manipulation by the operators must always be hygienic and with controls.

Surveillance of the filling processes to ensure that no problems occur.

Avoid overlooking mistakes. You can never allow a badly filled bottle to go through the distribution phase.

Prepare maintenance records that support the work done.


Bottle filling level analysis system

To ensure that the filling processes comply with all the guidelines in any type of liquid it is advisable to make use of a deep and modern analysis system.

¡¤ The filling is correct.

¡¤ No incident has occurred (with the possibility of adjusting some alarms and previous warnings).

¡¤ Any anomaly has been identified.

¡¤ The headspace, the space between the filling and the cork, is the right one.
