Two distinct filling technologies are available for semi-automatic and fully automatic filling machines: volumetric and vacuum-level filling.

Manually operated filling machines tend only to fill volumetrically.

Volumetric filling machines

 

Manual liquid filling machines use a piston within a cylinder to force liquid into the container.

These normally have a pneumatically powered pump mechanism, set to fill containers with the required volume of liquid, fed from either a floor-standing container or a machine-mounted hopper.

Containers are positioned below the filling nozzles and a foot pedal switch to start the filling process.

Volumes between 5ml and 25-litres can be handled by volumetric filling machines and up to 150 containers per minute can be filled, depending on the fill volume, liquid viscosity and level of machine automation.

Vacuum level filling machines

 

Vacuum level semi-automatic filling machines use the rim at the top of the container to form an airtight seal around the filling nozzle.

This airtight seal creates a vacuum within the bottle which draws free-flowing liquids from a supply tank into the bottle, via specially designed nozzles. These nozzles have a small hole on the side which is connected to a small internal tube.

The height of this hole in relation to the top of the container during filling determines the level of liquid dispensed. The small hole in the nozzle scavenges excess liquid from the filling process and collects it in a receiver for reuse.

Vacuum level filling machines fill containers to the same height each time, rather than dispensing the same volume. This is particularly useful for glass bottles which will be side-by-side on display shelves in shops. Glass bottles vary in capacity quite a lot, yet vacuum-level filling ensures the level each bottle is filled to is the same, giving a consistent appearance from one bottle to the next. Vacuum level filling requires rigid containers which won’t collapse under a vacuum.

Vacuum-level machines have virtually no moving parts, making them incredibly reliable, and can fill up to 120 bottles per minute depending on the container type, number of filling heads and level of automation.

Bottles are simply positioned with their top in contact with a sealing ring around the nozzle. The container will start to fill as soon as an airtight seal is made and stop when the pre-determined fill height is reached.

When comparing different liquid filling machines and types, it’s important to consider several factors to ensure that you choose the machine that best meets your needs.

Here are some key factors to consider:

  1. Machine type: Different filling machine manufacturers offer different types of machines, such as vacuum level fillers, piston fillers, and volumetric fillers. Consider which type of machine is best suited for your product and production needs.
  2. Production capacity: The production capacity of the machine is another important factor to consider. Compare the output of each machine to ensure it meets your production requirements.
  3. Level of automation: Some filling machines are fully automatic, while others are semi-automatic or manual. Consider the level of automation required based on your production needs and budget.
  4. Machine customization: Some manufacturers offer customization options to tailor the machine to your specific needs. Consider whether customization is important to you.
  5. Machine features: Look for features such as ease of use, ease of maintenance, and the ability to fill different types of containers.
  6. Quality and reliability: Consider the reputation of the manufacturer and the quality of their machines. Look for reviews and testimonials from other customers to get an idea of the machine’s reliability and performance. Better still, if you are able to visit the manufacturer and see their machines in action.
  7. Price and value: Compare the prices of different machines and consider the value offered. Will the cheapest machine you find be built to a high enough standard to provide the level of accuracy and dependability you require?

By considering these factors and comparing different filling machine manufacturers, you can make an informed decision and choose a machine that best meets your needs and budget.
