Volumetric filler

• Electronic filling system with inductive flow meter or mass flow meter
• Pressing-on process without curves
• Infinitely adjustable flow speed
• End of filling after signal from flow meter
• Product feed from top via adjacent product tank

Field of applications

• Filling of both carbonated and non-carbonated water into PET containers, with and without conductivity

Output

• Up to 86,000 bottles per hour

VFS = Volumetric filling system, Flow meter, Short tube

The filling valve moves electropneumatically onto the PET container without a stroke control cam. Afterwards, the container is pressurised. Once the same pressure is in the product tank and the PET container, the filling valve will be opened and the filling process starts. The liquid is gently fed via a swirl insert into the bottle. With the PFR valve, the speeds are infinitely adjustable, guaranteeing optimum flow behaviour. A flow meter monitors the fed liquid quantity. Once the exact filling volume has been reached, the flow meter provides a signal and the valve closes electropneumatically. After a settling phase, the pressure in the head space of the PET container is reduced via a snifting valve and the filled product exits the machine.

Conductivity: > 20 μS/cm
Viscosity: < 10 mPa·s
Pulp: ≤ 0.4 mm/proportionally < 10 % 
Fibres: 1 x 5 mm/proportionally < 5 %

Maximised flexibility

Non-carbonated and carbonated products can be filled on one system.

Enhanced product quality

The new PFR valve enables optimum adjustment of the filling speed to suit the particular product properties. Products which tend to foam excessively can also be processed. 

Increased output

The filler operates without lifting cam, which increases the filling angle: This in turn increases the output, and that for the same line size. Filling water with a PFR valve, for instance, will increase the annual output by up to 25 per cent, that is 72 million bottles (based on 0.5 litre bottles and a pitch diameter of 4,320 mm).

Reduced product loss

Thanks to the adjacent product tank, the product can be fed to the filler from above, reducing product loss to a minimum (optional: Modulfill VFS-M with integrated mixer and raised carbonation tank).

Improved cleaning

The CIP cups automatically swing into place using a magnet. This contact-free process without pneumatic components optimises the hygienic conditions and enables the installation of more filling valves on a pitch diameter.

Saved energy and raw materials

The PFR valve operates electronically. This saves 30 percent of compressed air when compared to electropneumatic filling.
