Probe filler with electronical level filling system

• Electronical determination of the fill level via probe
• End of filling after probe signal
• Low-oxygen filling through several pre-evacuation steps with intermediary CO2 flushing
• Electropneumatic filling valve
• Infinitely variable filling speed with the Krones Proportional Flow Regulator (PFR)

Field of applications

• Suitable for wine and sparkling wine

Output

• Up to 60,000 containers per hour

HES = Height filling system, Electronic fill height measuring, Short tube

The lift cylinder presses the bottle on to the filling valve where it is pre-evacuated several times. With sparkling wines, the bottle is pressurised additionally. Afterwards, the valve opens and the product flows into the bottle via a swirl insert. The integrated PFR valve controls the filling speed infinitely adjustable enabling foamless filling. Once the bottle is completely filled, the filling valve closes via a probe signal. With sparkling wine, the container is additionally snifted via a separate channel.

Conductivity > 50 µS/cm
Viscosity < 10 mPa·s
Pulp ≤ 0.4 mm/proportionally < 10 % 
Fibres 1 x 5 mm/proportionally < 5 %

Foamless filling

• Use of swirl inserts at the filling valve outlet
• Use of PFR valves

Maximum filling accuracy

• Krones probe technology 

Perfect harmony between the pneumatic components and the electronic components

• All processes 100 percent reproducible: no additional installations (e.g. pressure transducer with corresponding electronics) required

Best technological values

• Several pre-evacuations 
• Optimal interconnected CO2 flushing

High filling stability

• Separation of the pressurisation channel and the snifting channel 
• Absolutely dry pressurisation without any aerosol carry-over

Precision and long service life

• Use of special pneumatic components with a significantly higher life cycle than the one of conventional switching valves

Hygienic design

• No installed parts in the tubular ring bowl 
• Vacuum pump integrated in the CIP circuit
• Height-adjustable splinter washout system
• Oil-free lift cylinders
• Self-draining surfaces
• Clean pneumatic components hosing and electrical wiring
