Leybold BBVS (Beer Bottling Vacuum System)

Leybold has developed a sustainable vacuum system which, depending on bottle size, can support filling lines with outputs of up to 60,000 bottles per hour.

The BBVS (Beer Bottling Vacuum System) comes as an all-in-one turnkey solution designed to replace the old liquid ring pump technology. It includes a separator tank with an automatic-operated draining vessel to stop foam and liquid carried over from the filler via the gas flow.

The DRYVAC dry screw vacuum pump provides deep constant vacuum levels, while an electrical cabinet with PLC controls the entire system.

The equipment can be interfaced with the filler via digital I/Os or a fieldbus for remote control and can also operate as a standalone system via push-buttons.

The water-cooled DRYVAC models, the DV 650 FP-r and DV 800 FP-r, are part of the complete solution. At ultimate pressures, the DV 650 FP-r generates a noise level of just 67 dB(A), while the DV 800 FP-r generates 70 dB(A). These low levels allow the pumps to be installed in the immediate vicinity of the filling systems. It’s also worth noting that DRYVAC models generate and emit very little heat. The comparatively low internal temperature profile of the screw vacuum pump also prevents the formation of caramel layers that can potentially appear when sugars, carried over with residual beer droplets, are exposed to high temperatures.

A CIP (cleaning in place) spray ball, located inside the top area of the stainless steel separator, allows for the cleaning of all surfaces that come into contact with beer (specifically inside the separator and the draining vessel). Cleaning can be done without switching the system off or dismantling it.

The DRYVAC FP features a stainless steel silencer and is covered by a corrosion-protective coating, making it 100% suitable for washdown environments.
