Ziemann Holvrieka Launches BubbleBoil Wort Boiling System for Energy Efficiency in Breweries
Ziemann Holvrieka has launched the BubbleBoil wort boiling system, which reduces evaporation rates from 4% to 1.5%, resulting in significant energy savings for breweries. This system, compatible with existing external boilers and CIP processes, allows for approximately 30% energy savings while maintaining beer quality equivalent to traditional brewing methods. The technology has already been successfully implemented in a large brewery, meeting MEBAK quality parameters.

Ziemann Holvrieka introduced the BubbleBoil wort boiling system, designed to reduce evaporation rates from 4% to 1.5%, leading to significant energy savings. The system operates with an external boiler, where wort is heated above boiling point and reintroduced to the kettle through nozzles.
This process generates vapor bubbles for uniform mixing and removal of undesirable substances like dimethyl sulfide (DMS). A triangle test confirmed that beer produced with BubbleBoil is sensorially equivalent to conventionally brewed beer.
The system is easy to retrofit for breweries already using external boilers, allowing for approximately 30% energy savings without needing energy recovery systems. It is compatible with existing CIP processes and meets MEBAK quality parameters, having been successfully implemented in a large brewery.
