Mashwing
the banke agitator for perfect mashing
Homogeneity and rapid distribution of heat throughout the mash are the demands brewers place upon an agitator.
The distinctive banke agitator blades, formerly known as GentleMix, guarantee maximum heat transfer and uniform temperature distribution as well as intensive mixing of the mash due to their unique geometry designed to optimize flow. This takes place at low speeds and thus alleviates shearing forces on the husks.
Key facts
- intensive mixing with effective heat transfer
- reduced energy consumption – up to 60 % less
- gentle treatment of the husks means shorter lautering times
- flow profiles are optimized through computational fluid dynamics (CFD
- higher final attenuation
Optimal agitation during mashing
The agitator blade geometry guarantees consistent flow across the bottom heating zone of the mash vessel and throughout the entire cross-section of the mash.
High flow rates, close to the wall of the vessel, creates conditions conducive for maximum heat transfer. Induced vortex flow generates optimal circulation throughout the mash and maximizes homogeneity.
As a result, enzymatic degradation processes are more effective, guaranteeing higher yields.
Gentle circulation at low speeds
The agitator provides optimal mash circulation – even at low rotational speeds, so that the shearing forces acting on the mash are significantly reduced. The gentle stirring of the husks in the mash means that lautering takes less time.
Optional: additional baffle plates for optimizing flow in thick mashes
Baffle plates installed in the vessel to optimize flow significantly improve mixing throughout the entire cross-section of the mash. These baffle plates ensure that the heat introduced across heat transfer surfaces or through a mash liquor addition diffuses quickly and evenly through the entire volume of the mash.
Flow - optimized agitator design
We have put the finishing touches on our agitator blades, which were developed through rigorous empirical testing with the latest in computational fluid dynamics (CFD) and were designed to create optimal flow conditions and mixing.

The CFD simulation has revealed that excellent mixing results have been achieved throughout the entire volume of the mash in conjunction with extremely low shearing forces.
