Abstract:
1. Mashing process, wherein mash is filtered and wort is obtained, characterized in that the mash is fed to a filter material having a retentate side, a filtrate side, and a retention rate of below 2 μm of a dynamic cross-flow filtration system, namely a means for filtration, where the material to be filtered is moved in a volume segment between a filter surface and a further surface, with at least an essential component of the relative velocity between the material to be filtered and the filter surface, running along the filter area perpendicular to the normal of the filter area (cross-component), said cross-component being essentially produced by movement of surfaces within the cross-flow filtration system itself relative to the material to be filtered, wort is withdrawn from the filtrate side of the filter material and thickened remainder is withdrawn from the retentate side of the filter material.
