摘要: A device for filtering a fermented liquid comprises at least one filtration chamber with a feed (21,31) and a discharge (22,32) for a main flow of the liquid for filtering in a first part (51) of the chamber and with a discharge (23,33) for a permeate recovered from the liquid in a second part (52) of the chamber. Both parts of the filtration chamber are herein mutually separated by a filter (10). According to the invention the filter (10) comprises a filter layer (2) with pores of a precisely determined size which are formed making use of photo-lithographic techniques. An exceptionally steep pore pitch distribution in an exceptionally flat filter surface can thus be obtained, which manifests itself in an extremely reliable filtration result associated with a high flux and operational reliability.
