摘要： The invention relates to a crossflow-filtration method for beverages, in particular beer, which comprises the following steps: a) the feed liquid is introduced into a filter module by means of a tangential flow through a filter membrane (6) in a first direction, whereby the filtrate flow on the filtrate side (19) of the filter module is maintained within predetermined threshold values; b) the entry pressure is reduced and the filter is backflushed by surges of filtrate initiated by a reversal of the flow direction transversally to the membrane; c) the feed liquid is optionally introduced in an inverse flow direction to that of step a) and the concentrate is evacuated on the non-filtrate (7) side of the module; d) the entry pressure is reduced and the filter is backflushed by surges of filtrate initiated by a reversal of the flow direction transversally to the membrane; e) steps a) to d) are repeated until the filtrate flow lies below the lower predetermined threshold value; f) to k) the filter is emptied by applying pressure, backflushed, rinsed and l) steps are resumed.
