The invention relates to a device comprising a substantially cylindrical housing (2) in a mixing region (7). Said housing comprises at least one outlet channel (15) having an outlet opening (6) in the mixing region (7) and at least one rotationally supported mixing shaft (4) having at least one discharge element (3) having an effective surface. The discharge element (3) can be guided past the outlet opening (6) when used properly, wherein a projection of the effective surface (8) parallel to the outlet channel axis covers the smallest outlet channel cross section of the outlet opening (6) at least once per revolution of the discharge element (3) by at least 45%, preferably by at least 50%, particularly preferably by at least 55%, and most particularly preferably by at least 60%. The projection of the effective surface (8) parallel to the outlet channel axis preferably covers the smallest outlet channel cross section of the outlet opening (6) at least once per revolution of same by at least 50%, particularly preferably by at least 55%, and most particularly preferably by at least 60%.
