Abstract
A block former (1) for the production of blocks of cheese (19) includes an upright drainage column (2) having a feed opening (3) for curd particles (4) at an upper end (5) of the drainage column (2). The drainage column (2) includes an inner wall (6) having an interior surface (7) against which a pillar of curd (8) formed of the curd particles (4) slides as the pillar of curd (8) moves downwardly through the drainage column (2). The upright drainage column (2) is divided into an upper part (9) and a lower part (10). The interior surface (7) at the upper part (9) has a first finish and the interior surface (7) at the lower part (10) has a second finish that provides higher friction with the pillar of curd (8) relative to the first finish.
