The screw is fabricated to have a reinforced construction by way of a rigid main stem portion disposed radially inwards of a rigid sieve-forming surface portion and reinforcing ribs disposed between these portions. Screw threads of the screw are secured directly to the sieve-forming surface portion while a drainage duct for draining fluid from the latter portion is formed between this portion and the main stem portion.
