ABSTRACT:
The sieve plate herein is formed of plate or sheet material into which relatively wide grooves, having a flat bottom 4 mm wide, are formed on one side to within 1 mm of the opposite side. Through this remaining membrane wall openings are formed having a width of about 1 mm. The small openings may either be spaced circular perforations or slots. The slots may be in zig-zag formation. Zig-zag formations are preferred because it maximizes the filtering area.
