The Sieve Bend Screen is commonly used in food processing and corn wet milling for dewatering. Sieve bend screens help to achieve the best quality product at a low operating cost. They achieve better separation and better dewatering than other standard screening methods.

Basic Principles

The vee type profile wires enable the screen to effectively separate fibres to a fine degree. The process flow is introduced to the sieve bend screen via high-pressure nozzles, which distributes the flow tangentially over the entire width of the screen. The sieve bend screen will then proceed to a layers of slurry with the accompanying fine particles, ultimately the filtrate media. This action results from the sharp upper edge on the profile wires.

Benefits

Features of the sieve bend screen include:

Reduced equipment and installation costs

Low maintenance costs

Better flow rate and finer fibre removal

Wide range of applications

Longer lifetime

Slot sizes range from 50 μm to 10 mm

Typically made with 304, 316, 316L stainless steel

Application

Corn dewatering (gravity screens, 54” long screens, 3 mm slot openings, corn dewatering)

Germ washing system (gravity screens, 31” long screens, 1mm screen spacing, germ washing screens)

Second grind dewatering, corn slurry (gravity screens, 54” long screen surfaces, 1.5 mm slot openings, second grind dewatering)

Fiber dewatering (120 degree pressure screens)
