In the core screening process of starch processing, traditional separation equipment often encounters the following technical bottlenecks:
Starch separation processes demand extremely high requirements for screening precision and continuity. Our specialized curved wedge wire screen achieves breakthrough improvements in screening efficiency and service life through unique curved structure design and precision manufacturing processes.
Our Starch-Specialized Wedge Wire Screen features innovative curved structure design:
60-120 degree arc curvature, perfectly matching starch milk flow characteristics.
Material forms uniform thin layer on screen surface, achieving over 85% effective screening area utilization.
V-shaped wedge wire structure guides fiber impurities to discharge along the surface tangent Direction.
Screen slot width precisely controlled at 50-150 microns, meeting various starch fine separation requirements.
Slot uniformity tolerance controlled within ±5 microns, ensuring consistent product quality.
Special surface treatment allows smooth passage of starch granules while efficiently retaining proteins and fibers.
316L stainless steel wedge wires fully circumference-welded to high-strength support beams.
Curved structure naturally enhances rigidity, improving deformation resistance by 200%.
Withstands 0.4-0.6 MPa working pressure, adaptable to high-pressure feeding processes.
V-shaped opening design of wedge wires prevents fiber impurities from forming bridging blockages.
Curved surface promotes material self-cleaning, reducing manual cleaning frequency.
Supports online high-pressure water backflush systems, reducing maintenance time by 80%.
Increase starch extraction rate by 2-3 percentage points, reducing protein residue below 0.3%.
More uniform product particle size distribution, meeting high-end food processing requirements.
Better temperature control during screening, protecting starch’s natural characteristics.
Wedge wire screen service life reaches 3-5 times that of traditional screens.
Cleaning frequency reduced from 2-3 times daily to 1-2 times weekly.
Energy consumption reduced by 15-25%, with significant water-saving effects.
