Introducing the 120° Pressure Arc Bending Screen: The Starch Industry's Unrivaled Solution
Experience the cutting-edge innovation of our Pressure Arc Screen, also known as the DSM Sieve Bend Screen. This state-of-the-art screening equipment is designed for versatile applications, particularly in starch processing. Ideal for multi-stage counter-current rinsing, it streamlines the starch production process by expertly separating starch from germ and fiber, making it an indispensable part of starch manufacturing.
The Pressure Arc Screen epitomizes static efficiency in screening technology. Uniquely engineered to separate and grade wet materials through pressure, its meticulously processed and highly polished screening surface is unparalleled in smoothness and uniformity. With screen wires boasting razor-sharp edges and exceptional wear resistance, this equipment ensures seamless flow of starch milk at specific pressures without disturbances, guaranteeing optimal performance without fluctuations or splashes.

Working Principle of Pressure Arc Screen Sieve Bend Screen
The starch emulsion is sprayed from the nozzle onto the screen surface with precision at a specified pressure and speed, ensuring optimal coverage. It is delivered along the arc's tangent, maximizing efficiency, as it swiftly spreads across the screen. This even distribution allows for rapid flow through the screen, enhancing processing efficiency. The flow direction is precisely perpendicular to the screen slit, ensuring
the starch emulsion is effectively influenced by centrifugal forces, impact forces, gravity, and the cutting action of the intricately designed screenwires. These forces work in unison to refine the emulsion on the concave
arc screen surface. The wedge wire acts as a precision instrument, similar to a sharp blade, efficiently targeting and impacting the starch emulsion. This action scrapes the starch into a fine liquid layer, allowing it and minute particles to seamlessly pass through the narrowly engineered screen slits, forming the high-quality undersize. Meanwhile,
a portion of the liquid layer and larger particles are gracefully guided over the surface, becoming the oversize, which exits via the overflow port.
- Enjoy efficient separation of impurities with cutting-edge technology. Our pressure arc screen is ingeniously designed to thrive under high-pressure environments, adeptly removing fine particles and impurities from the starch slurry. This ensures a pristine final product, devoid of any contaminants.
- Elevate your operations with high screening efficiency. The uniquely designed curved shape of our screen surface ensures that starch slurry flows uniformly, optimizing screening efficiency and significantly reducing any risk of blockages or clogs.
- Experience the ease of self-cleaning technology. Intelligently engineered, the pressure arc screen is self-cleaning. Trapped particles and impurities are effortlessly removed from the screen surface through a sophisticated backwash or flushing system, guaranteeing uninterrupted operation without the need for manual intervention.
- Built to last with durability and longevity. Crafted from premium high-quality stainless steel, our pressure arc screen is resistant to corrosion and wear. This ensures many years of reliable service with minimal maintenance, making it a cost-effective choice.
- Tailored to your needs with customizable solutions. Our pressure arc screen is fully customizable to meet the diverse demands of various starch processing applications. Choose from an array of screen sizes, slot sizes, and pressure ratings to suit any operating condition seamlessly.
