120° Pressure Arc Bending Screen for Starch Industry
The pressure arc screen, also known as the pressure arc sieve bend screen or DSM Sieve Bend Screen, stands as a cutting-edge screening solution with versatile applications. It plays a vital role in the starch processing industry, particularly for multi-stage counter-current rinsing. During starch production, this indispensable piece of equipment efficiently separates starch from both germ and fiber, marking a critical step in the starch production process.
The pressure arc screen is a state-of-the-art, static, and highly efficient screening equipment, designed to separate and grade wet materials using pressure. Engineered with precision, its screen surface is crafted through special processing methods, resulting in a highly polished finish. The smooth and uniform screen surface features wires with sharp edges, offering exceptional wear resistance. When starch milk, propelled by pressure, flows rapidly across this surface, the process remains stable with no fluctuations or splashes, ensuring seamless operation.

Working Principle of Pressure Arc Screen Sieve Bend Screen
The starch emulsion is expertly sprayed from the nozzle onto the screen surface, utilizing precise pressure and optimal spray speed. This targeted approach ensures the starch emulsion is efficiently directed to the screen surface along the tangent direction of the arc screen. It then rapidly spreads, uniformly covering the screen surface, ensuring quick and smooth passage through the screen surface. The flow direction of the starch emulsion is maintained at right angles to the screen slit,
subjecting it to an intricate blend of centrifugal force, impact force, gravity, and the precise cutting force of the screen wire's sharp edge, all acting on thestarch emulsion on the concave arc screen surface.
The wedge-shaped screen wire acts like a deftly sharp knife. As the starch emulsion makes contact, it impacts the keen blade of the screen wire, transforming the starch into a delicate liquid layer. This liquid layer, along with fine particles, seamlessly passes through the narrow and expertly designed small screen slits, entering the bottom flow to form the desirable undersize. Meanwhile, part of the liquid layer,
accompanied by coarser particles, flows across the screen surface, becoming the oversize and is efficiently directed out through the overflow port.
- Experience supreme efficiency in impurity separation. Our pressure arc screen is ingeniously crafted to withstand high pressures, effortlessly removing fine particles and impurities from starch slurry. This ensures a final product that is impeccably clean and entirely free from any contaminants.
- Achieve unparalleled high screening efficiency. The expertly curved design of the screen surface guarantees a uniform flow of starch slurry, enhancing screening efficiency remarkably while reducing the risk of blockages or clogs to an absolute minimum.
- Self-cleaning: A Revolution in Maintenance Ingeniously engineered for self-cleaning, the pressure arc screen eliminates trapped particles and impurities through an effective backwash or flushing system. This innovation ensures uninterrupted operation and obviates the need for manual cleaning.
- Built to Last: Durable and Long-Lasting Constructed from premium-grade stainless steel, our pressure arc screen boasts exceptional resistance to corrosion and wear, promising durability and longevity with minimal maintenance over the years.
- Tailored to Perfection: Customizable Solutions Our pressure arc screen offers customizable options to perfectly align with various starch processing demands. Available in diverse screen sizes, slot sizes, and pressure ratings, we cater to distinct operational conditions seamlessly.
