Introducing the 120° Pressure Arc Bending Screen tailored for the Starch Industry
The Pressure Arc Screen, synonymous with innovation, is alternatively known as the Pressure Arc Sieve Bend Screen or DSM Sieve Bend Screen. Designed as a high-performance screening solution, it boasts extensive applications, particularly in starch processing for multi-stage counter-current rinsing operations. Within the starch production process, it excels in efficiently separating starch from both germ and fiber, making it a crucial component in optimizing starch production.
Ingeniously crafted, the Pressure Arc Screen stands as a static yet highly efficient screening apparatus. Masterfully engineered to separate and grade wet materials under pressure, its surface benefits from advanced processing techniques, achieving an impeccably smooth, polished finish. The screen wire, renowned for its acute sharpness and exceptional wear resistance, ensures that as the starch milk, propelled by pressure, flows seamlessly across the screen surface, the process remains consistently steady, devoid of fluctuations or splashes.

Working Principle of Pressure Arc Screen - Sieve Bend Screen
The dynamic journey of the starch emulsion begins as it is precisely propelled from the nozzle onto the screen surface, meticulously orchestrated at an optimal pressure and speed. The emulsion glides along the tangent of the arc screen, spreading swiftly and uniformly, enveloping the screen surface before gracefully seeping through. Its path flows perpendicular to the screen slits, ensuring flawless
directional flow. As it journeys, the emulsion is influenced by the synergistic forces of centrifuge, impact, gravity, and the incisivescreen wire wedge, which deftly slices through the starch emulsion,
acting like a sleek, sharpened blade. Upon contact, the emulsion engages with this keen edge, transforming into a fine liquid layer. This layer, along with diminutive particles, seamlessly navigates through the narrow slots, becoming part of the undersize flow. Concomitantly, some liquid and larger particles traverse the screen,
emerging as oversize, ultimately flowing out through the overflow port, completing the emulsion's elegantly orchestrated passage.
- Experience superior efficiency in impurity separation. Our robust pressure arc screen is expertly designed to operate under high pressure, effectively removing fine particles and impurities from starch slurry. This ensures your final product is pristinely clean and completely devoid of contaminants.
- Exceptional screening efficiency. The ingeniously curved shape of our screen surface guarantees a uniform flow of starch slurry across the screen, thereby maximizing screening efficiency and significantly reducing the risk of blockages or clogging.
- Ingenious self-cleaning technology. Our pressure arc screen incorporates a state-of-the-art self-cleaning system. Trapped particles and impurities are effortlessly flushed away from the screen surface by an efficient backwash or flushing system, allowing for continuous operation without the hassle of manual cleaning.
- Built to last with unmatched durability. Crafted from premium-grade stainless steel, our pressure arc screen boasts exceptional resistance to corrosion and wear. This ensures a long-lasting lifespan with minimal maintenance, making it a reliable choice for years to come.
- Tailored customization options. Our pressure arc screen offers versatile customization to meet the distinct requirements of various starch processing applications. With an array of screen sizes, slot dimensions, and pressure ratings, it is designed to precisely suit different operating conditions.
