120° Pressure Arc Bending Screen for Starch Industry
Discover the unparalleled versatility of the Pressure Arc Screen, often referred to as the DSM Sieve Bend Screen. This cutting-edge screening solution plays a pivotal role in starch processing, thanks to its sophisticated multi-stage counter-current rinse capability. Essential in the starch production chain, it efficiently separates valuable starch from germ and fiber, ensuring a seamless and refined production experience.
Experience the next level of screening precision with our static and highly efficient Pressure Arc Screen. Designed to separate and grade wet materials expertly through pressure, this innovative equipment boasts a meticulously processed screen surface, ensuring a mirror-like finish that's both smooth and uniform. With wires featuring sharp edges and exceptional wear resistance, it guarantees performance without fluctuations or splashing, even as highly pressurized starch milk swiftly traverses its surface.

Working Principle of Pressure Arc Screen Sieve Bend Screen
In our innovative process, the starch emulsion is artfully sprayed from a precision-engineered nozzle onto the delicately designed screen surface, ensuring the perfect balance of pressure and spray speed. This allows the starch emulsion to be applied with finesse along the tangent direction of the elegantly curved arc screen surface, where it effortlessly spreads and uniformly envelops the screen surface, swiftly flowing through the expertly crafted screen surface. The flow of the starch emulsion is precisely aligned at right angles to the screen slits,
where the emulsion experiences a symphony of forces: centrifugal, impact, gravity, and the precise cutting force of the screen wire's sharp-edgedwedge working its magic on the starch emulsion along the concave arc screen.
The wedge-shaped screen wire serves as an effective, sharp blade. As the starch emulsion collides with this finely honed edge, it is expertly transformed into a thin liquid layer. This liquid layer, along with the fine particles, effortlessly passes through the narrow, carefully designed screen slits, forming the undersize flow below. Meanwhile, part of the liquid layer and coarser particles
continue their journey across the screen surface, becoming the oversize, and gracefully exit through the overflow port.
- Efficient separation of impurities. Our pressure arc screen is meticulously engineered to thrive under high-pressure environments, ensuring the effective removal of even the finest particles and impurities from starch slurry. This guarantees that your end product is impeccably pure and devoid of any contaminants.
- High screening efficiency. The innovative curved design of the screen surface ensures a uniform flow of starch slurry across the screen. This maximizes screening efficiency while significantly reducing the potential for blockages or clogs, ensuring smooth operation.
- Self-cleaning. Our pressure arc screen boasts a self-cleaning mechanism, where trapped particles and impurities are effortlessly cleared from the screen surface through a robust backwash or flushing system. This feature ensures continuous operation without the hassle of manual cleaning interventions.
- Durable and long-lasting. Crafted from top-tier stainless steel, our pressure arc screen is designed to withstand corrosion and wear. This exceptional durability ensures the screen remains a reliable component for many years with minimal maintenance requirements.
- Customizable. Tailored to meet the nuanced demands of various starch processing applications, our pressure arc screen can be customized. We offer a variety of screen sizes, slot dimensions, and pressure ratings to perfectly align with diverse operating conditions.
