120° Pressure Arc Bending Screen for Starch Industry
The pressure arc screen, often referred to as the pressure arc sieve bend screen or DSM Sieve Bend Screen, represents the pinnacle of advanced screening technology. This versatile piece of equipment is indispensable in the realm of starch processing, where it excels in multi-stage counter-current rinsing. Within the starch production process, it plays a pivotal role in the precise separation of starch from both germ and fiber, thereby making it an essential component in the production of high-quality starch products.
Renowned for its static yet highly efficient screening capabilities, the pressure arc screen expertly separates and grades wet materials under pressure. Its screen surface, meticulously crafted through specialized processing techniques, boasts a highly polished, smooth, and uniform finish. Equipped with screen wires that possess a razor-sharp edge and unparalleled wear resistance, it ensures that when starch milk with a specific pressure glides swiftly over its surface, it does so without causing any disruption or unsightly splashing, maintaining efficiency and cleanliness throughout.

Working Principle of Pressure Arc Screen Sieve Bend Screen
The starch emulsion is sprayed with precision from the nozzle onto the screen surface, maintaining a specific pressure and spray velocity. Seamlessly, the starch emulsion glides along the tangent of the arc screen surface, swiftly spreading out and uniformly enveloping the screen. It swiftly traverses through the screen's expanse. The emulsion's flow is strategically aligned at right angles to the screen's slots.
The emulsion experiences the dynamic synergy of centrifugal force, impact, gravity, coupled with the cutting prowess of the screen wireedge, all acting on the starch emulsified on the concave arc screen surface.
The wedge-shaped screen wire is akin to a keen blade. The starch emulsion collides with the sharp edge of the screen wire, transforming into a delicate liquid layer. This layer, alongside fine particles, seamlessly navigates through the screen's narrow slits, forming the undersize flow beneath; while other parts of the liquid
layer, along with coarse particles, journey over the screen surface, becoming the oversize and exiting elegantly via the overflow port.
- Achieve unparalleled efficiency in impurity separation. Expertly engineered to tackle high-pressure scenarios, the pressure arc screen excels at removing even the finest particles and impurities from starch slurry. This guarantees a pristine final product, remarkably free from any contaminants.
- Unmatched high screening efficiency. Ingeniously crafted, the curved design of the screen surface ensures a seamless, uniform flow of starch slurry. This design not only maximizes screening efficiency but also minimizes blockages and clogging, enhancing overall performance.
- Ingenious self-cleaning capability. Featuring a state-of-the-art self-cleaning design, the pressure arc screen efficiently dislodges trapped particles and impurities through a sophisticated backwash or flushing system. This innovation ensures continuous operation, eliminating the need for manual cleaning.
- Exceptional durability and longevity. Constructed from premium-grade stainless steel, the pressure arc screen boasts remarkable resistance to corrosion and wear. This durability translates into a prolonged lifespan with minimal maintenance, offering significant long-term value.
- Highly customizable for diverse needs. Adaptability is key with the pressure arc screen, available in customizable configurations to meet diverse starch processing demands. Options include varied screen and slot sizes, as well as pressure ratings, tailored to different operating conditions.
