Introducing the 120° Pressure Arc Bending Screen, expertly crafted for the Starch Industry
The Pressure Arc Screen, also acclaimed as the Pressure Arc Sieve Bend Screen or DSM Sieve Bend Screen, stands as a pinnacle of advanced screening equipment. Renowned for its versatility, this screen plays a pivotal role in starch processing, accommodating multi-stage counter-current rinse operations with ease. In the intricate starch production process, this equipment excels at the precise separation of starch from both germ and fiber, marking itself as an indispensable asset in the realm of starch production.
This remarkable Pressure Arc Screen epitomizes static and efficient screening prowess. Designed to separate and grade wet materials seamlessly under pressure, its screen surface benefits from meticulous processing methods, delivering a highly polished finish. The result is a smooth and uniform screen surface where each wire boasts a razor-sharp edge and exceptional wear resistance. As starch milk flows swiftly across the screen surface, propelled by a specific pressure, it achieves a tranquil passage with neither fluctuation nor splashing, ensuring an optimal screening experience.

Working Principle of Pressure Arc Screen Sieve Bend Screen
The starch emulsion technique involves precision spraying from the nozzle onto the intricately crafted screen surface, executed with meticulous control at specific pressures and optimized spray speeds. The starch emulsion, expertly directed along the tangent of the arc screen, gracefully spreads across the surface, ensuring a uniform, seamless coverage before briskly flowing through the finely engineered screen. As it progresses, the flow of the starch emulsion aligns perfectly at right angles to the precisely designed screen slit. The dynamic force is a symphony of centrifugal force, impact, gravity, and the incisive cutting edge effect of the screen's wire.
The meticulously shaped wedge wire acts as a precise instrument. When met by the starch emulsion, it slices with precision, bringing the starch to a razor-thin liquid layer, effectively separating materials.This fine layer, along with tiny particles, navigates through the minute screen slits with remarkable efficiency,
streamlining into the bottom flow, creating what is termed as the 'undersize', while certain liquid layers and larger particles continue their journey across the surface, culminating as the 'oversize' and exit gracefully through the overflow port. This sophisticated system optimizes separation efficiency, ensuring only the finest results for a variety of industrial applications. The seamless integration of these forces and design elements embodies the pinnacle of filtration technology,
making the Wedge Wire Screen an indispensable asset for industries seeking unparalleled precision and efficiency. Experience the innovative prowess of Hebei Slot Filter Technology Co., Ltd., through this remarkable product.
- Efficient separation of impurities. The pressure arc screen is meticulously engineered to handle high-pressure environments, expertly removing fine particles and impurities from the starch slurry. This innovation guarantees a final product that is impeccably clean and free from contaminants.
- High screening efficiency. The ingeniously curved design of the screen surface promotes a harmonious flow of starch slurry, optimizing screening efficiency while effectively minimizing any risk of blockages or clogging.
- Self-cleaning. Designed for self-sufficiency, the pressure arc screen automatically cleans itself. Trapped particles and impurities are efficiently removed by an advanced backwash or flushing system, ensuring uninterrupted operation without manual intervention.
- Durable and long-lasting. Crafted from premium-grade stainless steel, the pressure arc screen boasts superior resistance to corrosion and wear, promising years of reliable performance with minimal maintenance required.
- Customizable. Tailor the pressure arc screen to fit the unique demands of any starch processing application. With options for diverse screen sizes, slot dimensions, and pressure ratings, it adapts seamlessly to various operational conditions.
