Stainless steel 304 grade Wedge Wire sieve bend screen for food processing

The Sieve Bend is also known as a DSM Screen after the Dutch State Mines introduced the product. Sieve Bend Screens are ideal for sizing and dewatering applications to remove solids from liquids, or in solid/solid separation for dry feed situations.

Sieve Bend Screens can be manufactured in a variety of widths, arc lengths, apertures or wedge wires to suit the flow rate and material being separated. Although most applications require Static Sieve Bends, “Cross Flow”, “With Flow” and “Vibrating” Sieve Bends can also be manufactured.

Characteristics of the curved screen

A continuous slot opening which significantly increases the available open area, thus providing a greater access to the water bearing zone.

A 'V' shaped wedge wire which avoids clogging and ensures uninterrupted flow.

A uniform and efficient well development due to the continuous slot opening.

Offering great strength. precision, long service life.

Wedge Wire Sieve Bend Screen Working Principle

The feed slurry is directed vertically and tangentially over the full width of the upper screen surface. The slurry flows down the concave surface at right angles to the openings between wedge profiled wires. Due to the drag on the slurry passing over the wedge wire, a thin layer on the underside is deflected and passes out between the wires. The fact that the size of particle passing through the screen is always smaller than the opening, gives the screen good non-clogging properties.

Production of a Sieve Bend AssemblyIn a typical feed situation the leading edge of the wedge wire removes the water and fine particles through the screen up to the cut point size, as the oversized particles move across the top of the screen. Static Sieve Bends require little or no maintenance in their operation and need only small head heights to operate.

Applications of Stainless Steel 304 Wedge Wire Sieve Bend Screen for Food Processing

Stainless steel 304 wedge wire sieve bend screens are widely used in food processing industries where efficient solid-liquid separation, material recovery, and continuous screening are required. With a smooth curved screening surface, high open area, and corrosion-resistant stainless steel construction, sieve bend screens help improve process efficiency while maintaining strict hygiene requirements in food production environments.

Sugar Processing Industry

In sugar manufacturing, wedge wire sieve bend screens are commonly used for juice clarification and bagasse separation processes. During sugar extraction, the screen helps remove suspended fibers, coarse particles, and insoluble impurities from sugar juice before further purification and evaporation. The continuous slot design provides efficient filtration while reducing clogging caused by fibrous materials, helping improve downstream equipment performance.

Flour and Grain Processing Industry

In flour milling and grain processing, sieve bend screens are applied for starch recovery, slurry separation, and removal of unwanted solid particles. The curved wedge wire surface allows fine particles and liquid to pass through efficiently while retaining larger materials, improving separation accuracy and reducing material loss during processing.

Starch, Beverage and Other Food Processing Applications

Beyond sugar and flour production, stainless steel wedge wire sieve bend screens are also used in starch processing, fruit and vegetable juice production, brewing, and other food industries. They are suitable for applications involving pulp separation, wastewater pre-treatment, and product recovery, where reliable performance, easy cleaning, and long service life are essential.

Manufactured from stainless steel 304, these sieve bend screens provide excellent corrosion resistance and meet the demanding requirements of food processing environments. Their high throughput, low maintenance design, and efficient separation performance make them an ideal solution for continuous screening and dewatering applications.

Wedge Wire Sieve Bend vs Perforated Screen

Wedge wire sieve bend screens use V-shaped profile wires to create continuous slot openings, providing higher open area, better flow capacity, and reduced clogging compared with perforated screens. Their curved design improves dewatering and solid separation efficiency, making them ideal for wastewater, food processing, mining, and other continuous screening applications.
