Engineered for Harsh Chemical Cooking Environments The cookie basket is built to endure continuous cooking conditions in kraft and soda pulping systems. Its structure uses 8×16 mm or 7×16 mm wedge wires, enabling strong mechanical support and open flow channels. The design withstands both temperature fluctuation and aggressive chemical exposure. Fluid passes through with minimal resistance, allowing liquor to circulate efficiently and uniformly. Unlike slotted screens, the basket’s wedge wire structure prevents fiber entanglement and surface fouling. In long-cycle pulping, it ensures consistent chemical distribution and fiber processing while resisting deformation over time.
Flexible Sizing for Industrial Integration To accommodate diverse cooking equipment, the wedge wire basket can be manufactured with diameters up to 1715 mm and height up to 2205 mm. This allows seamless integration into both new and legacy systems. The design maintains slot accuracy and mechanical balance across full-size formats, ensuring even flow and pressure control. ICM offers customized configurations that meet OEM standards or on-site retrofit needs. Slot openings, support ring spacing, and inlet geometry are tailored for optimal circulation. As a seasoned wedge wire basket manufacturer, ICM ensures that form and performance match operational scale and system demands.
Resistant to Chemicals and Thermal Stress The basket uses uncoated stainless steel, ensuring resistance to alkaline and acidic solutions used in fiber digestion. The wire basket weaving method locks wires in place without welding, preserving structure under repeated chemical cycles. This makes the basket ideal for high-frequency cleaning and exposure to hot black liquor or recovery solutions. Even after prolonged operation, slot openings remain stable, supporting predictable filtrate flow. Operators benefit from longer service intervals and fewer disruptions. It’s a reliable solution for pulp facilities seeking durable screening under constant chemical attack and thermal cycling.
Product Advantages
Heavy-Gauge Wire Enhances Structural Life Using thick 8×16 mm or 7×16 mm wedge wires, the basket maintains shape under pulping stress. Its reinforced frame resists bending, cracking, and fatigue caused by rapid flow and rotating elements. Compared to lighter screens, this format reduces failure risk and prolongs service life. ICM, as a leading wedge wire basket supplier, produces baskets with minimal slot deviation and reinforced vertical load resistance. This design is critical in systems where stability and uptime matter. Fewer replacements mean fewer process interruptions and better lifecycle economy for pulp producers.
Large-Format Build Simplifies Installation The ability to produce baskets with dimensions exceeding 2 meters in height streamlines system design. With fewer joins or panels, pressure is evenly distributed across the surface. The one-piece body improves flow uniformity and reduces bypass issues. Installation teams benefit from faster alignment and fewer leak points. As a flexible wedge wire basket manufacturer, ICM matches flange, seal, and structural specifications to site needs. Whether for new systems or upgrade projects, this simplifies integration and shortens commissioning time, especially in fast-moving project cycles.
Uncoated Stainless Reduces Cleaning Downtime Without external coating layers, the stainless-steel basket handles frequent wash cycles and harsh chemicals without degradation. This avoids surface peeling and slot obstruction over time. Operators can clean the basket using standard CIP or flushing methods without fear of wear-induced flow restriction. In high-turnover pulping, this feature reduces cleaning frequency and ensures stable performance between maintenance rounds. It’s a practical choice for teams seeking a wedge wire basket that performs reliably without special upkeep or protective surface renewal.
Use Scenarios
Kraft Cooking Tower in Large-Scale Mills In kraft pulp production lines, the cookie basket supports high-throughput white liquor circulation. Its large wire openings allow smooth liquor movement while retaining fibers for uniform reaction. Even under 170 °C heat and continuous flow, the wedge wires retain structure and slot shape. The basket minimizes pressure loss and supports stable discharge. Operators report fewer cleaning intervals and improved flow consistency compared to traditional slotted screens. It’s an ideal fit for systems requiring reliable fiber screening over long cooking cycles.
Alkaline Batch Digestion in Soda Pulp Plants In soda pulping, consistent liquor exposure and rinse flow are essential. This wedge wire basket enables caustic solution transfer through precise slots, ensuring even fiber contact. Its stainless construction prevents damage from repeated exposure to high-pH fluids. With sizes tailored to fit reactors directly, no adapter rings or spacers are needed. After multiple chemical cycles, the basket maintains its structural profile, reducing performance drift. Its quick-release design simplifies inspection and replacement when needed, supporting continuous pulping operation.
Recycled Fiber Cooking in MDF or Fiberboard Systems For fiberboard manufacturers using mixed pulp sources, the wedge wire basket handles contaminated or irregular fiber feed without clogging. Its thick wire construction blocks heavy debris while maintaining high flow rates. The mechanical lock structure withstands strong turbulence from recirculation pumps. Technicians note improved liquor recovery and reduced rotor drag. With no welded seams to crack, the basket survives more stress cycles than traditional designs. It is now the standard component in many upgraded cooking systems focused on energy and cost efficiency. About Us
