Sugar Industry Screens | Wedge Wire for Juice Extraction & Filtration


1、Product Matrix and Technological Highlights
Our product lineup is meticulously designed to integrate seamlessly with the intricate processes involved in sugarcane processing, 
ensuring optimal efficiency and minimal downtime.
 
Self-cleaning Filter: Suitable for crude filtration of sugar juice and wastewater pretreatment, with a broad flow rate adjustment range of 50–500 m³/h. Its notable benefits include reducing clogging risks, lowering maintenance costs, and enhancing production efficiency.

Wedge Wire Filter Cartridge: Applied in clarification, crystallization, and refining stages, featuring a pore size range of 50–300 μm. Key characteristics include maintaining low turbidity levels, extending filter lifespan, and improving product quality.
 
2、Precision Solutions for Process Pain Points
 
Sugarcane Pressing Segment:
The self-cleaning filter automatically intercepts fibers larger than 3mm, preventing evaporator pipe blockages and reducing shutdown cleaning frequency.

Juice Clarification Segment:
The wedge wire filter's 60° V-shaped structure prevents lime slurry sedimentation, maintaining a stable turbidity level ≤5 NTU, compared to traditional filter cloths which range between 12-18 NTU.

Crystallization and Honey Separation Segment:
Laser welding on wedge wires ensures a surface roughness (Ra) ≤0.4 μm, minimizing sugar crystal abrasion and increasing premium-grade yield by 22%.
 
3、Technical Advantages and Verified Data
 
Intelligent Control Module:
Dual-mode cleaning activation based on differential pressure and time, consuming less than 0.5 m³ water per cycle, significantly lower than competitors' average of 1.2 m³.

Material Innovation:
Super duplex steel 2507 filters demonstrate enhanced resistance to chloride corrosion, extending filter lifespan threefold under high (>800 ppm Cl-) sucrose juice conditions.
 
 
4、High-Impurity Raw Material Pre-treatment in the Sugarcane Pressing Segment
 
Combination of self-cleaning filters integrated with V-type wedge wire filters.
 
Technical Architecture:
Outer layer coarse filtration captures large particles like cane fibers and stones (over 99.5% interception rate). Inner layer fine filtration using 300 μm wedge wire filters retains mud and sand (particles >0.3 mm).
 
5、Lime Slurry Residue Control in the Sugar Juice Clarification Segment

Technical solution involving self-cleaning filters paired with 50 μm gradient wedge wire filters.
 
Collaborative Benefits:
Anti-scaling design allows lime slurry sediments to slide off naturally, avoiding filter clogging. Dual-stage interception reduces particle sizes greater than 100 μm first, followed by precise filtration to maintain turbidity at or below 5 NTU.
 
6、Protection of Sugar Crystal Integrity in the Crystallization and Honey Separation Segment
Innovative design featuring self-cleaning filters embedded with 316L wedge wire filters (surface Ra ≤0.4 μm).

Key Functions:
Laser welding ensures seamless filter seams, reducing sugar crystal damage rates to below 0.5%. The self-cleaning system maintains stable flow even under highly viscous sugar paste conditions (over 5,000 cP).

Efficient Suspended Solids Retention in Wastewater Recycling Systems
Technical route combining self-cleaning filters (with wedge wire filters) and cyclone separators.

Performance Breakthrough:
With wedge wire pore sizes at 80 μm, suspended solids (TSS) are intercepted down to ≤30 mg/L, meeting industry discharge standards of ≤50 mg/L.
 
 
 
In the production of sugar, the slot precision of wedge wire screen is very high
 
Widely used in the filtration process with high viscosity, because of its unique V-shaped structure, the product can achieve high precision filtration
 
Advantages:
       Long lasting, fewer change-outs
      High resistance to abrasion
     Low maintenance, easy to clean
