BCT62 BCT92 40° Food Grade Kneading Block | BC Twin Screw Extruder Spare Parts
BCT62 / BCT92 40° Food Grade Kneading Block is specially developed for BC62 and BC92 co-rotating twin screw food extruders. Adopting 40° staggered kneading disc structure, this element delivers mild-medium shear intensity, perfectly suited for starch gelatinization, raw material homogenization in food extrusion.
Different from high-angle high-shear kneading blocks, the 40° design controls melt temperature rise effectively and avoids overheating and scorching of starch-based food materials. All food-grade versions adopt high mirror polishing treatment, smooth surface without dead corners, easy to clean and meet food contact safety requirements. Internal spline fully matches original specifications, freely combined with conveying elements, barrier segments and reverse elements to optimize screw configuration for puffed snacks, textured protein, pet feed and fortified rice production.
- Moderate 40° medium-low shear mixing: Balanced dispersive & distributive mixing, prevent local overheating of starch materials.
- Promote sufficient starch gelatinization: Improve hydration and uniform mixing of powder, water and additives.
- Smooth self-cleaning surface: Mirror polished finish reduces material adhesion, lower risk of material carbonization.
- Stable material conveying performance: Maintain reasonable forward transport capacity, stabilize extrusion throughput.
- Modular assembly: Flexible combination with all BC series standard screw elements to adjust residence time and mixing intensity.

We provide standard BCT62 and BCT92 40° food grade kneading blocks and support customized length and disc combinations. Standard items have short delivery cycle. When sending inquiry, confirm extruder model, screw layout drawing, raw material type and cleaning requirements. All screw elements pass dimension inspection, hardness test and surface roughness testing before shipment.
Q1: Can these kneading blocks replace original spare parts directly?
A1: Yes. Outer diameter, spline geometry and disc profile comply with OEM standards, plug and play.
Q2: Why choose 40° kneading block for food extrusion instead of 45° / 60°?
A2: 40° generates lower shear heat, ideal for starch food which is easy to scorch; 45° suits general plastic compounding; 60° high shear easily causes starch degradation.
Q3: What material to select for food-grade requirement?
A3: 316L stainless steel for acidic, high moisture food; WR5 / SAM26 for high fiber, abrasive feed raw materials.
Q4: Can I customize the number of kneading discs and block length?
A4: Customization supported. We provide screw layout optimization suggestions based on your production formula.
Q5: Production capacity and warranty?
A5: Monthly output:8000–12000 PCS. Standard delivery:3–7 working days; customized parts:7–15 working days. 12-month warranty under normal operation.
