Mixing Blades: Torque Capacity 150-500 Nm

Component Specifications

Definition

Mixing blades are critical rotating components within industrial dough mixer impeller assemblies, engineered to create specific flow patterns (radial, axial, or tangential) that ensure thorough ingredient incorporation, gluten development, and consistent dough texture through controlled shear and folding actions.

Working Principle

Operates on fluid dynamics and mechanical shear principles. As the impeller rotates, blade geometry (angle, curvature, surface area) directs dough movement, creating laminar and turbulent flow zones that facilitate ingredient dispersion, hydration, and structural development while minimizing dead spots and overheating.

Materials

Typically AISI 304 or 316 stainless steel (food-grade), with optional surface treatments like electropolishing (Ra ≤ 0.8 μm) for hygiene and cleanability. High-wear models may use hardened steel inserts or coatings.
