Component Specifications

Definition
Mixing blades, also known as fins, are precision-engineered components installed within mixing drums to facilitate the thorough blending, stirring, and homogenization of ingredients. These blades create controlled turbulence and shear forces to ensure uniform consistency, prevent sedimentation, and optimize processing time in industrial food manufacturing applications.
Working Principle
Mixing blades operate by rotating within the mixing drum, creating fluid dynamics that include axial flow for top-to-bottom movement, radial flow for outward dispersion, and tangential flow for circumferential mixing. The blade geometry determines the balance between shear forces (for breaking down particles) and bulk flow (for overall homogeneity), with optimized designs minimizing dead zones and maximizing energy efficiency.
Materials
Food-grade stainless steel (AISI 304 or 316L), with optional coatings like PTFE for specific applications. Hardness: 150-200 HB, Surface finish: Ra ≤ 0.8 μm for cleanability, Corrosion resistance: Passivated per ASTM A967.
Technical Parameters
  • Blade Angle 30-60 degrees adjustable
  • Mounting Type Bolted or welded flange
  • Blade Diameter 200-800 mm
  • Rotation Speed 20-150 RPM
  • Number of Blades 2-6 per shaft
  • Power Consumption 0.5-5 kW
Standards
ISO 14159, DIN 11850

Frequently Asked Questions

What maintenance is required for mixing blades?

Regular inspection for wear, cleaning after each batch to prevent contamination, and torque checks on mounting bolts. Blades should be replaced when wear exceeds 10% of original thickness.

Can mixing blades be customized for different viscosities?

Yes, blade geometry (pitch, width, number) can be optimized for low-viscosity liquids, high-viscosity pastes, or particulate mixtures through computational fluid dynamics analysis.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
