Agitator/Paddle: Diameter 200-800 mm, Rotation Speed 10-60 RPM

Component Specifications

Definition

A mechanical component installed within ingredient feed hoppers that rotates to mix, blend, and facilitate the discharge of bulk materials. It prevents material segregation, compaction, and bridging by continuously agitating contents, ensuring consistent feed rates to downstream processes in food manufacturing.

Working Principle

Rotational motion driven by an external motor transmits torque to the paddle blades, which create shear forces and convective mixing within the hopper. This disrupts static material layers, breaks up clumps, and maintains homogeneous material properties for reliable feeding.

Materials

Food-grade stainless steel (AISI 304 or 316), FDA-compliant polymers (e.g., UHMW-PE), or coated carbon steel. Surface finish: Ra ≤ 0.8 μm for hygiene.
