Housing body: Cylindrical stainless steel shell, square/circular flange ports on top and bottom for equipment interconnection.

Rotor impeller: Core rotating assembly fitted with 6–8 blades; blade tips can be embedded with wear resistant sealing strips (PTFE/polyurethane).

End covers & bearings: Side endcovers support rotating shaft; sealed bearings stop dust ingress into bearing cavities.

Drive assembly: Motor reducer unit (direct coupled or chain drive) delivering low speed rotor torque.

Shaft end sealing: Air seal/oil seal construction to block starch leakage along shaft journal. Inspection/service port: Side mounted access door for visual check and cleaning.

Principle

1. Filling: Raw material drops by gravity from top inlet and fills cavities between rotor blades.

Rotary conveying: Motor reducer drives rotor for steady rotation; material is carried from upper zone downwards.

Discharging: When blade cavity aligns with bottom discharge opening, material is discharged by gravity.

Airlock sealing: Very narrow clearance (0.15–0.25mm) between rotor blades and housing wall blocks airflow passage while discharging.

Stopping high pressure air backflow into upstream silo. has Superior airlock performance: Precise rotor housing fit inhibits air leakage and sustains stable system pressure.

Continuous uniform discharge: Volumetric metered feeding delivers even material flow.

Food grade material: 304/316 stainless steel housing, polished inner surfaces for food hygiene compliance. Anticaking self cleaning option: Dual rotor or anti stick coating variants available for sticky starch grades to minimise material adhesion.

Modular service friendly build: Blade seals, bearings and sealing consumables are easily replaceable.

Compact footprint: Small dimensions, flexible installation layout.
