Dry Processing

Rotary feeders

By Wayne Labs, Senior Contributing Technical Editor

ACS Valves’ Aero-Flow Series rotary feeders for food and bakery processing applications provide an air-assisted material introduction to pneumatic conveying systems. The feeders use a proprietary, dual-induction endplate architecture to introduce pressurized air from both endplates into the rotor pockets carrying process material. The feeder housings are available in cast iron and 304 or 316 stainless steel; they come in 17 1/2-in. or 21 1/8-in. heights. The feeders operate in applications with pressure differentials up to 15psig and temperatures to 500ºF. The Aero-Flow Series 10-vane rotor is precision machined with beveled vane tips and sides. Other rotor configurations include Teflon coated and adjustable tips. Adjustable rotor tips are available in hardened steel or stainless steel. Rotor-housing interior surface coating options include hard chrome, tungsten and Teflon.
