A can extractor for atmospheric rotary cookers and coolers has a clover wheel, a star wheel and a star wheel flange made of stainless steel. The clover wheel and star wheel are aligned and coupled to a sleeve rotating on a stationary shaft. The star wheel is coupled to the sleeve using an adjustable keyless hub/shaft locking device. The clover wheel and star wheel are spaced to accommodate bulging or deformed cans. A center discharge chute is supported on the rotating sleeve with a plastic bushing. Cans from the reel of a cooker/cooler are positioned with a can stripper between the star wheel and clover wheel while the reel rotates the clover wheel. The stainless steel components reduce scratching and eliminate transfer of rust to cans. A plastic clover wheel and a plastic star wheel flange are disclosed that do not scratch or transfer rust to the cans.
