The aim of this work was to determine the engineering properties of hairless canary seeds (Phalaris canariensis L.) of the variety “CDC Maria”, and to determine the optimum combination of operating conditions of the dehulling process with a pilot-scale centrifugal dehuller. For the process optimization, a two-variable Doehlert design was used, analyzing the effect of impact dehuller rotor speed (peripheral speed 30.4 to 47.1 m/s) and seed moisture content (10 to 14% d.b.) by maximizing the dehulling ability (DA) and maintaining the production of fines by 3%. Under the used experimental conditions of 36.7 m/s (peripheral speed) and 10% d.b. (seed moisture), with a double pass through the dehuller, the maximum values of DA (94%) were obtained, with a removal of 98% of the hull and a fine production of 3%. The feasibility of canary seed impact dehulling was demonstrated, although a double pass through the dehuller is necessary.
