Abstract: A peeling machine particularly for peeling tuburous vegetables such as potatoes and onions includes a vessel with side walls containing peeling mechanism and a rotatable bottom for tumbling the vegetables within the vessel against the peeling mechanism. Near the bottom, adjacent the center of the vessel and directed generally outward are one or more nozzles into which air under pressure is introduced. Near the top of the vessel located adjacent the side walls, are one or more spray nozzles through which water may be introduced. The introduction of air and/or water is selective, and can be adjusted according to the type of vegetable, and the amount thereof, being peeled in the machine.
