Abstract
A vending machine for providing french fried potatoes from dehydrated powder. Powder is metered into a cylinder of a rotatable, multi-cylinder cylinder block. Water is added when the block is rotated to the next stop. After mixing and two ready stations, the dough is extruded into hot oil in a cooking chamber. The oil is filtered and is then replenished from a reservoir. The dry powder and rehydrating stations are refrigerated. The vending machine includes absorption and adsorption filters to scrub the air while cooking to decrease oil odors.
