Abstract
An apparatus is provided for cooking frozen french fries in which a supply of frozen potato pieces is held in a hopper and in which the potato pieces are continuously fed from the hopper at a predetermined, adjustable rate, by means of an upwardly slanting endless conveyor, into an enclosed bath of hot cooking liquid. Water vapor generated when the frozen potato pieces contact the hot liquid is removed by a vapor extraction system. A second endless conveyor is provided within the cooking liquid to carry the potato pieces submerged within the liquid while being cooked. The speed of the potato pieces through the cooking liquid is continuously adjusted, in response to cooking liquid temperature fluctuations, as necessary to provide french fries consistently cooked to the same degree. The french fries are automatically discharged from the apparatus.
