ABSTRACT:
Thin potato slices are fried to chips in a two-stage operation. In the first stage the slices are fried in oil to a moisture content of 3-10% by weight. This product is removed from the oil and the moisture content is reduced to 1.5-2.5% by weight in a second stage by the supply of heat. To reduce the moisture content in the second stage at least a portion of the frying vapors substantially without false air and having a temperature of at least 120.degree. C., is guided from the space above the oil of the first stage to the slices removed from the oil.
A suitable apparatus for frying thin potato slices to chips comprises an oil vessel, means to control the displacement of the slices from one end of the vessel to the opposite end, an inclined conveyor to remove the slices from the oil, a hood, at least one exhaust channel for the frying vapors and a drying device to reduce the moisture content of the slices to the desired final value, said drying device having at least one conveyor provided with openings, the space at one side of the conveyor being in connection with a flowing channel for at least a portion of the frying vapors formed above the oil and the space at the other side of said conveyor being in connection with an exhaust channel for said frying vapors.
