ABSTRACT:
A continuous process for making fat-free potato chips without using any cooking oil whatsoever. Chipping potatoes are prepared, sliced, continuously monolayered onto a conveyer and squeegeed to remove the excess starch and moisture. The slices are initial cooked on independently controlled conveyers in a primary 3-zone oven where they are first radiant heated and then subjected to two stages of forced air convection heating by driving the air into both surfaces of the slices simultaneously as the moisture content is reduced to 15%. The slices are then final cooked in a dielectric heater where an even controlled heat is applied in two tandem drying zones where the potato slices are subjected to long wavelength (65.8 ft.) radio frequency (15 mhz) waves from two 20 kw transmitters which reduce the moisture content of the finished slices to 7%. The finished potato chips are seasoned and packaged and have the texture, appearance and mouthfeel of deep-fat fried potato chips.
