Abstract
Abstract Potato chips having texture and flavor characteristics of batch-fried potato chips are produced in a continuous process by conveying potato slices from an initial frying region having a temperature of from about 240° F. to about 320° F. through an intermediate frying region of decreasing oil temperature to a final frying region having a temperature of from about 210° F. to about 290° F., where the chips are continuously removed from the frying oil.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
180 words
A continuous process for the production of potato chips having texture and flavor characteristics of batch-fried potato chips comprising: (a) providing a vat of frying oil, the oil having initial and final frying regions and an intermediate frying region therebetween, the final frying region having a temperature below that of the initial frying region, the initial frying region having a temperature of from about 240° F. to about 320° F., the temperature of the frying oil decreasing from the initial frying region through the intermediate frying region to a temperature of from about 210° F. to about 290° F. in the final frying region; (b) continuously introducing potato slices into the frying oil at the initial frying region; (c) continuously conveying the potato slices in the frying oil from the initial frying region through the intermediate frying region to the final frying region to fry the potato slices and produce potato chips; and (d) continuously removing fried potato chips from the final frying region of the oil when the chips have a moisture content of 2% by weight or less.
