Abstract: Apparatus and method for slicing potatoes and washing or coating the potato slices wherein the slices exit a slicing mechanism and are directed between inner and outer spray rings that generate a pressurized water mist which washes the slices. The nozzles in the inner spray ring face the nozzles in the outer ring so that the pressurized water mist is formed in a predetermined area located between the rings. The high pressure water mist removes surface starch from the slices, and vibrating sieve arrangements disposed downstream of the slicing apparatus cooperate with a series of spray bars to further clean the slices. The apparatus of the invention is also used in a method of coating potato slices with a treating material.

Abstract: A novel process and apparatus is disclosed for producing potato chip products having less than twenty-five weight percent oil based on the total weight of an unseasoned chip. The process requires parfrying potato slices, dealing and partially dehydrating the slices with superheated steam and then further dehydrating the slices.

Abstract: Potato chips having batch-fried texture and flavor characteristics are produced in a continuous process in a significantly reduced time by conveying potato slices through an initial frying region having a temperature of from about 115.degree. C. to about 155.degree. C. (about 240.degree. F. to about 310.degree. F.) and then through a final frying region having a temperature of from about 165.degree. C. to about 185.degree. C. (about 330.degree. F. to about 365.degree. F.).
