Float-frying and dockering methods for controlling the shape and

Abstract

A method for producing fried snack products of controlled shape comprises introducing dough pieces into a shallow depth of frying oil and allowing the dough pieces to travel unsupported through the oil while frying to a set shape. The shallow depth of the oil prevents the pieces from overturning in the oil while frying, so they form a controlled shape. In one embodiment, a two-layer sheeted dough is formed from dissimilar potato-based dough layers adhered and cut into layered dough pieces introduced into the shallow oil depth. The first layer is on the bottom and the second layer is at the top of each dough piece. The layered dough pieces maintain their original orientation in the shallow oil depth as they fry to form a fried potato skin product having a convexly curved upper layer and a concavely curved bottom layer. The dough pieces are partially fried in the shallow oil depth to set the curved shape, after which the partially fried pieces are finish-fried in a greater depth of frying oil. The technique of preventing overturning in the fryer includes maintaining smooth oil flow through the shallow portion of the fryer and controlling the velocity of the pieces passing through that portion of the fryer in relation to the velocity at which the pieces are fed into the fryer. In another embodiment of the invention the dough pieces are dockered by a rotating semi-flexible bristle brush to form dockering holes in the dough to prevent puffing during frying. The flexible bristles increase the point density of dockering holes in the dough while avoiding sticking or wrinkling of the dough during the dockering step.
