A tumbling bed of edible cores is formed which has a longitudinal axis extending from an entrance end to an exit end of the tumbling bed. Individual edible cores travel through the tumbling bed from the entrance end to the exit end by rotating in a generally helical path along the longitudinal axis of the bed. The edible cores are coated within the bed by repeatedly tumbling through both a wet zone(s) and a dry zone(s) formed within the bed. These wet and dry zones are formed, respectively, by spraying the surface of the tumbling bed with a hydrating liquid and by dusting the surface of the tumbling bed with a farinaceous powder. Both the wet and dry zones thus formed are generally rectangular, but not overlapping, zones with the major dimensions of these rectangular zones being substantially parallel to the longitudinal axis of the tumbling bed. Hydrating liquid and farinaceous powder are applied, respectively, to the wet and dry zones of the tumbling bed at rates which prevent aggregation of the edible cores and at rates which are suitable to form on the cores a dough-coating comprising flour, starch and sugar in a weight ratio of flour and starch to sugar of from about 0.5:1 to 30:1. The dough-coated edible cores are then cooked until crisp. |
