<p>Pastry products such as dough-nuts are manufactured by kneading a suitable dough, containing yeast at ambient temperature to bring the gluten to the optimum edible state. The dough is extruded from a deivce which can move backwards and forwards across an endless belt which advances so that regularly spaced pieces of dough are deposited on the belt. The latter takes the pieces of dough through zones heated by a high frequency electric field. The pieces of dough, which have risen rapidly during the space of 25-360 sec, are then conveyed to the frying apparatus. The finished products have smooth, golden crusts with a white, collar cellular internal structure.</p> |
