Abstract
The invention provides an apparatus and method for improved mixing of yeast-raised and yeast-raised type dough. The device and method keep the dough cool by an improved structure and method for circulating coolant around a jacketed bowl, and by circulating cooled air through the spinning agitator roller bars. Better aeration of the dough and faster mixing time are achieved along with full water and flour absorption, and reduced operating temperatures by controlling placing of the agitator driveshaft in a carefully defined region. Finally, the invention provides a wiper for wiping the lip of the bowl to keep it clean of dough and to insure a proper seal along the bowl lip when a resilient, expandable bowl seal is used, and it provides a pneumatic seal for securely sealing the mix ingredients in the bowl during mixing.
