Abstract
Abstract A process is provided for the continuous production of a uniform density pretzel dough. The ingredients of the pretzel dough are continuously supplied to a continuous operating assemblage and the dough is continuously produced, utilizing a relatively short retention time in the mixer. Within the continuous operating assemblage are mixing units and conveying units in ratio of approximately three to one, respectively.
