  • Patent number: 6276919
    Abstract: An automated pretzel forming machine that produces fresh unbaked pretzels with hand formed characteristics by extruding premixed dough onto a folding table. This table is moved by a bi-directional positioning stage, forming the unfolded and untwisted pretzel shape. The folding table twists the ends of the extruded dough rope then folds the twisted portion on top of the main body of extruded dough resulting in the classic hand twisted pretzel shape. The twisted and folded pretzel is transferred from the folding table through the use of a lift and rotate unit and is subjected to a patterned soda spray and salted before being unloaded from the lift and rotate unit to an existing conveyor oven.
