ABSTRACT:
A thickness control system for a high speed tortilla sheeting machine automatically adjusts a pinch point gap between a pair of sheeting rollers to maintain a generally uniform thickness of the produced "masa" (i.e., corn dough) sheet. The control system includes a pair of sensors, a controller, and a pair of actuators. The sensors continuously monitor the distance to the surface of a produced masa sheet. The controller derives from the sensor output signal a measurement of the thickness of the produced masa sheet, and compares this measurement to a preset thickness. The controller then directs one or more of the actuators to change the distance between the two sheeting rollers of the tortilla sheeting machine as necessary to produce a masa sheet at the desired preset thickness.
