Claim Text:
1. A system for extrusion of dough, the system comprising: an auger; a metering pump comprising an input; a first motor for actuating the auger to transfer dough to the input of the metering pump; a first encoder for reading a position or speed of the first motor and for transmitting a signal associated with the position or speed of the first motor; a controller adapted to receive the signal from the first encoder to control operation of the first motor, wherein the controller operates the first motor to at least partially counteract a variance in a pressure of dough at the metering pump by driving the first motor in accordance with a repeating wave pattern profile to adjust the speed of the auger throughout at least every single revolution of the auger in accordance with a first set of intervals, the pressure of the dough being detected in accordance with a second set of intervals; a pressure sensor configured to detect the variance in the pressure of dough at the input of the metering pump and adapted to transmit a signal associated with the variance in pressure to the controller, wherein the controller operates the first motor based on a signal associated with the variance in pressure and based on the signal received from the first encoder; a second motor for actuating the metering pump; a cutting device adapted to receive dough from the metering pump; a third motor for actuating the cutting device; a second encoder for reading a position or speed of the second motor and for transmitting a signal associated with the position or speed of the second motor; and a third encoder for reading a position or speed of the third motor and for transmitting a signal associated with the position or speed of the third motor, wherein the controller operates the first, second, and third motors based on the signal associated with the variance in pressure and based on the signals received from the first, second, and third encoders.
