Abstract
An automatic control for an extruder has a temperature sensor which monitors the exit temperature of the extrudate and several pressure transducers which monitor the pressure within the extruder to control the cooking of the mash inside the extruder to ensure production of high quality extrudate. The controller monitors and controls the temperature and moisture content of the mash in the extruder by controlling the input of various ingredients and also the cooling or heating of the mash near the exit of the extruder through a heat exchanger.
