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.

A method of controlling an extruder as it processes organic dry material and moisture into an extrudate comprising the steps of: sensing the temperature of the extrudate immediately as it is separated from the extruder; sensing the pressure inside the extruder at a plurality of locations along the path of the material as it traverses the extruder; controlling the input of material, moisture, and heat into the extruder in response to said sensed temperature and pressure in order to maintain pre-determined values of temperature and pressure to thereby maximize throughput of desirable extrudate.
