ABSTRACT:
A process control scheme for use with an extruding apparatus for cooling and heating aerated or compressible compounds that are edible. Broadly, the process includes providing a mixture to an inlet of the extruding apparatus, monitoring the pressure profile across the extruding apparatus, moving the mixture through the extruding apparatus with at least one auger while subjecting the mixture to a thermo-dynamic process, automatically altering speed of the at least one auger if the pressure profile across the extruding apparatus is outside a predetermined range, and moving the mixture through an outlet of the extruding apparatus. The process may also include monitoring temperature of a thermodynamic liquid, monitoring the load of an auger motor, and automatically altering the temperature of the thermodynamic liquid and the load of the auger motor if one of either the temperature of the thermodynamic liquid and the load of the auger motor is outside a predetermined range.
