Summary

SKIM MILK IS USED AS A MODEL MATERIAL. IT IS SHOWN THAT THE LOWEST COST OF PRODUCTION CORRESPONDS TO THE HIGHEST PRODUCTION RATE. THIS OCCURS WHEN LARGE SAMPLE THICKNESSES ARE USED, THE CHAMBER PRESSURE IS AT ITS LOWEST VALUE AND THE UPPER AND LOWER HEATING PLATES ARE INDEPENDENTLY CONTROLLED SUCH THAT THE MELTING AND SCORCH CONSTRAINTS ARE BOTH ENCOUNTERED AND HELD DURING THE FREE WATER REMOVAL PHASE. THEREFORE, THE OPERATIONAL REGIME THAT PROVIDES THE SHORTEST DRYING TIMES DURING THE FREE WATER REMOVAL PHASE WILL PROVIDE THE SMALLEST PRODUCTION COSTS AND HIGHEST CAPACITIES.
