A energy cost reduction of the Sorrento Cheese Co. Inc. cheese/whey powder process has been completed. Of Particular interest were the opportunities for utilizing heat pumps for energy cost reduction or other profit improving uses. Pinch Technology was used to identify heat recovery, heat pumping, process modification and congeneration options. Pinch Technology provides a thermodynamically consistent base from which the relative merits of competing cost reduction options can be assessed. The study identified heat recovery opportunities which could save $198,000/yr at an over all payback of 26 months. Individual project paybacks range from 18 to 36 months. The use of heat pumps in the form of MVR and TVR evaporators is well established in the dairy industry. For this process, which already incorporates a TVR evaporator, no additional cost effective opportunities for utilizing heat pumps were identified. It is felt that the results obtained in this study are applicable to other cheese/whey powder manufacturing sits. This study, and others, indicate that reductions in thermal energy consumption of 10--15% can be expected. Also the use of MVR and TVR evaporators is appropriate. 10 figs., 1 tab.
