Utilizes simplified computer strategies to analyze, develop, and optimize industrial food processes. Discusses the integration and economic evaluation of the entire processing plant including effective use of water, energy, and raw materials; process profitability; and wastewater reduction. Offers detailed numerical examples for major food processes including heating, cooling, evaporation, dehydration, and thermal processing.
