Heat recovery/thermal energy storage for energy conservation in food processing
Based on energy consumption data compiled for 1974, 59% of the total energy consumed in the US food processing industry was thermal energy. The energy-consuming processes which utilize this thermal energy reject significant quantities of waste heat, usually to the atmosphere or to the wastewater discharged from the plant. Design considerations for waste heat recovery systems in the food processing industry are discussed. A systematic analysis of the waste heat source, in terms of quantity and quality is explored. Other aspects of the waste heat source, such as contamination, are addressed as potential impediments to practical heat recovery. The characteristics of the recipient process which will utilize the recovered waste heat are discussed. Thermal energy storage, which can be used as a means of allowing the waste eat recovery process to operate independent of the subsequent utilization of the recovered energy, is discussed. The project included the design, installation and monitoring of two heat recovery systems in a Gold Kist broiler processing plant. These systems recover waste heat from a poultry scalder overflow (heated wastewater) and from a refrigeration condenser utilizing ammonia as the refrigerant. The performance and economic viability of the heat recovery systems are presented.
