The possibility for utilization of waste heat from processes in the food industry is presented in this paper. The need for reuse of waste heat comes from the fact that energy consumption in industrial companies is uneconomical and that environmental pollution has increased. Therefore, one of the method of reuse of waste heat that is applicable in industrial processes is presented in the paper. Potential primary energy savings is presented by implementing the waste heat recovery in the food factory. The paper presents a simplified solution proposal for installation of heat exchangers with the aim of utilizing the waste heat of the refrigerant. The results showed that by the implementation of simple heat recovery significant annual fuel energy savings can be achieved as well as fuel cost savings.


Keywords: Waste heat, heat recovery, energy efficiency, food industry.
