Study on Waste Heat Recovery of Soy Sauce Production Process in Jinshilongmen Brewery

Abstract:

Considering characteristics of soy sauce production process and the equipment in JinShiLongMen Brewery, a series of energy-saving technology solutions, including secondary recovery of residual steam in steaming process, heat recovery in high temperature soy sauce cooling process, insulation of high temperature salt water tank and insulation of steam pipeline, was developed. After the implementation of these solutions, the system runs stably and experimental testing analysis shows that the annual amount of residual heat recovered by secondary recovery of residual steam in steaming process was 9.635×10⁸ kJ, amounting to reduce steam cost RMB79,100 Yuan, recovered in high temperature soy sauce cooling process was 1.839×10⁹ kJ, amounting to reduce steam cost RMB151,100 Yuan. The results show that the energy saving technologies achieved good economic and environmental benefits and are applied to the same industry.
