Abstract

Utilizing waste heat that is rejected from thermal processes can greatly enhance the industry's energy balance. Identifying potential waste heat sources in the food and beverage processing industry and making estimations for their possible utilization can be an extremely challenging undertaking. To determine waste heat potentials in the food processing industry and to select an optimal technology for its utilization a novel systematic methodology based on the comprehensive energy audit and mathematical optimization has been developed. The developed mixed integer nonlinear programming model incorporates all novel and the most commonly employed technologies to utilize waste heat.

The developed systematic methodology is tested on a case study, of a milk and dairy production facility. Obtained results have shown that up to 53 % of the available waste heat can be used in the scenario of limited investment costs. Otherwise, in the scenario when investment costs are not set as a limitation, 75 % of waste heat can be used, according to plant demands. Harmonising production processes is necessary to use all the waste heat. The developed systematic methodology can be applied to any food processing industry and other facilities producing waste heat because it presents a universal approach.

选择食品加工业余热利用最佳技术的系统方法学

利用热加工过程中排出的余热可以大大提高行业的能源平衡。在食品和饮料加工业中确定潜在的废热源并对其可能的利用率进行估算是一项极具挑战性的工作。为了确定食品加工业的余热潜力，并为其利用选择最佳技术，我们开发了一种基于综合能源审计和数学优化的新型系统方法。所开发的混合整数非线性编程模型包含了所有新型和最常用的余热利用技术。结果表明，在投资成本有限的情况下，最多可利用 53% 的可用余热。否则，在投资成本不受限制的情况下，根据工厂需求，75% 的余热可被利用。要利用所有余热，必须协调生产流程。所开发的系统方法适用于任何食品加工业和其他产生余热的设施，因为它提供了一种通用方法。

期刊介绍： Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics. The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management. Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
