Abstract
The food industry, as a significant source of global energy consumption and carbon emissions, plays a crucial role in the research and implementation of energy-saving and emission-reduction technologies. This study aims to explore key technologies and their application effects in the field of food engineering by integrating literature analysis, case studies, and experimental validation to systematically evaluate the feasibility and effectiveness of various energy-saving technologies and emission-reduction strategies. Typical food processing technologies were selected as research subjects, with a focus on analyzing the practical applications of heat recovery, water resource recycling, and renewable energy substitution, along with the proposal of optimization solutions. The results indicate that the adoption of integrated energy-saving measures can reduce energy consumption by over 25% while decreasing greenhouse gas emissions by approximately 30%. The innovation of this study lies in introducing the concept of multi-technology integration into the food engineering domain and developing an energy-saving and emission-reduction assessment tool tailored for small and medium-sized enterprises, thereby providing technical support for the green transformation of the industry. The findings demonstrate that through technological innovation and management optimization, the food industry can significantly enhance resource utilization efficiency, achieving a win-win goal of economic and environmental benefits.
