This paper analyzes many key factors influencing the design of remanufacturing of food machinery. Based on the definition and characteristics of remanufacturing design, the remanufacturing design of some existing structures is improved by field investigation, so that the structure is more reasonable and the remanufacturing design principle of the moon cake automatic brush oil hole machine for innovative design. The face-to-face remanufacturing design maximi-zes the wealth of resources contained in waste food machinery and promotes a strategic approach to sustainable development.
