Abstract: The physical properties of Pueraria are quite different from other potatoes, such as large shape, high fiber content and surface grooves with sandiness. The mechanized processing of Pueraria starch cannot copy potatoes model, and the key equipment has its unique features. Most Pueraria starch enterprises are small and use potato processing equipment and technology, with few special equipment, unreasonable structure and low production efficiency, which is not conducive to the technological progress and development of Pueraria starch industry. The application scenarios of Pueraria starch processing technology and equipment are summarized based on the analysis of the domestic literature on potato starch processing and the application status of processing equipment. Taking the 500kg/h Pueraria starch processing process as an example, the structure and principle of key equipment and the problems of lack of advanced technology, high energy consumption and serious pollution in production are summarized. Suggestions were put forward to strengthen research on advanced technologies for Pueraria processing and planting, establish relevant standards and regulations, and improve comprehensive development and utilization, so as to provide reference for promoting industrial technology progress and largescale development.
