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.

摘要： 葛根的物理特性与薯类有较大的不同，外形粗大、纤维含量高、表皮粗糙夹砂多，葛根淀粉的机械化加工不能照搬薯类模式，关键设备有其特别之处。葛根淀粉企业规模小，大多数企业沿用薯类加工设备和工艺，专用设备配套少、结构不合理、生产效率低，不利于葛根淀粉产业的技术进步和发展。通过对国内薯类和葛根淀粉加工文献和工艺设备应用现状的分析，以500kg/h葛根淀粉加工工艺流程为例，简述加工工艺的基本要求、关键设备的结构原理、针对性的技术改进措施，指出当前行业内仍存在先进设备缺乏、耗能高、环境污染等问题，提出加强葛根加工及种植先进技术的研究、建立健全相关标准规范、提高综合开发利用等建议，为促进产业技术进步和规模化发展提供参考。
