摘要：搅拌机是工农业生产中应用非常广泛的一类通用设备，尤其在农产品和食品加工业中发挥着重要作用。目前在工农业生产中应用的搅拌机种类和规格很多，但是没有适合小型淀粉加工厂用于搅拌淀粉的产品。本文设计了一种能适应于搅拌淀粉的小型搅拌机，所设计的搅拌机为立式，采用平直型桨叶。浆叶式搅拌机具有以下特点：结构简单，容易制造；混合效果较好；局部剪切作用强，不易发生乳化作用；适用性广。小型浆叶式搅拌机能够满足需要，且在如今的能源社会，对于提倡新工艺、看重技术含量，使用专业化机械，为食品等生产企业扩大市场，提高质量，减耗增效具有积极意义。

Abstract: The mixer is an extremely widespread kind of general equipment in the industry and agriculture production, especially playing the vital role in the agricultural product and food processing industry. At present there are many types and specifications of the mixers in the industry and agriculture production, but there is no suitable small product which stirring the starch for smaller factory to use. This paper designs one smaller kind of mixer that can be able to adapt in the agitating starch, the design of the mixer is vertical and the blades are straight form. The mixer has following characteristics, the structure is simple and easy to make, the mix effect is well, the partial shear action is enough, not easy to have the emulsification, the serviceability is broad. The smaller mixer can meet the needs in the present energy society, there is a positive significance in this mixer such as advocating the new craft, regarding important technology content, using specialization machinery and for production enterprises expands the food markets, improves the quality and reduce consumption and increase efficiency
