1、全自动马铃薯淀粉含量测定机设摘要摘要随着人民生活水平的不断提高，高档次的食品需求量越来越大。由于精制马铃薯淀粉它成糊后粘度高、成糊稳定、晶莹透明、有较强粘弹性，是举世公认的食品行业伟大的“绿色建筑材料”！同时它还广泛的应用于化工、纺织、医药、饲料、造纸、石油等行业，因而对它的淀粉含量要求也就越来越高。设计马铃薯淀粉仪也就迫在眉睫，在设计马铃薯含量淀粉仪的时候，用两个步进电机提供动力，确保旋转机构位置精度，电机与旋转装置的连接是通过齿轮直接啮合。电机1通过齿轮来控制旋转机构的旋转，再通过旋转装置上的挂钩获取载物块送至测量装置。电机2同
2、样也是与旋转装置2齿轮直接啮合，通过旋转装置上的挂钩从测量装置获取试样，再通过逆旋转摘除试样，完成整个动力传递过程。马铃薯淀粉含量的测定，传统的马铃薯淀粉含量的测定劳动强度大、效率低、人工误差大，目前我国的马铃薯淀粉含量的自动化机械监测水平相对落后。本设计针对这一问题，设计了马铃薯淡粉含量自动测定仪，实现了马铃薯淀粉含量测定的自动化，提高了测定效率。关键词：马铃薯；淀粉含量测定；步进电机；密度测淀粉IAbstractTheDesignofAutomaticPotatoStarhContentDeterminationMachineA
