1、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
2、同样也是与旋转装置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ITheDesignofAutomaticPotatoStarhContentDeterminati
