而這也無形中，擴大了碾米機的應用範圍，碾米機是由機殼、滾筒、米刀
、加工鬥、米mi篩shai等deng組zu成cheng。在zai工gong作zuo時shi
，將jiang稻dao穀gu倒dao入ru加jia料liao鬥dou打da開kai進jin口kou閘zha刀dao，稻dao穀gu流liu入ru碾nian白bai室shi和he滾gun筒tong的de空kong間jian。由you於yu滾gun筒tong轉zhuan動dong，稻dao穀gu受shou到dao很hen大da的de擠ji壓ya力li和he摩mo擦ca力li
，使shi穀gu殼ke脫tuo落luo

，並bing把ba穀gu殼ke碾nian細xi，米mi粒li擦ca白bai。在zai滾gun筒tong不bu斷duan轉zhuan動dong的de作zuo用yong下xia，通tong過guo滾gun筒tong上shang的de螺luo齒chi條tiao，米mi粒li被bei推tui送song到dao出chu口kou處chu
，從cong出chu口kou閘zha刀dao流liu出chu。穀gu糠kang從cong米mi篩shai漏lou入ru機ji殼ke底di下xia。碾nian米mi機ji出chu白bai率lv高gao
、碎米少

、取樣量大
、操作簡便快速、體現實際碾米效果，是糧食檢驗、科研

、教學、生產、收購等環節中必不可少的品質檢驗儀器。
