Work, white rice or brown rice by feeding device into the grinding chamber, under the effect of rotation of the grinding roller, rely on the friction rub from function get rice or brown rice on the surface of cortex, made a certain accuracy of polished rice, white rice after that comes the discharging mouth eduction closed, under the ground of rice bran rice sieve eduction. It has a simple structure, good performance, high output, easy installation, convenient operation, use a wide range of characteristics. Therefore applicable to the rural, small town food processing plant food such as rice processing. Key words : iron roller；wipe off type；whitening chamber；rice huller screen 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc356569121 1 绪 论 PAGEREF _Toc356569121 \h 6 HYPERLINK \l _Toc356569122 1.1 碾米工业在国家经济中的地位和作用 PAGEREF _Toc356569122 \h 6 HYPERLINK \l _Toc356569123 1.2 我国碾米工业的发展概况 PAGEREF _Toc356569123 \h 6 HYPERLINK \l _Toc356569124 1.3 碾米工业发展的方向 PAGEREF _Toc356569124 \h 7 HYPERLINK \l _Toc356569125 1.4 碾米工业的任务 PAGEREF _Toc356569125 \h 7 HYPERLINK \l _Toc356569126 2 碾米机类型及生产原理 PAGEREF _Toc356569126 \h 8 HYPERLINK \l _Toc356569127 2.1 摩擦擦离碾白型碾米机 PAGEREF _Toc356569127 \h 8 HYPERLINK \l _Toc356569128 2.2 碾削型碾米机 PAGEREF _Toc356569128 \h 8 HYPERLINK \l _Toc356569129 2.3 混合型碾米机 PAGEREF _Toc356569129 \h 9 HYPERLINK \l _Toc356569130 3 铁辊碾米机工作参数的确定 PAGEREF _Toc356569130 \h 9 HYPERLINK \l _Toc356569131 3.1 碾白压力 PAGEREF _Toc356569131 \h 10 HYPERLINK \l _Toc356569132 3.2 单位产量碾白运动面积 PAGEREF _Toc356569132 \h 12 HYPERLINK \l _Toc356569133 3.3 向心加速度 PAGEREF _Toc356569133 \h 13 HYPERLINK \l _Toc356569134 4 铁辊碾米机的主要部件 PAGEREF _Toc35
