摘要: 采用自行设计制造MFT-300型机械冲击式粉碎机对面粉进行粉碎加工、分级,通过工艺参数调整,选出两种加工分级后的产品进行分析,结果表明:加工后的面粉平均粒径可达5.98μm,形貌呈球对称状;其蛋白质含量随粒径变细而增加,当D90小于10μm时,蛋白质含量骤然增大一倍多,从而为面粉的特殊使用要求提供了深加工的途径。

Abstract: The three flour samples were analyzed,which have been comminuted and classified by the CH-300 mechanic impact instrument designed by ourselves.The results showed that the average powder diameter of the finest flour comminuted was 5.98μm and powder shape approximated to sphere symmetry.The flour protein content increased as powder getting finer.It became two times more as power diameter D90 being smaller than 10μm ,thus providing a new way for high protein flour blending.
