在面粉機械的生產中，不可避免會遇到一些雜質，這些雜質有可能是物料中帶來的，也有可能是原糧儲藏不當產生的，也可能是在生產過程中產生的廢料，但是無論雜質如何出現，工作人員都需要及時的清理這些雜質，否則就會對面粉機械的生產造成影響。

In the production of flour machinery, it is inevitable to encounter some impurities. These impurities may be brought by materials, improper storage of raw grain, or waste generated in the production process. However, no matter how the impurities appear, the staff need to clean up these impurities in time, otherwise it will affect the production of flour machinery.

比如石磨面粉機械加工的小麥中不能含有像是豌豆，發霉的種子，其他糧食作物等，也不應該含有石塊，鐵塊，煤石等無機雜質，這些雜質的顏色比較深，很容易在碾磨的過程中進入到面粉當中，影響到面粉的顏色和含麩量，增加其中的黑點。石磨面粉機械要做好小麥的清理工作，這是不可或缺的。

For example, the wheat processed by stone milling flour machine should not contain peas, moldy seeds, other food crops, etc., nor should it contain stone, iron, coal and other inorganic impurities. The color of these impurities is relatively dark, and it is easy to enter into the flour during the milling process, which affects the color and bran content of the flour and increases the black spots. It is indispensable for flour grinding machine to clean up wheat.

有句話叫做：劣幣驅逐良幣。便宜的設備占據人們的注意力和購買力，將質量好的設備擠出競爭市場。購買到了劣質的石磨面粉機的企業在生產面粉的時候，不僅會出現除雜、潤麥、研磨不徹底、成品率低、質量不達標的現象，產品不能進如市場也會給客戶造成很大的經濟損失。

There is a saying: bad money drives out good money. Cheap devices occupy people's attention and purchasing power, and push high-quality devices out of the competitive market. When purchasing inferior stone flour mill, the enterprises will not only remove impurities, moisten wheat, grind incompletely, yield low, quality substandard phenomenon, products can not enter the market, but also cause great economic losses to customers.
