The production of stone mill flour machinery and equipment factory cannot do without wheat cleaning. As the supporting equipment of stone mill equipment, wheat washing machine is mainly responsible for cleaning the micro impurities in wheat. Wheat washing machine is divided into two processes: washing and drying, which not only completes the cleaning of wheat grains, but also does not affect the subsequent flour processing. The whole process is harmful to the production of whole wheat flour and the quality and fineness of whole wheat flour in the second half of the period. The cleaning process of wheat is relatively long, which is generally composed of four stages: initial cleaning, cleaning of woolen wheat, water regulation and wheat cleaning.

1、初清小麦进入毛麦仓之前的清洗整个过程称作初清。初清少应依据一道风筛结合的初清筛。初清的日常任务是小麦中的大沉渣(秸杆、稻穗、细细麻绳、木材等)和一部分轻而小的沉渣，以避免 大沉渣堵塞机械设备的国际贸易或运送管道，和避免 灰尘四处飘舞。小麦进入毛麦仓前，应设置一道自动式秤，有利于马上把握小麦的类型、数量，有计划方案地进仓和为小麦搭配提供依据。

1. The whole process of cleaning the wheat before it enters the wheat bin is called preliminary cleaning. The initial cleaning should at least be based on a combination of air and screen. The daily task of the early Qing Dynasty was to remove the large sediment (straw, rice ear, fine hemp rope, wood, etc.) and some light and small sediment from wheat, so as to prevent the large sediment from blocking the international trade or transportation pipeline of machinery and equipment, and avoid dust flying everywhere. An automatic scale should be set up before wheat enters into the warehouse, which is helpful to grasp the type and quantity of wheat immediately, and provide the basis for wheat combination.

2、毛麦清洗从毛麦仓到水分调节正中间的清洗整个过程称作毛麦清洗。毛麦清洗的日常任务是提取小麦中的各式各样沉渣，使保证入磨净麦含杂标准以下。一般采用选择、去石、洗麦、打麦、甄选和矿山机械设备。在毛麦清洗阶段一般采用擦麦机或立式花铁筛打麦机进行轻打，避免 导致过多的碎麦。

2. The whole cleaning process from the wheat bin to the middle of water regulation is called wheat cleaning. The daily task of cleaning wheat is to extract all kinds of sediment in wheat, so as to ensure that the impurity content of wheat is below the standard. Generally, selection, stone removal, wheat washing, wheat beating, selection and mining machinery and equipment are used. In the cleaning stage of woolen wheat, the chafer or vertical iron screen thresher is generally used for light beating to avoid too much broken wheat.

3、水分调节在有规范的制粉厂，应按小麦的制作工艺特点分类进行水分调节，并且在入磨前进行一次喷雾机着水，以得到非常好的制粉预期效果。只在入磨前适度着水，湿冷麦粒表面。升温水分调节，一般说可以 降低润麦时间，对软质小麦的全麦面粉品质大大提高，因此在一般情况下不宜采用.

3, water regulation in a standardized milling plant should be classified according to the characteristics of the wheat production process for water regulation, and before grinding into a spray machine to water, in order to get very good expected effect of pulverizing. The surface of wheat grain should be wet and cold before grinding. Generally speaking, temperature and water regulation can reduce the moistening time and greatly improve the quality of whole wheat flour of soft wheat

4、净麦处理小麦在水分调节后一皮磨正中间的清洗整个过程称作净麦处理。它是为了更好地能够更好地确保入磨净麦质量，提高产品纯度，对小麦进一步清洗的整个过程。净麦处理重要采用打、筛、刷(均结合风选机)等机械设备。打麦可采用立式花铁筛打麦机适当重打。刷麦能进一步对麦粒表面进行清洗，降低灰分。为保证带磁沉渣提取的效率高，在小麦入磨前的一道选矿设备应取用永磁滚筒。

4. The whole process of wheat cleaning after water regulation to the middle of a skin mill is called wheat cleaning. It is to better ensure the quality of milled wheat, improve the purity of products, and further clean the whole process of wheat. Threshing, sieving, brushing (all combined with air separator) and other mechanical equipment are used for wheat cleaning. The vertical iron screen threshing machine can be used for threshing. Wheat brushing can further clean the surface of wheat grain and reduce ash content. In order to ensure the high efficiency of magnetic sediment extraction, the permanent magnetic drum should be used in a beneficiation equipment before wheat grinding.
