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、初清小麥進入毛麥倉之前的清洗整個過程稱作初清。初清少應依據一道風篩結合的初清篩。初清的日常任務是小麥中的大沉渣(秸桿、稻穗、細細麻繩、木材等)和一部分輕而小的沉渣，以避免 大沉渣堵塞機械設備的國際貿易或運送管道，和避免 灰塵四處飄舞。小麥進入毛麥倉前，應設置一道自動式秤，有利于馬上把握小麥的類型、數量，有計劃方案地進倉和為小麥搭配提供依據。

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、毛麥清洗從毛麥倉到水分調節正中間的清洗整個過程稱作毛麥清洗。毛麥清洗的日常任務是提取小麥中的各式各樣沉渣，使保證入磨凈麥含雜標準以下。一般采用選擇、去石、洗麥、打麥、甄選和礦山機械設備。在毛麥清洗階段一般采用擦麥機或立式花鐵篩打麥機進行輕打，避免 導致過多的碎麥。

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、水分調節在有規范的制粉廠，應按小麥的制作工藝特點分類進行水分調節，并且在入磨前進行一次噴霧機著水，以得到非常好的制粉預期效果。只在入磨前適度著水，濕冷麥粒表面。升溫水分調節，一般說可以 降低潤麥時間，對軟質小麥的全麥面粉品質大大提高，因此在一般情況下不宜采用.

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、凈麥處理小麥在水分調節后一皮磨正中間的清洗整個過程稱作凈麥處理。它是為了更好地能夠更好地確保入磨凈麥質量，提高產品純度，對小麥進一步清洗的整個過程。凈麥處理重要采用打、篩、刷(均結合風選機)等機械設備。打麥可采用立式花鐵篩打麥機適當重打。刷麥能進一步對麥粒表面進行清洗，降低灰分。為保證帶磁沉渣提取的效率高，在小麥入磨前的一道選礦設備應取用永磁滾筒。

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.
