Buckwheat mill or buckwheat kernel and flour processing plant introduction:
Buckwheat mill refers to the whole buckwheat flour processing plant here. Whole buckwheat flour processing plant can produce buckwheat kernels and buckwheat flour. It includes cleaning, grading, peeling, rice processing, milling and packaging.

 
Buckwheat mill, or whole buckwheat flour processing plant technology:
A. Cleaning section: before buckwheat processing, we need to clean stones, dust, sand and other impurities. The cleaning technology: twice cleaning, twice destoning, once magnetic separation, and auxiliary wind power dedusting. 
The detailed cleaning procedures: 
bucket elevator-efficient vibrating sifter and vertical air suction duct- magnetic separator- gravity destoner- bucket elevator- flat rotary sieve- destoner- net buckwheat
 

B. Hulling and kernel processing:
Buckwheat material enters into double-bin plansifter by elevator and is classified into 6 grades. Each grade of material enters into respective buckwheat hulling machine which can hull the buckwheat and clean the buckwheat surface dust and microorganism meanwhile. After hulling section, buckwheat enters into 3 sets of double-bin plansifters for classifying. 
Color sorting technology: twice color sorting: color sorter separates and selects buckwheat rice by color difference to improve products purity. After color sorting section, the buckwheat rice can be directly packaged as end products, or enters into milling section for flour milling.
 

C. Flour milling section: buckwheat kernels and smashed buckwheat kernels can enter into milling section and be grinded by fine powder grinder to produce buckwheat flour. There are 4-5 stock bins, which can prepare grain flour products with different nutrition-allocated proportions.

D. End products and by-products packaging:
Different packing methods for end products and by-products: buckwheat rice and buckwheat flour adopts electronic quantitative packing machine to package due to large yield, while impurities and dust adopts machinery packing cabinet to package considering from the yield and products features. 
 

Technological design introduction for pneumatic transmission and dust removal by ventilation:
Fine powder and light sundries adopt sealing negative pressure wind transmission. High pressure blower is equipped with new TY series, and medium and low pressure blower adopts 4-72 series. Dedusting system and the high pressure wind net are both equipped with new type of pulse dust collectors.

Processing capacity: 20t- 500t
Raw grain moisture ≤ 14%
End products quality index:
A. Buckwheat rice yield rate≥ 60%
B. Buckwheat flour yield rate≥70%
1. Granularity: 100 mesh
2. Sand content: ≤0.02
3. Magnetism metals g/kg≤0.003
4. Moisture%≤13.5%
