Cassava starch is mainly stored in the fleshy part of root tuber, the raw material particles are relatively large, the internal tissue is not easy to destroy, the use of repeated file grinding, fully destroy the structure of potato block, can make the small starch particles can be successfully free from the root tuber, improve the rate of starch extraction.

Advantages of rasper
1. All parts in contact with raw material are made of food-grade stainless steel, which protects materials from outer pollution.
2. High rotating speed, high line speed, excellent rasping performance, uniform particle, and high starch ionization rate. 
3. Rotor is calibrated with international advanced dynamic-balance instrument, meeting G1 standard. 
4. Components(bearings for example) are imported from Europe with longer service life
5. Unique sieve-tension gear makes disassembly easy. 
6. Saw Blade is manufactured with special steel by special process, with higher hardness and wear resistance. 
7. Rasping bulk is cast of high-chromium iron, hardness reaching HRC60, having excellent wear resistance. 
8. Unique drum groove and layering instrument design benefits saw blade changing.

The working principle of rasper
The material enters into the body of the file mill shell through the upper entrance, and is broken by the impact, shear and grinding effect of the saw blade moving at high speed. The lower part of the rotor is equipped with a screen screen. The material smaller than the size of the screen hole is discharged through the screen plate, and the particles larger than the size of the screen hole are blocked and remain on the screen plate to continue to be hit and grinder by the saw blade.

Real application case

There are four steps to making cassava starch
1.Cleaning:To remove the stone sand and from the raw material ,and peel it.
2.Crushing :To destroys the fiber structure and makes the starch particles free.
3.Separator:To removing sand ,mud from starch slurry, degreasing, microslag separation, protein separation, washing and concentration of all kinds of starch and modified starch emulsion.
4.Drying and Packing:To dehydrator the wet starch, sifter and packaged.
