1.Description of rasper
Key Technology & Innovation Potions
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. 

Structure introduction
Complete machine consists of rotor, rasping blade, engine base, upper cover, side cover, bearing base, gearing, motor, etc. 
1. Engine base props up all components, which rotor and bearings are all fixed on. 
2. Rotor is made of special stainless steel, uniform grooves on the surface to install saw blade. 
3. Saw blade is comprised of 2 stainless-steel layer with locating pin and a saw blade. 
4. Combined rasping blade are equipped on both side of rotor, which could achieve rotor two-way rotating and crests higher
crushing rate. 
5. A sieve is equipped between rasping blades, which is tensioned by two sets tensioning instruments. 

Main technical parameters
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.
