Sweet potato starch is mainly stored in the fleshy part of the root, the raw material particles are relatively large, the internal organization is not

easy to destroy, the use of repeated file grinding, fully destroy the potato block structure, can make the small starch particles can be successfully

free from the root, improve the extraction rate of starch.

Main technical parameters

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.

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.



There are four steps to making sweet potato starch

1.Cleaning:To remove the stone sand and from the raw material .

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.
