Mechanized production of sweet potato starch

Mechanized production processes: transportation, cleaning, crushing, screening, sand removing, precipitation (or concentration), dehydration, drying and air cooling packaging.This processing finished by Sweet starch production line.
 
1, the basic principles of cleaning:
Cleaning effect: mainly in the removal of sweet potato cortex stained with mud, wash and remove the sweet potato root epidermis.Cleaning the fresh sweet potato or sweet potato dry slice is the basis for ensuring the quality of starch, the more clean, quality of starch is better.
2, the basic principle of broken solution
Breaking role: sweet potato starch mainly stored in the root pulp, only a small amount of storage in endothelial cells. The purpose is to destroy the broken structure of sweet potato starch, the tiny particles can be successfully isolated from root of disintegration.
3, the basic principles of screening
Sweet potato residue is a slender fiber volume greater than the starch particles, expansion coefficient is greater than the proportion of starch granules, and light in starch granules, the breaking of the puree, with water as the medium, the potato residue containing starch further filtered water.
4, the basic principles of purification and precipitation
Mud and sand is greater than the proportion of water is greater than the proportion of starch granules, according to the principle of proportion of separation, using cyclone sand, or use the chute sedimentation method can achieve the ideal effect
5, the basic principle of dehydration
After the concentration of starch slurry still contains more moisture, further dehydration to dry.
6, the basic principle of drying
Air drying starch plant (also called flash drying) commonly used the whole process time is done in an instant, so moisture not gelatinization of starch granules has been dry, so it won't happen pasting or degradation phenomenon.
