Main equipments and its function in this sweet potato starch production line:
1) Cleaning parts of sweet potato starch production line:
Dry
sieve: Widely used in impurities pre-removal for starch production.
It's used to remove dirt, sand, small stones, weeds and other impurities
that are attached on the surface of potato, sweet potato and sweet
potatos.
Paddle washer: Mainly used to wash the raw materials.
Adopted countercurrent washing principle. By the effect of paddle
pushing, the raw material flows in the converse direction against water
currently, which makes washing completely and eliminate sand and mud at
most.
2) Crushing parts of sweet potato starch production line:
Cutting machine: Its main function is cut sweet potatos into small pieces, 3-5cm, for further processing.
Rasper:
Break the materials, crush sweet potatos into slurry, release starch
particles from cell, with high starch dissociation rate.
3) Starch extraction of sweet potato starch production line:
Centrifuge
sieve: Used for the extraction of starch from the materials, remove
fiber from starch slurry, high starch extraction rate.
4) Starch filtering and desanding of sweet potato starch production line:
Fine
fiber sieve: It is a machine mainly for separating small particles of
fiber from starch slurry. This process is achieved by gravity of the
slurry and screen mesh inside the drum.
5) Starch concentration and purification of sweet potato starch production line:
Disc
separator: It is widely used in processing of starch to separate
protein and cell liquid out of slurry, with high separating factor.
Hydrocyclone:
It is designed to get rid of related substances such as fiber and
protein in the starch milk. For the starch's washing, concentration and
purification.
Usually suggest this two machine used in combination, make the production high efficiency and high quality.
6) Drying system of sweet potato starch production line:
Vacuum filter: Widely used for the starch dewatering, final starch water content is 38%-42%.
Flash
dryer: This is the last step for potato starch production. It adopts
low temperature drying system, which will prevent starch gelatinization.
Final starch water content is 12%-14%.
Above all, its the complete sweet potato starch production line.
