Sweet potato starch is a kind of white powder of sweet potato that is
dehydrated and dried after starch extraction. It is widely used in food
industry and non-food industry. Sweet potato starch production is a
very promising market. Doing company mainly engaged in the design,
processing and manufacturing of the sweet potato starch processing plant, and make installation and commissioning for the supporting projects.

Main equipments and its function in this sweet potato starch processing plant:
1) Cleaning parts of sweet potato starch processing plant:
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 potatoes.
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 processing plant:
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 processing plant:
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 processing plant:
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 processing plant:
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 processing plant:
Vacuum filter: Widely used for the starch dewatering, final starch water content is 38%-42%.
Flash
dryer: This is the last step for tapioca 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 processing plant.
