South Africa cassava starch processing plant

Sweet potato starch production line introduction:

Sweet potato starch is a kind of white powder of cassava that is dehydrated and dried after starch extracion. It is widely used in food industry and non-food industry. Sweet potato strach productionis a very promising market.

Sweet potato starch production line process:
Doing company mainly engaged in the design, processing and manufacturing of the Sweet potato starch equipment, and make installation and commissioning for the supporting projects.
Technical process of this sweet potato starch production line:
Fresh sweet potato - Cassava cleaning and washing - Grinding - Starch extraction -  Filtering and desanding - Starch concentration and purification - Dewatering - Drying
Machine order of this sweet potato starch production line:
Dry sieve - Paddle washer - Cutting machine - Rasper - Centrifuge sieve - Fine fiber sieve - Disc separator - Hydrocyclone - Vacuum filter  - Flash dryer

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 cassavas.
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 potatos into small pieces, 3-5cm, for further processing.
Rasper: Break the materials, crush cassavas 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 syetem, which will prevent starch gelatinization. Final starch water content is 12%-14%.
