how to get starch from the cassava root

Cassava starch, a kind of white powder, which obtained from cassava root by dehydrating and drying cassava after starch extraction. Cassava starch has two major categories of native starch and various modified starches. Cassava starch is widely used in the various industries such as food, beverage, candy, chemical, paper, pharmaceutical, cosmetic and biodegradable materials,etc. 

How to get starch from the cassava root? The person in charge of Kaifeng Sida Agricultural Products Equipment Co., Ltd introduced:

All steps of the cassava starch extraction process, the roots of harvested plants must be delivered within 48 hours of processing Prevent deterioration. Kaifeng Sida cassava starch production line from the beginning feeding to the final starch drying timed out within 30minutes.

First washing, to get high quality starch, washing section is very important, Kaifeng Sida cassava starch production line adopts three step to ensure all cassava roots clean, first cassava roots come into drum washer to remove outside sand and impurities. Then come into U type cleaning machine, U type cleaning machine use soaking method to remove hollow sand, third, cassava roots come into roller cage with water spraying. After these three step, you will get cleaned cassava roots. Then go to next step- crushing and milling. In this section, grated root starch granules are released. In the "starch milk" ,the water contains suspended particles , centrifuged and then in the slurry, after which the particles are separated from the water by precipitation or at. At this point, the starch will come into de-watering machine to remove moisture, after De-watering machine, the moisture is about 38% to 42%, then the wet cassava starch come into drying machine. Kaifeng Sida air clash dryer is their National Invention Patent products, from wet starch come to dry starch out only few seconds. In this condition, he comprehensive extraction starch plant has a daily output from 10tons up to 150 tons.

All extraction systems produce a beneficial amount of residue. Root stripping can be recycled as fertilizer and animal feed. Once dry, the discarded fiber can be sold as a flocculant for the mining industry, while the low concentration of starch precipitated during the precipitation is used as a pig feed.
