Cassava Starch

Introduction

A premier technology providing institution for indeginously developed technologies is offering technology for cassava starch. Cassava starch is produced by wet-milling of fresh cassava tubers and dry cassava chips. Cassava is a rich source of starch while about 25 percent starch may be realised from mature and good quality tubers, about 60 percent starch may be obtained from dry cassava chips and about 10 percent dry pulp may be realised from cassava roots. Fresh tubers are processed during season and dry chips during the off season.

Process

Fresh cassava roots are washed to remove foreign matters and peeled mechanically. Then it is fed into raspers along with water for pulping, followed by filtration to separate starch so released during pulping. The residue is finely ground in plate mills to release residual starch from the pulp. It is then filtered in a multistage fibre washing system to recover starch from the pulp. The stream containing starch is put through centrifugal separators or the tabling system to eliminate fine fibre from starch. The starch is filtered/ centrifuged and finally the starch cake is dried in a flash dryer, packed for marketing. The residual cassava pulp is dewatered in a screen press, dried in a flash dryer and sold as animal feed.
