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.
