Automatic cassava starch production plant
cassava starch production plant
Cassava Starch is produced by wet-milling of fresh . Starch is the
main constituent of cassava.
Our company is professional manufacture the automatic cassava
starch production plant . The whole automatic cassava starch
production plant is comprised of 13 units as below:
1. Raw material receiving unit
Material receiving unit is the first link of cassava starch
processing. The primary purpose of this unit is the cassava
preliminary removing impurity and the smooth storing in inside of
material storage tank.
Cassava is conveyed to the cassava yard after weighingby wagon
balance, and then is conveyed into the cassava storage hopper by
The key of this unit is to remove sand and other impurities of
cassava during the harvest, the sand stick to the cassava can drop
through the vibrating screen. Preliminary de-sanding and removing
impurity can relieve machine burden of de-stoning and cleaning
Attention must be taken that cassava should not be damaged in
cassava purchase. Damaged cassava is easily decayed, and decayed
cassava is vulnerable to infect around cassava. Bad cassava
material has a big influence to starch quality.
2. Raw material conveying unit
Cassava stored in the cassava hopper is conveyed to the large
inclination-angle belt conveyor through conveying belt at the
bottom of the hopper, and further is conveyed into cleaner to
remove impurities by the large inclination-angle belt conveyor,
removing sand and other impurities mixed in the materials at
3. De-stoning, cleaning and crushing unit
Clean raw materials for cassava processing play an important role,
so de-stoning and cleaning unit of pretreatment stage is the most
important. The purpose of this unit is to get rid of sandstone,
clay of cassava, and to deposit cleaned cassava in the cassava
Cassava is conveyed into the blades washer, blades washer adopts
counter-current cleaning principle. Water flow (used for washing)
and the materials movement direction is opposite. Certain level of
cleaning water is poured into the cleaning trough, cassava raw
materials almost float on the surface of water and move forward
along rolling blades through internal trough. The cassava rotates
and clashes each other in the water, getting rid of the soil and
impurities on the surface of them in the greatest degree. Heavier
sand and other heavy impurities sink to the bottom of the trough.
waste water outflows through the overflow outlet below the first
trough, discharged soil and impurities sink to the drain outlet,
and finally are discharged from there. In the end, the root pieces
(materials) are conveyed to the next production link, through
maximum cleaning of unloading fence.
Finally the cassava cleaned by the three-grade blades washer, fall
into the crusher through the big inclination-angle belt conveyor to
carry on the preliminary slicing of cassava tuber.
Cassava is cut into small piece to ensure rasping efficiency of
rasper. Cubage of raw material temporary storage bin generally is
designed to store washing quantity for one to two hours.
4. Rasping and pumping unit
Rasping unit is the most important link to influence cassava starch
extraction rate. Efficient rasper can release cassava starch
particles from cassava cells thoroughly, guaranteeing the
combination starch content of cassava residue to the minimum.
At the bottom of the temporary warehouse links a discharging outlet
of special design which connects a feeding spiral with adjustable
speed. Feeding spiral has three outlets, two rasper connectors and
one overflow outlet. A length of short connection with gate valve
is between rasper
