Cassava starch processing machine is mainly used for extract starch from cassava. These machines firstly clean the attached debris of cassava, then grate cassava into pulp, and then separate fibers, protein and other impurities in cassava pulp to get pure starch, and finally dewater and dry starch to get desired quality cassava starch.

Cassava starch processing machine is mainly used for extract starch from cassava.
These machines firstly clean the attached debris of cassava, then grate cassava into
pulp, and then separate fibers, protein and other impurities in cassava pulp to get
pure starch, and finally dewater and dry starch to get desired quality cassava starch.
The complete set of cassava starch processing machine includes dry sieve, paddle
washer, cutting machine, rasper, centrifuge sieve, fine fiber sieve, desander,
hydrocyclone station, peeler centrifuge and flash dryer.
Cassava starch processing line
Here are the introduction of cassava starch processing machine and their functions:
(1) Dry sieve:
Function: To clean cassava. Dry sieve is firstly used to remove impurities from
harvest cassava tubers, like stems and leafs, dirt, sand, weeds, stones, roots on
cassava tubers surface. During dry sieve working, no water is needed. And add this
cassava starch processing machine as the first stage of cassava cleaning can save
water consume in cassava processing plant.

(2) Paddle washer:
Function: To further wash cassava. After cleaning, the paddle washer is adopted to
remove mud, peel and other impurities from cassava tubers, and water is required.
This cassava starch processing machine adopts countercurrent washing principle, by
the effect of paddle rotating, cassava tubers flows in the converse direction against
water, which makes washing completely and eliminate sand and mud effectively.

(3) Cutting machine:
Function: To cut cassava tubers into small pieces. Cassava tubers usually large and
irregular in shape. Therefore, in the production process of the cassava starch
processing machine, the cassava tubers should be cut into small pieces with the
cutting machine, and then for further crushing, which can not only reduce the
pressure of the rasper, but also is conducive to the full crushing of cassava.

(4) Rasper:
Function: For fully crushing. Rasper is a high efficient cassava grater which can fully
destroy the cassava structure, so that the tiny starch granules can be disintegrated
and separated from the cassava tubers. With water as medium, this cassava starch
processing machine can fully crush cassava into pulp by relying on high-speed
rotating. This is the most advanced cassava grater whose crushing rate is more than
94%. And the grated starch slurry can passes through the 1.2-1.4 mm mesh.

6. (5) Centrifuge sieve & Fine fiber sieve:
Function: To separate fibers from starch slurry. The crushed starch slurry need to be
sieved in this step to separate fibers from starch slurry. The large fibers are removed
by using centrifugal sieve and fine fibers are further removed by fine fiber sieve.
These two cassava starch processing machines are mainly to achieve the purpose of
separating and purifying of the starch. Multiple separation and countercurrent
washing processes are commonly employed, and after separation, the fiber
impurities content of the starch slurry is less than 0.05%.
Centrifuge sieve
(6) Desander:
Function: To remove sand in starch slurry to improve starch taste. According to the
principle of gravity separation, the starch slurry is pumped into the cyclone by a
pressure pump, where the bottom stream removes sand while starch slurry flows
through the top to achieve the purpose of sand removal.

7. Desander
(7) Hydrocyclone:
Function: To wash, concentrate and refine starch slurry. The adopted cassava starch
processing machine in this step is hydrocyclone system, which mainly separates the
insoluble protein and residual soluble protein and other impurities so that the
obtained starch slurry is pure. It separates impurities by taking using of the different
specific gravity of water, starch and yellow pulp protein. DOING uses a 12-stage
hydrocyclone systemto achieve the function of washing, refining and concentrating
of starch slurry. The produced liquid after this process is called starch milk, which is
pure and white.

8. Hydrocyclone station
(8) Peeler centrifuge:
Function: To dewater starch milk to faciliate drying. The starch millk is dewatered to
achieve the required moisture content (less than 40%) for drying, and the water
content of the cassava starch can reach 36.5% after dewatering by DOING peeler
centrifuge.

9. Peeler centrifuge
(9) Flash dryer:
Function: To dry starch to meet international standard. The wet material enters the
drying pipe from the powder feeding machine, where it will mix with the heated high
speed fresh air. In the drying pipe of the cassava starch processing machine, the high
speed hot air will dry starch to required moisture by heat exchange. And the
produced cassava starch moisture content is 10%-14%.

DOING cassava starch processing machine features:
Doing Company manufactured complete cassava starch processing machine can
automatically complete the whole process of cleaning, crushing, separation,
purification, concentration and refining, dewater, drying and packaging. The
production line has the following characteristics:
(1) High automatic degree, these machines can automaticlly complete the entire
production process from cassava tubers into cleaning to finished dry starch
production, the labor intensity is small.
(2) The material of the cassava starch processing machine is mainly made of stainless
steel to ensure a hygiene environment and prevent starch from pollution.
(3) High yield and high quality, adopts international processing technology and
equipment, starch extraction rate is high, starch yield is high, and meanwhile the
finished dry starch has higher quality.
(4) Short processing time, processing from cassava tubers into starch just 10-15
minutes.
