Cassava Processing Machine

First the new harvest cassava will be stored in processing plant in clean concrete in the bunker. From there cassava will be carried by belt conveyor to the cleaning rotating drum. After cleaning the cassava is sent to the cleaning/peeling machine, and in cleaning/peeling machine with clean water to make up for the loss and sewage. Water comes out of the cleaning/peeling machine flows through a rotating sieve to remove potato skins and rough grain, and then pump into a hydrocyclone desander to remove the sand cassava brings.

After purification the water is pumped into the cleaning/peeling machine. The rotating sieve will expel the isolated cassava skins and other fiber. Cassava will be transported to a check belt conveyor to check the stone stocked in cassava or the damage caused by the parasite when comes out of cleaning/peeling machine, this machine will cut them into pieces. Because the cutting machine is located above the feed hopper of the flour grinding machine, the cassava pieces will be collected in the hopper. Cassava pieces will be feed into the milling machine from the hopper by a spiral whose speed is adjustable.

Shredded cassava pieces are feed into the cassava flour milling machine. Feed screw conveyor and hopper are connected to the bottom. The production of production line is controlled by feeding conveyor. When comes out from the grinding machine, crude cassava starch will moves into sand eliminating unit to the removal of emulsion sand and other coarse particles. The crude starch emulsion was sent to extract unit after sand eliminating. Crude starch is feed into nozzle separator emulsion through a precise sift. Crude starch is concentrated emulsion will be continuously discharged from the nozzle.

At the same time the cleaning water will be feed in the nozzle, because the concentration and cleaning are combined, and the combination of most of the impurities such as protein, latex and other from starch soluble substance of separation of overflow way to leave separator. Concentrated cassava starch after emulsion will be feeding directly into washing purification unit by a slurry pump. Washing purification unit is a multi-stage hydrocyclone unit, including washing purification and recycling. Starch is counter current rinse, protein content will be reduced to the required levels and remove fine fiber and other impurities.

The overflow of the part from washing flows into the recovery of recycling the remnants of starch. The isolated fiber is pumped into fiber dehydration unit for further dehydration. The starch percolate is recycled by a rotary flow unit and feed into the recovery of starch collecting cans. After starch emulsion mechanical dehydration, starch blocks are sent to the air dryer entry to dry into commodities level national starch by belt conveyor. Wet starch will be sent to the product feed hopper, and from there move into dry the heat flow in the pipeline. Starch is heat flow heating, water evaporated. After drying, starch through a set of cyclone separator and air separation.
