cassava starch manufacturing process
Cleaning and washing processThe purpose of cleaning in cassava starch production line is to remove sand, soil and peel which can not only reduce starch ash content but also be good for the next processing procedure. During the time of transportation, the cleaning is carried out, so the feeding should be even. If there is too much cassava in the cage, there will be no space for cassava to roll, needless to say to achieve the purpose of cleaning. While too little will waste space and influence the output.
Grating process
The cleaned cassava is pulverized by a rasper, and the function of grating for cassava starch manufacturing process is to destroy the structure of cassava, so as to make sure the tiny starch granules can be disintegrated and separated from the cassava cells.
Cassava grating machine
Screening processPhysical separation is adopted in cassava starch manufacturing process for the separation of starch residue from slurry. By utilizing high speed centrifugal force, DOING centrifuge sieve can effectively remove the fibers from slurry. Automatic front and back washing system of the cassava starch processing machine is equipped to ensure the mesh penetration.
Desanding process
Even after many centrifuge process, the starch slurry still contains some small fiber and other impurities. The sand in the cassava slurry needs to be removed by the desander.
Refining process
Another key operation in cassava starch manufacturing process which will influence the starch extraction. Hydrocyclone station is used for removing soluble protein, insoluble protein and other impurities of starch slurry. 18 stage hydrocyclone in series is adopted to realize the washing, recovering and refining of starch milk.
Cassava starch drying machine
Dewatering & drying processThe next step of cassava starch manufacturing process is the dewatering. The dewatering machine in Doing Company is the peeler centrifuge. This touch material is made of high quality stainless steel which ensures high starch quality. After dewatering, the starch will be dried in the flash dryer machine. Within 2-3 seconds, the hot air will vaporize the water through high and let it out through the separator.
