How to extract starch in cassava starch production line

starch centrifugal sieves machine
Starch extraction is finished by starch centrifugal sieves machine.
It is not a easy job to get the starch grain of about 20μm from the roots pulp which mixed with roots fibers, liquid of protien, minials, etc. To sieve off the bigger size of roots fibers obviously comes to be the first step to get the starch grain. Either by plane rotating sieve screen or round rotating sieve screen, obviously sieve screen becomes the key issue. The mesh size of the screen must be choosed properly, and it also should be strong enough, and most importantly we should keep it unblocked as its hole size from 120μm to about 80μm which is easily being impeded. In this process, spray washing is an important way to keep the sieve hole continuously open both by process water and clean water. And the amount of them should be counted accurately to keep the whole flow balance run.
