Centrifugal decanters are used for the separation of different grades of starch. There are many' problems associated with the use of these decanters such as high investment, maintenance and operation costs, and the necessity of employing
shock-absorbers. in the foundation.
Therefore, multi-cyclones were designed to
replace these decanters. The advantages of these multi-cyclones are lower costs,
absence of any moving parts, ease of
construction and the possibility of using different materials of construction. The drawback of these multi-cyclones is their lack of flexibility in coping with different operating conditions. Overall, good results were obtained from this substitution.
