Sieving Potato Starch


A continental potato starch manufacturer required a sieve to check screen product through a single deck machine to remove oversize material. Inlet and outlet positions were out of line by approx. 1500 mm.


The product was fed directly from a spray dryer and discharged into existing gravity type pipework.


A Sievmaster Segregator Linear screener was selected as it allowed the product to be introduced directly from the feed pipe, and because of its conveying property it discharged almost exactly at the required offset discharge position.

A special arrangement was designed to provide the exact location positions. The enclosed machines were fitted with vision ports to allow mesh condition inspection and a panwork lifting arrangement to allow a one man dismantling facility. The top gallery was fitted with an adjustable weir plate arrangement to allow for adjustment of flow rate across the mesh screen.


The machine avoided the need for additional conveying from discharge to the next process and suited this type of process particularly well.

The client was very satisfied with this solution and an additional machine was later supplied.
