Abstract
Tilting filter pans having generally parallel leading and trailing sidewalls which are sloped at an angle to permit increased filtration rates for a predetermined filtering efficiency, and also to permit increased filtering efficiency where the feed rate is constant. Drainage of the pans may also be improved. The feed is a slurry from which the liquid is removed, and the filter cake is dumped by rotation of each filter pan at a predetermined point of movement of the filter pan along a cyclical path.
