Liquid is drained from the cake (46) in the beach section of a centrifuge bowl (40) by providing a dedicated flow path or a series or flow paths from the beach section. The flow path or paths are designated to drain away expressed liquid while maintaining substantially the flow of cake up the beach to the cake discharge opening(s) irrespective of solid throughput. The expressed liquid is guided from the beach section back to the slurry pool (48) in the cylindrical section (38) of the centrifuge bowl. More specifically, one or more liquid guide channels may be provided in the beach area under the surface supporting the cake flow towards the cake discharge end of the centrifuge. The liquid guide channels may be established by providing a porous liner (50) along the beach section of the centrifuge bowl. Preferably, the liner extends down the beach at least to the level of the pool. |
