The reslurry collector

Sometimes it is necessary to reslurry the cake discharged from the decanter. This is generally for washing out contaminants from the cake, as in lactose production. It is sometimes done in effluent thickening, and when a greater dryness than is required is produced by the decanter for easy control. Then the cake is back mixed with a feed by-pass which reduces overall flocculant consumption, because the by-pass does not need flocculant. The by-passing material is, of course, 100% recovery. 

The CIP feature is a very useful and necessary option for the decanter. It is used in many processes using foodstuffs, pharmaceuticals and biochemical products. To be able to clean a decanter to high levels of hygiene standard, without the need for dismantling, allows the use of decanters when otherwise it would be impossible. 

Extra high pressure units (200-350 bar) have recently been developed, which enable reduced sizes and costs for the same duty. Naturally, maintenance requirements are those normally associated with hydraulic
