Abstract
Method and apparatus for separating and washing solid particles in suspension in a liquid which includes a series of continuously decanting centrifuges and an equal number of reslurry stations. Fresh wash liquid is introduced into the last of the reslurry stations, together with solids which are discharged from the next to last decanting centrifuge. Solids are separated from liquid in the last decanting centrifuge and the effluent therefrom is directed into the next to last reslurry station for dilution of the suspension therein. The system is particularly adapted for use as a continuous lautering method for producing malt beverages.
