Abstract
An apparatus and method for separating particulate solids from a liquid suspension relies upon a hydrocyclone having two radially and vertically spaced inlets in the upper portion thereof for establishing throughout the hydrocyclone concentric flow patterns of a fluid stream containing the particulate solids and a stream of wash fluid which are separately fed into the hydrocyclone through the inlets. The particles are efficiently separated and washed by passing laterally from one stream to the other as a result of inherent centrifugal or centripedal forces. Multiple hydrocyclone units arranged in a countercurrent series achieve a high product recovery per unit ratio. The invention is particularly suitable for freeze concentration of high value food products.
