ABSTRACT:
An automatic apparatus for the continuous freeze concentration of liquids. The apparatus includes a heat exchanger for freezing the liquid to form a slurry of ice crystals and concentrated liquid. Communicating with the heat exchanger via a line or pipe is at least one, and preferably two, separating and rinsing columns, connected in parallel, to which the slurry is pumped for separating the concentrated liquid from the ice and subsequently rinsing the ice to remove any residual liquid therefrom. First and second receptacles are provided for collecting the concentrated liquid and the ice from the columns, respectively.
