Abstract

1372281 Freeze concentrating solutions STRUTHERS SCIENTIFIC & INTERNATIONAL CORP 4 Jan 1973 [5 Jan 1972 (2)] 362/72 and 363/72 Heading BIG [Also in Division A2] An aqueous solution comprising coffee extract, tea, beer, or citrus fruit is concentrated by freezing the solution to form ice, feeding the concentrated solution and ice to a centrifuge wherein ice is separated from the concentrated solution with foam formation, separating the foam and converting the latter to a liquor which is included in the final concentrated product. Foam is recovered from the ice, concentrated liquid and the centrifuge. The foam is generally removed from the centrifuge with wash water from melted ice, fed to a liquid holding tank from where liquor is removed and again concentrated and the foam fed to a treatment vessel wherein the foam is either treated with steam or allowed to subside after 2 to 24 hours to a liquid. Foam associated with the concentrated liquid may be recovered in a treatment tank in a manner similar to that recovered from the centrifuge. Foam associated with the ice is recovered by feeding the ice and foam to a melting tank wherein the temperature of the tank is rapidly increased, e.g. by heating coils, and the foam converted to a liquor. The foam may also be recovered by freeze drying. The process may be carried out continuously and the Specification includes flow diagrams of such continuous processes.
