Abstract
Process for freeze-concentrating food liquids such as fruit juices, coffee extracts, beer and so forth, in which the substance to be treated is conveyed through a multi-stage freeze concentrator and is conveyed from the freeze concentrator stage with the highest concentration to a module in which the concentration, and thus the viscosity, is increased by crystallization, and a partial separation of mother liquor is obtained by means of a contrifuge.
Claims9
A process for freeze-concentrating food liquids without the loss of product or flavor, by conveyance through a multi-stage freeze concentrator comprising the steps of:
- concentrating a food liquid in a freeze concentrator;
- conveying said food liquid from said freeze concentrator to a module;
- increasing the concentration by crystallization of said food liquid in said module;
- and
- centrifuging the increased concentrated food liquid obtained from said module to partially separate a mother liquid, thereby yielding a food liquid with at least about a 50 wt. % concentration.
