System and method for filtering beverages
Last updated:
Abstract:
A method for preparing a filtered beverage includes filtering a raw beverage using a cross-flow ultrafiltration device to produce a solids fraction and a liquid fraction; heating the solids fraction to a temperature of 60.degree. C. or greater to produce a pasteurized solids fraction; microfiltering the liquid fraction through a microfilter having a size cut-off of 1 .mu.m or smaller to produce a microfiltered liquid fraction; and combining the pasteurized solids fraction and the microfiltered liquid fraction to result in the filtered beverage.
