Processing Distillers Mash & Spent Grains

Separating liquid solubles from spent grains during liquor or spirits production to reduce disposal costs and operator handling

The production of alcohol such as gin, vodka and whiskey in the craft distillery industry requires the mash to be processed either before or after the still to remove as much liquid as possible. Until now this process, known as dewatering spent grains or processing spent mash, has been a time consuming and costly operation. Installing the Russell Liquid Solid Separator™ at the end of your process provides a cost effective solution for continuous separation of spent distillers grains from the liquid.
