Wet Spent Grain (WSG) is one of the largest by-products of beer and ethanol production
— rich in protein and fiber, but extremely difficult to preserve. 
Most breweries face the same issues with spent grain:
▪ High moisture = fast spoilage
▪ Seasonal overproduction
▪ Transportation challenges
▪ High drying costs with conventional systems
With the ExergyPSSD®, wet spent grain can be converted into a shelf-stable, high-value feed ingredient with:
▪ Uniform & predictable drying
▪ No oxidation or nutrient losses
▪ No VOC emissions
▪ Zero fire/explosion risk
▪ Minimal environmental impact
▪ Up to 80% heat recovery
Better feed quality, lower operating costs, and a more sustainable value chain — from brewery to farm.
