Brewer's spent grain drying stabilises the malted barley husks and protein left after mashing, the largest by-product of any brewery. Wet BSG spoils in two to three days, which limits it to nearby farms. Drying it opens markets for high-protein, high-fibre flour, feed and fuel, and gives breweries a reliable outlet.
To dry brewer's spent grain, GEM recommends the Band Dryer (Beltotherm) and Rotary Tube Bundle Dryer. Typical moisture is 75–80% in the feed and 8–10% after drying. Rotary Dryer and Mesh Belt Dryer are used when the feed or site calls for it. Every project starts with a pilot trial on your own sample.
A Beltotherm band dryer handles pressed BSG gently for food-grade flour, while a steam-tube rotary suits feed lines using brewery steam. Direct rotary dryers fit high-volume feed output; a mesh belt is economical for smaller craft breweries.
| Typical feed moisture | 75–80% |
| Typical target moisture | 8–10% |
| Recommended dryer | Band Dryer (Beltotherm), Rotary Tube Bundle Dryer |
| Alternatives | Rotary Dryer, Mesh Belt Dryer |
| Application area | Pomace, Pulp & By-products |
| Industries | Animal Feed, Breweries & Distilleries, Food & Beverage |
Drying replaces daily wet removal with a product that keeps for months and can be sold well beyond the farm radius. Food-grade BSG flour achieves a higher price than wet feed sold locally.
Plants searching for a brewers spent grain dryer or comparing a BSG drying machine usually need three answers: which dryer fits, what it costs to run, and how fast it pays back. For Brewer's Spent Grain, we start from your throughput, current moisture (typically 75–80%) and the target (8–10%), trial a sample on the Band Dryer, and return a sized recommendation with a budget quotation for your animal feed and food operation.
