Industrial malt roaster for specialty malts
Roasting malt and barley to achieve particular flavors and quality is a critical process in the production of specialty malts. Uniform heat distribution and precise control are essential to avoid quality inconsistencies and inefficiencies.
Achieve consistent roasting quality
The Industrial Malt Roaster FRD M, developed by Hamburg Dresdner Maschinenfabriken GmbH, is designed for processing both green and dry malt and barley. This batch roaster features an external heating oven that ensures even heat distribution along the entire drum, preventing hot-spots and guaranteeing a homogeneous roast. The drum gently mixes the grains, allowing for even roasting, even with high moisture content. The roaster includes a front gate with axial movement on a railway system to avoid jamming and wear. The inner gate disc is driven continuously by the rotating drum, ensuring no transmission slip or wear during discharge. The rear of the drum is cast in a round design without spokes, thus preventing product deposits. An additional standalone bacteria filter ensures product safety. The roaster’s batch sizes range from 1800 to 3500 kg for crystal malt and 2000 to 4000 kg for roast malt, depending on bulk density, making it suitable for various production scales.
