CRD Continuous Roaster Drum

The PROBAT CRD Continuous Roaster Drum is designed for the precise and continuous roasting of almonds, hazelnuts, peanuts, pumpkin seeds, and sunflower seeds. Thanks to its advanced convective roasting technology, the CRD achieves highly uniform color and flavor formation while minimizing product breakage, fat migration, and thermal stress.

The product is continuously transported through a slowly revolving, non-perforated roasting drum by an integrated spiral screw. Inside the drum, small product batches move gently through individually controlled roasting zones, allowing precise control of roasting time and temperature. Rather than relying on direct contact heat, the CRD uses forced and graded convective heat, creating a fluidization effect that slightly lifts the product and ensures that every surface is exposed evenly to the roasting air.  

The non-perforated drum design further reduces mechanical stress, prevent clogging and product adhesion, and contributes to minimal maintenance requirements and reliable operation.

The optional integration of the Humidity Monitoring Cockpit advances humidity and moisture control for an optimized Maillard reaction, unlocking deep, complex flavors that enhance product quality.
