High volume rotary dryer roaster for continuous drying

Achieve uniform drying and roasting with a continuous, high-capacity rotary system designed for precise temperature control and optimized air management, perfect for ensuring product consistency and quality across a diverse range of solid and granular snacks.

Dries and Roasts High-Volume Snack Products

The Rotary Dryer Roaster from Heat and Control offers a continuous, multi-zone convection system designed for precise drying and roasting of a variety of snack and food products. Utilizing a smart, step-spiral, and flighted drum design, it ensures first-in, first-out production, delivering even heating and optimal product uniformity. Ideal for processing nuts, dough-coated nuts, seeds, and protein-based snacks, this equipment offers customizable processing zones that independently control temperature and airflow, enhancing product characteristics and quality.

With the capability to handle high-volume operations, the Rotary Dryer Roaster integrates seamlessly into production lines, utilizing energy-efficient, product-focused heating to maximize heat transfer while minimizing loss. Constructed from full stainless steel, it features a food safety-focused design that includes an optional Clean-In-Place (CIP) system for streamlined sanitation and maintenance, maintaining compliance with stringent AMI guidelines. The PLC-controlled system further enhances automation, allowing remote monitoring and adjustment for optimal operation.
