15-50kg/h Drum Type Roaster

The Unison Mini Roaster is a compact and cost-effective roasting solution designed for startups and small-scale food producers. Ideal for roasting peanuts, beans, nuts and seeds, it delivers uniform heating, consistent results and clean, natural flavor—making it an excellent choice for new businesses entering the roasting market.

Product Description

The Unison Nut Roasting Machine is designed for efficient drying and roasting of a wide variety of granular food products, including peanuts, broad beans, coffee beans, sunflower seeds, mixed nuts and more.

The machine combines a continuously rotating drum with infrared radiation and hot-air convection to provide fast, uniform and energy-efficient heating. Electric heating elements or gas burners supply heat indirectly, helping prevent localized overheating, burning and scorching.

Continuous material movement inside the drum ensures consistent roasting results while preserving the natural flavor, aroma and quality of the finished product.

Working Principle

During operation, the roasting drum rotates continuously, gently tumbling and mixing the material to ensure even heat distribution.

Heat is transferred through infrared radiation and hot-air convection rather than direct contact with the drum. This indirect heating method minimizes hot spots, reduces energy loss and delivers consistent product quality from batch to batch.

The automatic temperature control system provides an adjustable operating range of 0–300°C. A manual clutch allows the operator to discharge the product safely in the event of a power failure.
