Belt Type Roasting and Drying Machine

Product Description

The Unison Belt Type Roaster is a high-capacity continuous roasting system designed for efficient roasting and cooling of peanuts, almonds, cashews, cocoa beans, seeds and other granular food products.

Available with electric, gas or diesel heating, the machine integrates roasting and cooling into one continuous production line. Its powerful hot-air circulation system distributes heat evenly throughout the roasting chamber, helping achieve consistent color, flavor and product quality while improving energy efficiency.

After roasting, the product moves directly into the integrated cooling section, where its temperature is rapidly reduced. This continuous process minimizes handling time and prepares the material for subsequent operations such as peeling, seasoning, grinding or packaging.

Working Principle

Raw materials are automatically transferred into the feeding hopper by a Z-type elevator and distributed evenly across the conveyor.

As the conveyor moves through the roasting chamber, circulating hot air passes uniformly through the material layer to provide consistent and controlled roasting. Conveyor speed and roasting temperature can be adjusted according to the product type, moisture content and desired roasting level.

The roasted product then enters the cooling zone, where forced air quickly removes residual heat. Finally, the cooled material is discharged continuously for the next processing stage.

Key Advantages

• Uniform Roasting: Controlled temperature and airflow ensure consistent color, flavor and moisture.

• Continuous Production: Uninterrupted operation increases capacity and reduces processing time.

• Energy Efficiency: Optimized hot-air circulation and optional heat recovery lower energy consumption.

• Automated Operation: Adjustable temperature, airflow and conveyor speed reduce labor requirements.

• Integrated Cooling: Rapid cooling prevents over-roasting and prepares products for further processing.

Applications

Suitable for roasting and drying:

• Peanuts

• Broad beans

• Coffee beans

• Sunflower seeds

• Mixed nuts

• Other beans, seeds and granular food products
