Belt dryer ST-15

Belt dryers are used in production lines for dry pet food. The drying process takes place at temperatures ranging from 60°C to 110°C, while the product temperature at the dryer’s output does not exceed 40°C.

Belt dryers of the "ST-15" type are designed for both drying and cooling the product. During drying, warm air flows through the product from bottom to top, opposite to the movement of the transport belts, which allows for effective moisture removal. The moisture is then extracted by fans located on the upper wall of the dryer.

Goals of the drying process:

• Gentle and even removal of moisture from the product;
• Prevention of crust formation or cracks on the product's surface;
• Ensuring appropriate moisture levels, allowing for long-term storage.

This dryer can be part of a production line for dry pet food based on ESK series extruders. Its simple design, reliable operation, and versatility make tunnel drying popular worldwide. The standard dryer configuration does not include a heat exchanger or temperature blower, but upon customer request, we can equip the machine with these components to ensure stable and easy operation. To maintain sanitary standards, the air is heated exclusively by the heat exchanger, which eliminates contact between the food and harmful gases.

Features and characteristics of the dryer:

• Five ventilation exhausts for moisture removal and air recirculation;
• Five levels of transport (food-grade) belts, 15 meters long and 500 mm wide;
• Adjustable belt incline;
• Doors located at the ends and sides of the device for easy maintenance;
• Powered by a 2.2 kW gear motor;
• Adjustable legs for stable positioning on uneven floors.
