Industrial rotary disc dryer with steam indirect heating for animal by-product processing

Overview

Our Rotary Disc Dryer is engineered for continuous, indirect steam drying of low-fat animal by-products, poultry waste, fishmeal, and hydrolyzed feathers. With a compact footprint and high heat transfer efficiency, this disc dryer ensures fast, uniform moisture removal while integrating cooking and drying into a single system. Designed for rendering plants and protein recovery operations, it delivers energy savings, reliable sterilization, and consistent throughput.

Key Features of Rotary Disc Dryer

  • Indirect Steam Heating

    Internal discs and hollow shafts ensure rapid and efficient evaporation.

  • Compact, Space-Saving Design

    Ideal for installations with limited space in rendering lines.

  • Continuous Cooking & Drying

    Streamlines production by combining thermal processes in one unit.

  • Customizable for Material Types

    Suitable for fish waste, poultry offal, feather meal, and other low-fat materials.

  • Low Maintenance

    Robust construction reduces downtime and operating costs.

Applications of Disc Dryer in Rendering Plants


  • Rotary disc dryer for hydrolyzed feather meal processing in poultry rendering plant

    1. Animal by-product processing (meat, offal, bones, viscera)

    2. Poultry waste drying (feathers, entrails, hatchery waste)

    3. Fishmeal production (whole fish, trimmings, seafood residues)

    4. Hydrolyzed feather meal drying

    5. Protein recovery lines in meat, poultry, and aquaculture sectors

Working Principle

Steam enters the rotating disc shafts and internal hollow tubes, creating a large heated surface area. Material moves through the chamber via paddle rotation, ensuring uniform exposure and consistent drying. The closed-loop design maintains product integrity and reduces environmental impact.
