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

Working Principle

The Disc Dryer operates on the principles of heat conduction and radiation. Inside a closed chamber under negative pressure, the material is continuously stirred and pushed forward by paddles mounted on the rotating discs. Steam flows through the hollow central shaft and double-arm discs, providing a large heating surface and powerful evaporation capacity. As the material moves from the feed inlet to the discharge outlet, moisture is gradually removed until it reaches the preset drying standard. This ensures uniform drying, consistent product quality, and safe operation.

Key Features & Benefits

  • Efficient Heat Transfer

    Large heating surface area ensures rapid and uniform drying.

  • Indirect Steam Heating

    Maintains material quality and avoids contamination.

  • Sterilization and Disinfection

    High-temperature drying effectively eliminates bacteria, viruses, and parasites.

  • Resource Recovery

    Valuable components such as protein, fat, and collagen can be reclaimed for use in feed, fertilizer, or industrial products.

  • Environmental Protection

    Reduces organic waste pollution, minimizes odors, and lowers the risk of disease transmission.

  • Customizable Solutions

    Multiple models and materials are available to match specific plant capacities and working conditions.

Applications


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

    1. Animal By-Products – Low-fat meat and poultry waste, bone residues, and rendering by-products.
