An indirect batch paddle dryer removes moisture by transferring heat through the walls of a jacketed drying vessel, while rotating paddles continuously mix the material.

Direct drying brings heated air or gas into contact with the material. Indirect drying transfers heat through a surface separating the heat source from the product.

Indirect paddle dryers can process wet powders, filter cakes, pastes, slurries, granules, crystals, sticky materials, and other products requiring controlled moisture removal.

Yes. Controlled indirect heating and optional vacuum operation make the dryer well suited to materials that require lower or carefully controlled drying temperatures.

A vacuum lowers the boiling point of moisture, allowing evaporation at lower temperatures. This can help shorten drying cycles and protect temperature-sensitive materials.

Yes. Optional high-speed choppers can break apart agglomerates during drying.

Yes. Scott Equipment offers testing to evaluate moisture targets, cycle times, energy consumption, and product integrity before selecting a production system.
