Paddle Dryers

Paddle Dryers

A paddle dryer is a type of indirect dryer using rotating paddles to agitate and move the material being dried. Unlike direct dryers that rely on direct contact with hot air or gas, paddle dryers use indirect heat transfer. This makes them suitable for sensitive materials that cannot withstand high temperatures. The heat transfers through the paddles and the walls of the dryer, ensuring uniform drying without overheating or damaging the product.

The working principle of a paddle dryer is straightforward. The material to be dried enters the dryer, where heated paddles and dryer walls come into contact with it. These paddles are mounted on a rotating shaft, ensuring continuous movement and agitation of the material. The heat transfers indirectly from the paddles and the walls, evaporating the moisture from the material. The exhaust system then removes the evaporated moisture, ensuring a dry and processed final product. Several key features make paddle dryers highly efficient and suitable for various applications:

Key Features of Paddle Dryers

• Indirect Heating: Prevents direct contact between the material and the heating source, ensuring that sensitive materials are dried without degradation.
• Uniform Drying: Continuous movement and agitation of the material by the paddles ensure uniform drying, preventing hot spots and ensuring consistent product quality.
• Energy Efficiency: Designed to maximize energy efficiency by utilizing the heat effectively and minimizing heat loss.
• Versatility: Can handle a wide range of materials, including powders, granules, pastes, and slurries, making them suitable for various industries.
• Compact Design: The compact design makes them suitable for installations where space is limited.
