Paddle Dryer (Recuperative Type)

Paddle Dryer is a Conduction type Dryer. The Paddle Dryer is constructed by wedge-shaped paddles, two hollow shafts, and a jacket. Heat carrier can pass through the paddles, the shaft and the jacket. During drying, feed is supplied to one end of the dryer and is continuously transferred to the other end. Feed in the paddle dryer is continuously agitated by the rotating paddles, and is thermally dried by the heat from the heat carrier.
The jacketed half cylinder and agitator are designed to meet the operating pressures and material compatibility requirements for each individual application and are built to comply with ASME, PED Pressure Codes or other national design and construction codes.

Our Paddle dryers is recuperative type. All the heat generated during the drying operation is reused for further drying of incoming materials which makes it most cheap Drying cost Dryers.

Features of RAYGM Paddle Dryer

  • Carefully designed lifting louvers Ploughs, paddles to maximize contact between product and hot surfaces which results in high heat transfer and better efficiencies. Lowers the Drying Cost.
  • Material contact surfaces can be manufactured from wear-resistant materials or corrosion resistant lining, so Dryer will last a long time between servicing.
  • Designed to withstand both high temperatures and abrasive materials.
  • High specific loading as high as 60% volume of the Dryer.
  • Working at low Speed so less wear and tear, less breakdown, less maintenance.
  • Compact Design.
  • High Heat transfer co-efficient with proper design.
  • No fouling of surfaces over the time.
