What is Rotary Vacuum Paddle Dryer(RVPD)
Rotary Vacuum Paddle Dryer (RVPD) is a cylindrical vessel with a large diameter hollow shaft and a jacket or limpet coil for heating.
The jacket/limpet coil and hollow shaft with paddles can be heated with hot water, steam, or thermal fluid, and cooled with water, brine, or refrigerant.
The hollow shaft has specially designed scraper blades to continuously move and rotate the material, preventing it from staying in contact with hot surface for too long. Heavy-duty trunnions and bearings support the hollow shaft and its drive through a motor, reduction gears, chain, and sprocket.
In some cases, a stationary scraper blade can be added for handling highly sticky materials. The dryer also has arrangements for nitrogen purging and bag cleaning with pulsation by nitrogen jet injector, and the shaft has hard-facing near gland packing areas of trunions.
