Carousel Dryer

Go Round for Gentle and Uniform drying
Each feed pellet is carefully treated.

THE PROCESS
  1. Round-shaped carousel dryer consists of a number of slowly rotating circular decks. Product to be dried is fed from the top tray.
  2. After nearly one revolution, product is discharged onto the next subjacent deck. During discharge process product is mixed, leveled again.
  3. This process is repeated until the product is discharged from the last tray into the outlet.
  4. Change of product without downtime, just allow one deck to be fully emptied.
  5. The airflow is vertical and going through the perforated circular trays.
  6. Product is moving in circles in a fixed counter-flow air flow.
  7. The product flow is first-in, first-out(FIFO). Every pellet is getting the same treatment by passing different air volumes and temperatures.
  8. Result is optimum drying uniformity.

 









Detail Design of Carousel Dryer

Designed for production of high-quality feed

         A. Adjustable retention time/
             Control of product layers

             Mix product with multiple tumbling

               


Increase Profit with a Carousel Dryer, It’s All About Water.
+/- 0.5% Moisture tolerance results in higher profit     

Moisture is controlled by the energy transfer into the dryer. Automatic air temperature and drying air volume control is the base to control the water evaporation capacity. Therefore, the target moisture is easy to accomplish by adjusting the inlet temperature and / or volume of process air.

MOISTURE CONTROL IN PRODUCT

With carousel dryer, the product is handled with more stable moisture control in-time, less over-drying (avoid product loss) and with higher average moisture content.





INCREASE MOISTURE TARGET WITH +/-0.5%

For those products sold by weight, a reduction in moisture tolerance allows the moisture set point to be higher, in result of more water sold with the product without exceeding the maximum moisture limit.

    Feed Keeps Running, Profit Keeps Rising

















Saving with a Carousel Dryer, Let’s Go Round
Energy saving and less need of odour treatment

ENERGY CONSUMPTION COMPARISON




  The IDAH advanced air system significantly reduce the energy consumption
             
 
OPTIMUM HEAT TRANSFER

  • A round-shaped carousel dryer generates a homogeneous air flow
  • Every drying zone has an independent automatic controlled air volume and temperature setting
  • Optimum heat transfer results in low exhaust air temperature and the option for re-circulation. Use of exhaust air from the cooler will increase drying efficiency.
