Rotary Dryer

Peeler & Polisher In One Machine


What is it ?

Spectrum Industries introduces the Rotary Dryer to meet all the requirements of growers of agricultural produce. The Dryer can be used for drying products such as Pepper, Maize, Paddy, Pulses, Peanuts and other agricultural produce. It consists of a Rotating Drum which is mounted on two rigid stands. This also houses a suitable drive arrangement.

How it works ?

The Hot air is generated by means of an indirect Heat Exchanger which ensures that flue gases from the furnace are not mixed with the air used for drying the product. The Heat Exchanger is wood fired or optionally provided with a diesel Burner, with an automatic temperature controller, in order to allow for unattended and trouble-free operation of the machine.


  • Optional Wood and Diesel fired burners with automatic temperature controller.
  • Available in capacity ranges of 2,500 to 15,000 ltr. capacities based on requirement.
  • Highly efficient Radial turbines are used for silent operations with low power consumption.
  • Superior Heat Exchanger with higher efficiency for lowest consumption of fuel such as wood or Diesel.
