Convection and radiation sludge drying pilot.
The heating is done by two devices:
By radiation: by two lamps simulating the sun.
By convection: a fan and an electric air heater. Both adjustable

Educational Objectives :
  • Comparison of the drying efficiency of a radiant or convection heater or a combined system.
  • Study of the efficiency of the mixing of the material on the drying time  
  • Make the energy balance / quantity of evaporated water.  
  • Study of the influence of heating parameters on the drying speed.
  • Take a water balance
  • The measurements relate to: the weight of the material, the humidity of the air, the air temperature, the energy consumed and the air flow
Technical specifications :

The material to be dried is placed in a circular stainless steel tray, whose   base is porous to promote ventilation. The tray is located in a closed box-shaped enclosure with a transparent door. During drying, the material is stirred continuously to promote ventilation.
