Sludge drying pilot

• 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

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.

• Bench mounted on a frame made of stainless steel tubes and fitted with castors
