This is a dryer in which moisture removal takes place by means of forced draft action created by hot air. The set-up consists of an insulated double wall chamber. Inside the chamber a tray is attached directly to a electronic weighing balance, which is fitted on the bottom, outside the chamber. Material for drying is placed in the tray and regular loss of weight is monitored. Air from a blower passes through a heating chamber and is used as drying agent. Arrangement is done to vary the airflow rate.

• An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.
  
• The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Pain
  

Utilities Required:

• Electricity Supply: Single Phase, 220 V AC, 50 Hz, 5-15 Amp. Combined socket with earth connection. Earth voltage should be less than 5 volts.
  
• Wet Solid.
  
• Floor area required: 2.0m x 0.75m
  

Experimentation/Learning Objectives:

• To study the drying characteristics of a solid under forced draft condition and determine the critical moisture content.
  
• To correlate the constant drying rate with air mass velocity.
