Scope of Studies:  
•    To study the effect of air flow rate on the rate of drying. Also draw a graph between
o    Air flow rate and rate of drying.
o    Moisture content and drying rate
•    To study the effect of air temperature on the rate of drying. Draw a graph between moisture content and drawing rate.
•    To study the effect of material of the drying time. Also draw a graph between time of drying and material used.
•    Material and Engineering balance on tray dryer.
