Objective of the present study was to design, develop and to carry out detail experimentation and then analyze solar cabinet dryer. For these various types of solar dryer, their principles and design methods, modeling, drying temperature, efficiency, utilization of dryer and payback period were reviewed. In the present study, solar cabinet dryer is constructed at Mechanical Engineering Department, M.N.I.T, Jaipur, latitude (26.01° N). The measurement of solar intensity, temperatures, relative humidity and wind speed were taken for two spells (i.e first spell from 11May- 22 May2010, second spell from 18 Dec -22 Jan.2011). Seven different cases (for different glazing and insulation) were studied during experimentation. The maximum temperature of absorber plate and efficiency was seen with glass glazing.
