Drying is a most important method to reduce the moisture content from product to increase the self-life and quality of the product, which can be used for medicine purpose and non available purpose. During experiment different parameters for mint leaves was calculated under this study such as variation of temperature, collector efficiency, moisture content and solar intensity. In this study was used semi transparent polythene as a collector with size of 200 micron. During experiment with in six days air velocity was varies .51 to 1.21 m/s and average relative humidity was varies 41 to 57 % and exhaust fan speed was constant during this study that means it was 500 rpm. The average temperature inside solar tunnel dryer was varies 54 to 59 ˚c. Finally moisture content in mint leaves was 6.2 % and it’s observed that relative humidity decrease with increase temperature and moisture content also decrease. Collector efficiency was varied from 44% to 56%.

Key words: Mint Leaves, Solar dryer, tunnel dryer, tray dryer. Color value, dehydration, infrared.
