ABSTRACT:

Preservation of food and vegetables by removing moisture present in it is a old traditional technique. The heat present in the sun rays accomplishes this task very easily and economically. To expedite the drying process the solar dryers play vital role. In the study a forced convection system is used to make the drying process fast. Onion, potatoes, spinach and green chillies were dried with help designed solar drier and it is found that onion which is fully moisture vegetables dried up to 91% and potatoes dried up to 88% within 24hrs. While spinach and green chillies dried up to 73% and 67% within 8 hrs.
