Hybrid Solar Box Type Dryer cum Cooker of Chilly Drying For Domestic Usage

The energy has become a basic need in todays life with drastic increase in power consumption, there is a need to search for an alternate energy source. Solar energy is one such established reliable source. Solar dryer and cooker are used to make use of solar heat energy for domestic use in rural areas but, it is working on ambient temperature and high initial cost is one of the major problems for poor rural people. The present research was conducted on design and development of a low cost hybrid solution for minimise the problems. The function is to developed hybrid dryer cum cooker was work on both electric and solar energy and those where enable to use it in early morning hours and on cloudy days, or when solar radiation decreases or disappears either as a dryer or as a cooker. A thermal performance test of developed solar cooker cum dryer was conducted for solar and for hybrid solutions. The data were evaluated by automatic sensor system for hourly period. The experimental results were thermal efficiency of solar dryer 23.42 %, hybrid dryer 38.56 % and solar cooker was 29.39 %.
