SOLAR PADDY DRYER WITH SOLAR PADDY COOKING SYSTEM

Paddy is a mandatory food crop in South India. Most of the Paddy farming is in rural areas. After harvesting, the paddy has to move through different stages. One of the important processes of paddy processing is paddy drying. In most of the rural farmers are using open space paddy drying method. It is not an efficient method, where space for open drying is decreasing, and this process is not hygienic one. Insects and dust particles may mix with paddy. Or otherwise, large machinery is using for paddy drying. It may not accessible for rural or small-scale farmers. Then solar paddy dryer is an alternative method that is useful for rural and small-scale farmers. Solar is renewable energy so; it is safe to process. Free of energy cost. The system is a hybrid one having a paddy dryer with a paddy cooking system. The harvested paddy has a two-stage process before milling for extracting rice, which is cooking partially first and drying. These two processes are satisfied with the system. The system has two chambers, one for cooking the paddy it is by the principle of solar cooker. Solar pressurized cooking is adapting for doing the cooking of paddy. And the suitable solar dryer is selected by software analysis. CFD analysis of solar indirect and mixed dryers is simulating in ANSYS software. Development of the product and testing of the system for the results.
