Project Name : Solar Heater with Storage Facility.
Theme Name : Agriculture and Food Security
Our project primarily focuses on two major issues, what India has and what India needs. According to us what India has is abundance of solar energy and what India needs is green agriculture and food security. We have used solar energy to dry agricultural products. The dryer consist of a metal box fitted with a glass top to allow light transmission. It also has a second compartment in which oiled gravel is spread at the bottom this second compartment is used for prolonged drying even if the amount of sunlight is limited.
Its advantages are:
Uniform drying of all products kept inside with minimum cost.
Colour and flavor is retained to a large extent.
Reduces the duration of drying compared to conventional methods.
No pollution.
More hygienic and no contamination of food items.
Food security is taken care of because we make use of „used cooking oil‟ to oil the gravel.
The neat stored in the gravel is used for prolonged drying even when the intensity of sunlight decreases.
