A Study the Solar Energy Powered by Solar Dryers and its Mechanism

Enhancing Agricultural Product Preservation Using Solar Energy and Thermal Storage

Abstract

Sun drying is the most popular technique utilised to preserve agricultural products in India.The rate of drying is affected by a number of factors, including but not limited to: the amount of availablesolar radiation, the temperature & wind speed of the surrounding area, the initial moisture content of thecrop, the crop's absorptive surface area, and the product's mass per unit of exposed area. The dryingprocess is slowed by the sun's sporadic appearance, cloud cover, and rain. Due to the limited availabilityof solar power throughout the night, it is necessary to employ effective thermal energy storage in orderto utilise the daytime heat surplus. Continuous drying is often favoured over intermittent drying. Thepurpose of solar drying is to subject the product to higher temperatures than would normally beavailable in the surrounding environment.
