Performance Improvement Test on Natural Convection Solar Dryer System Using Mild Steel Chip

In today's world, as the demand for vegetables grows, so does the supply, and excess goods are thrown away. To avoid this, dryers are being used, and solar dryers are being used to reduce the moisture content. It is done organically without the need for added forces since the main power source is the sun, which is free. We use a direct solar dryer, which is exposed like an open sun dryer and functions somewhat like an indirect solar dryer. This is made of stainless steel and is made using sheet metal forming (SMF) and spot welding with toughened glass to allow solar energy to enter into the dryer and reach the specimen. The thermal conductivity values of the materials are examined and selected accordingly. The heat is contained inside the dryer cabinet to boost the moisture removal rate by raising the temperature, which is measured and recorded by a temperature sensor installed inside the cabinet. To improve this, we employ mild steel chip packing and cushions for insulation. The quantity of moisture content is recorded on a regular basis, together with the drying time and the beginning and final mass (or weight) of the item. It is then assessed and tabulated with efficiency. This helps to improve the export of dry food goods while keeping people out of poverty.
