Design of Air Preheater for Solar Dryer for Drying Cereals (140083)

DOI :

Abstract : This paper expla ins about various factors which are to be considering while designing solar dryer for agriculture products. It includes the major part s like air pre heater,air duct,and cabin for keeping agricultura l products. Out of these parts of air pre heater is important as solar energy is available in attuned form & we have to concentrate it with help of solar collectors. In c ollectors absorber plates are made up of good thermal conductor like copper,aluminium so the plate is get heated due to solar radiation & hence air is h eated by the convection process by forcing the air to flow over absorber plate & this heated air is directed towards the cabin through ducts . After that heated air is made to flow over agri cultural product s specially cereals lying in the cabin which is a closed space having number of trays placed in vertical shell with suitable distance & heated air takes away moisture present in it.
