Determination of Head Load and Power Requirement for Development of BIN Type Paddy Dryer
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2018, Vol 8, Issue 2
Abstract
Harvested paddy grain with high moisture content must be dried to about 12 per cent (w. b) within 24 hours for safe storage and milling. The amount moisture evaporated from paddy was 86.64 kg. batch-1 of 500 kg paddy dried from moisture content of from 25 % (w. b) to 12 % (w. b). The bulk density of paddy was determined 609 kg. m-3 at 25.0 % (w. b) moisture content Heat transfer from the paddy was calculated 2.26 MJ kg –1 as bottom layer and top layer grain temperature 600C and 300C respectively. Total heat was calculated 250 MJ for a period of 8 hours paddy drying. Height of the air column was calculated 247.0 m for pressure drop of 63.17 cm of water. The pPower requirement for blower calculated as 3.0 Hhp for 500 kg paddy bin drying. Based on the design calculation 500 kg capacity paddy dryer was developed.
