Rice Quality Evaluation of a Medium Scale Paddy Parboiling Vessel

Abstract

This study evaluated an efficient parboiling vessel developed by IPHT for enhancing production capacity of rural level rice Processors to increase their income while create self-employment among the rural farming sector. This medium scale vessel was modified with blower driven husk fired furnace. This vessel consists of two shapes of component; 1f upper component is 675 mm x 900 mmx 1200 mm cubical shape and bottom component is 250 mm height, inverted pyramid shape attached to the upper component. The capacity of vessel is 200 kg per batch and time consuming for complete parboiling was 21 minutes. The parboiling quality was measured according to the milling qualities of dried paddy. The total milling yield, broken percentage, discolored grain percentage and moisture content of paddy sample were 73.1%, 8.2% 2.6% and 12.7% respectively. This result proves that the performance is at acceptable level for implementing this vessel in field level.
