paddy husker is a by-product of rice and has a good value as a biomass fuel. This biomass amounts to 20% of total rough rice (paddy) produced. Rice husk is mainly used as fuel for parboiling and drying of paddy before milling.
In a study conducted in West Bengal, India, it was reported that 1,659 MJ of biomass energy was consumed for rice parboiling. In a study by the IDRC (International Development Research Center, Canada) it was reported that theoretically the net energy demand for hot soaking, steaming and drying were 360 MJ, 105.5 MJ and 574 MJ, respectively, to process one tonne of paddy. It was also mentioned that about 200 kg of rice husk (2,800 MJ) was needed to process one tonne of paddy if the efficiency of a husk fired boiler is 45%.
After the magnet is size paddy separator for removal of rubbles by coarse sieve and sand and dust by the fine sieve. Aspiration channel is used to remove light impurities and dust.
