가나 동부지역에서 곡물 건조를 위한 농업부산물 바이이오매스 활용방안 연구

Storage losses have been found to be the major contributing factor to postharvest losses crops in Ghana. This is mostly brought about by mould and insect infestation partly due to unsafe moisture levels of products for storage. Agricultural residues are generated in larger quantities in the eastern region of Ghana and mostly burnt to make way for subsequent farming seasons. This research studies the use of these residues (maize cobs, rice husks, groundnut kernels and cassava stems) as fuel for the drying of major commodities as maize, groundnut and cassava in the eastern region of Ghana and the resulting reduction in deforestation and carbon emissions. The energy consumption of some biomass-fed dryers was used to estimate the drying energy demand for these available commodities. The biomass-fed dryers considered included Dryer1 (Tran et al., 2015), Dryer2 (Dhasnushkodi et al., 2015), Dryer3 (Gunathilake, 2018) with consumption per ton of moisture removal as 5.8GJ, 14.3GJ and 19.86GJ respectively. The average energy demands per district for drying of the referred commodities were found to be 65087GJ, 143051GJ and 198886GJ for Dryer1, Dryer2 and Dryer3 respectively. The residues were estimated from the crops production figures and the residue to product ratio of 0.29, 0.26, 0.37 and 0.192 for maize cobs, rice husks, groundnut kernels and cassava stems respectively. The estimated average annual residues generated per district were 4240Mt, 324Mt, 156Mt and 40238Mt for maize cobs, rice husks, groundnut kernels and cassava stems respectively. 67977GJ, 3651GJ, 2161GJ and 127964GJ were estimated to be the energies to be realized annually in every district for the residues in respective order as stated previously. It was realized that for dryer 1, energies from only maize cobs, rice husks and groundnut kernels will be enough to dry commodities unlike dryers 2 and 3. A storage system and optimization strategy for full utilization of those residues will be proposed. An assessment of the reduction of carbon emissions as a result of the use of available residues rather than fossil fuels will be done. The reduction is expected to be significant to impact positively on the environment.
