REVIEW OF THE AERODYNAMICS AND PARTICLE DYNAMICS FOR COFFEE SEPARATION
The importance of agriculture in mitigating the effects of overdependence on crude oil export to boost Nigeria economy cannot be overemphasized. Coffee is an important foreign exchange earner and Nigeria has vast potential to resuscitate production, processing and export. An important first step to earn a premium on coffee is to ensure quality post-harvest practices which include cleaning sorting and classification which at present is either lacking or inadequate, given the poor price coffee of Nigeria origin currently attracts. This study reviewed a few notable research works on the aerodynamic of coffee and other notable works on its particle dynamics and related studies in agriculture. The subject of particle dynamics for coffee separation was lacking, hence the need to undertake detailed study on the subject the outcome of which would be to obtain particle trajectories of coffee beans and components as a basis to select the dimensions of a cross flow system to classify coffee beans which is a major requirement in coffee trade worldwide.
