- Coffee, an agricultural commodity with such tremendous growth in supply and demand has a lot of elements which affects its final quality. These elements vary from the crop, variety, climate, cultivation, harvest and post-harvest operations. One of the major post-harvest operations which impact on the quality of the coffee is depulping. This work highlights the design, fabrication and working process of a coffee bean depulping machine, developed at the National Center for Agricultural Mechanization (NCAM) which was improved from an existing machine. The coffee depulping machine was operated by a prime mover running at 800 rpm after being soaked for two hours. Performance evaluation revealed that the machine had an average depulping efficiency of 96.6% with machine throughput of 4.67 kg/sec. More importantly is the fact that the depulped coffee beans was not crushed by the machine which was an improvement over the initial prototype developed.
