Innovative Solution for Coffee Processing in Peru

In Peru, coffee cultivation is predominantly carried out by smallholder farmers who utilize the wet processing method to handle their coffee beans. This method involves extracting the pulp from the harvested coffee cherries and fermenting the beans in tanks to facilitate the removal of the sticky mucilage surrounding them. Subsequently, the beans are washed with water to eliminate any remaining mucilage. However, this final step not only requires significant labour but also consumes substantial amounts of water, which often leads to improper discharge and contamination of water bodies. To address these challenges, NRI researchers employed Simulation-driven Participatory Technology Development. This approach uses Multiphysics simulation and involves end-users and manufacturers throughout the design and development process. Through this collaborative effort, they have successfully developed a simple and cost-effective machine. This machine not only reduced the labour required for mucilage removal but also minimized water consumption.
