Abstract:

This research work presents the development of a vertical centrifugal filter for the separation of mucilage and water in the coffee demucilagination process in the province of Chanchamayo. The coffee demucilagination process is a crucial stage in the production of high-quality coffee, as it removes the mucilage, a sticky substance that surrounds the coffee beans. Traditionally, this process consumes large amounts of water and generates wastewater containing high levels of organic matter and sugars, contributing to the contamination of local water bodies. In the province of Chanchamayo, one of Peru's main coffeegrowing regions, this issue has gained relevance due to the increasing demand for sustainable agricultural practices and the scarcity of water resources. In response to these challenges, the design of a vertical centrifugal filter is proposed, an innovative device aimed at reusing water in the demucilagination process. It features a frequency inverter to regulate the necessary RPM of the 1 HP electric motor, which spins the fine mesh centrifugal filter (0.5 mm), effectively separating the mucilage from the water for reuse. This technology aims not only to reduce water consumption but also to minimize water pollution, contributing to environmental sustainability and improving process efficiency.
