Simulated inactivation model for coffee peel disinfection in a germicidal chamber with ultraviolet radiation using Monte Carlo simulation and image analysis

Abstract

El café colombiano es reconocido mundialmente por su calidad y su papel en el comercio internacional. Sin embargo, la producción de más de 700,000 toneladas de residuos anuales, principalmente cáscaras de café, plantea desafíos ambientales y sanitarios. La investigación se centra en estudiar el efecto de la irradiación ultravioleta (UV) en estas cáscaras, para mitigar su alta carga microbiana Mediante la variación de la distancia y tiempo de exposición del UV, se determinó la dosis requerida para la descontaminación. The Colombian coffee sector is internationally renowned for its quality and role in global trade. However, the production of over 700,000 tons of waste annually, primarily coffee husks, poses environmental and sanitary challenges. This research focuses on studying the effect of ultraviolet (UV) irradiation on these husks to mitigate their high microbial load. By varying the distance and exposure time of UV, the required dose for decontamination was determined. Additionally, morphological parameters were analyzed, and electromagnetic radiation dynamics equations were employed in an industrial germicidal chamber.
