SECAFÉ Parte I: modelamiento y simulación matemática en el secado mecánico de café pergamino

Abstract: RESUMENSe implementó en lenguaje de programación Microsoft Visual Basic 6.0, dos programas de simulación matemática para el secado de café pergamino, tomando como base los modelos de Thompson y de la Universidad del Estado de Michigan (MSU), para lo cual se utilizaron los parámetros determinados en Cenicafé para la simulación matemática del secado de café pergamino. Los programas estiman el funcionamiento de cada uno de los secadores mecánicos de café existentes en Colombia. Se compararon los resultados obteni… Show more

“…Figure 2 shows mean drying speed obtained during functionality tests of the prototype for the three different air speeds. A reduction in speed occurred during the decreasing phase which coincided with typical performance for agricultural products during drying (Parra-Coronado et al, 2008). The final product was obtained with 0.11 mean CHdb.…”

“…En la figura 2 se registra la velocidad media de secado obtenidadurante las pruebas de funcionalidad del prototipo para las tres diferentes velocidades del flujo de aire. En la fase decreciente se presenta una disminución de la velocidad de secado, lo cual concuerda con el comportamiento típico de productos agrícolas durante el secado (Parra-Coronado et al, 2008). La humedad final en base seca (Chbs) del producto fue 0,11.…”

“…Parra‐Coronado et al (2008) established the thin layer drying equation Equation (11), and its parameters m = 0.0143, n = 0.87898, and q = 1.06439. Valid for moisture content and temperature between 5–55% (d.b) and 10–70°C.…”

“…The solar drying requires direct sun exposure in handcrafted drying structures known as marquesina . For the mechanical drying a three‐mesh trays static dryer is frequently used in a forced hot air convection, it uses fuels such as; coal, wood, coffee chaff, propane gas (Deeto et al, 2018; Duque‐Dussán & Banout, 2022; Parra‐Coronado et al, 2008a, 2008b).…”
