In the present study, a flat plate film evaporator was evaluated at a pilot scale. The temperature of the juice and the plate was measured with thermocouples, and the concentration of the soluble solids of the juice was measured with a refractometer. Evaporator performance was determined through the heat transfer coefficient on the side of liquid ( h ), which was related to the following operating parameters: mass flow, surface temperature, and the temperature and concentration of the fed liquid. The coefficient h profited by increasing : surface temperature (from 140.8 to 181.2 °C), feed concentration (from 18 to 30 °Brix), and juice feed flow (from 5.7 to 38.4 kg/h), and by decreasing feed temperature (from 90 to 60 °C). In the evaporation of sugarcane juice in a flat plate evaporator, h values between 140 and 380 W/m 2 K were found, which show a marked improvement for evaporation process of sugarcane juice. 2013 artículo científico 0122-8706 https://www.redalyc.org/articulo.oa?id=449944862001 es http://www.redalyc.org/revista.oa?id=4499 Ciencia y Tecnología Agropecuaria application/pdf Corporación Colombiana de Investigación Agropecuaria Ciencia y Tecnología Agropecuaria (Colombia) Num.2 Vol.14 |
