Kinetic modelling of drying of three varieties of yucca industrial

Abstract

Drying of three varieties of cassava, was conducted in a tunnel type dryer; the effect of temperature, variety and velocity of drying air on the drying time, using a completely randomized design in factorial arrangement with three factors: temperature (45, 55 and 70°C), speed drying air (1, 3 and 4 m/s) and range (Corpoica Tai, Gines and Veronica), performing three replicates per treatment, resulting in a decrease in drying time to the temperature of 70 ° C for the three varieties. The results obtained were built drying curves, in which it was found that this process took place in the period decreasing. Drying curves were fitted to mathematical models, determining by the R2 and the sum of squared errors (SSE), that page is the model that best describes the drying process.
