Drying kinetics of quinoa-supplemented feed for laboratory rats during processing at 50, 60, 70, 80 and 90ºC was
studied and modeled in this work. Desorption isotherm was obtained at 60ºC giving a monolayer moisture content
of 0.04 g water/g d.m. The experimental drying curves showed that drying process took place only in the falling rate
period. Several thin-layer drying equations available in the literature were evaluated based on determination
coefficient (r2), sum squared errors (SSE) and Chi-square (c2) statisticals. In comparison to the experimental
moisture values, the values estimated with the Logarithmic model gave the best fit quality (r2 >0.994, SSE <
0.00015 and c2 < 0.00018), showing this equation could predict very accurately the drying time of rat feed under
the operative conditions applied.
