Avaliação de modelos matemáticos na cinética de secagem de fatias de abacaxi pérola.

Abstract

In this work it was studied the kinetics of drying of pineapple variety Pearl, cut into slices, without stalk, with a thickness of 0.5 cm in the fixed bed dryer, at temperatures of 70, 60 and 50° C with drying air velocity of 1.4 m s-1. The mathematical models for Page, Henderson and Lewis & Pabis were adjusted to the experimental data. It was observed that the studied models fit well to the experimental data and can be applied in predicting the drying of slices of pineapple, and the best result was found for the mathematical model of Page.
