Resumo: | Drying is a process widely applied industrially, especially in food technology. It usually consists of a dehydration operation, removing enough water to halt microbial development. This allows an increased shelf life and a broader range of products available to the consumer, also reducing packaging, storage and transportation costs. This work presents a simple apple dehydration experiment, suited for the teaching of simultaneous mass and heat transfer in engineering classes. The procedure for drying sliced apples in a forced air oven is presented. Data collected was analyzed using the theoretical model proposed by Crank (Crank, 1975), so that it was possible to evaluate the effective diffusion coefficient of moisture. The empiric model proposed by Page (Page, 1949) was also tested to fit data. |

Normalmente consiste em uma operação de desidratação, removendo água suficiente para impedir o desenvolvimento microbiano. Isto permite o aumento da vida de prateleira dos produtos, e também uma maior gama de derivados disponíveis para o consumidor, reduzindo também custos de transporte, armazenamento e embalagem. Este trabalho apresenta um experimento simples de secagem de maçãs, adequado para o ensino de transferências de massa e calor simultâneas em aulas de engenharia. Foi apresentado o processo de secagem de maçãs finamente fatiadas em uma estufa de convecção forçada. Os dados coletados foram analisados utilizando-se o modelo teórico proposto por Crank (Crank, 1975), através do qual foi possível calcular o coeficiente de difusão efetivo da água. O modelo empírico de Page (Page, 1949) também foi testado para descrever a curva de secagem.
