Simultaneous heat and mass transfer during the cooling of a deep bed of biological products under varying inlet air conditions

Abstract

The cooling and dehydration of a deep bed of high moisture content cherry pits was investigated experimentally and the data were analysed by writing three heat and mass transfer balances. The inlet air conditions were changed continuously during the test period; the initial product temperature distribution within the bed was not uniform. The set of coupled equations resulting from the transfer balances were solved numerically with the aid of a digital computer. The empirical and theoretical heat and mass transfer agreed well.
