The present study aimed to determine the volumetric shrinkage rate of bean
(Phaseolus vulgaris L.) seeds during air-drying under different conditions of air, temperature and
relative humidity, and to adjust several mathematical models to the empiric values observed, and
select the one that best represents the phenomenon. Six mathematical models were adjusted to the
experimental values to represent the phenomenon. It was determined the degree of adjustment of
each model from the value of the coefficient of determination, the behavior of the distribution of the
residuals, and the magnitude of the average relative and estimated errors. The rate of volumetric
shrinkage that occurred in bean seeds during drying is between 25 and 37%. It basically depends on
the final moisture content, regardless of the air conditions during drying. The Modified Bala &
Woods’ model best represented the process. [--]
