Abstract: The application of techniques of simulation of cooling processes may become an important and practical tool as it allows predicting with great approximation the response of the horticultural crops to the cooling process. This work presents a mathematical model and numeric simulation to describe the cooling process of a solid particles bed of different geometry, considering the dimensions of commercial packages. The equations that describe the balance of mass and energy for the product and for the cooling mean are resolved applying the Finite Volume Method. The numeric results are compared to experimental data obtained during the cooling process of orange (Citrus sinensis Osbeck L. 'Valencia') and banana (Musa cavendishi 'Prata') which were cooled in a forced-air tunnel at temperatures 1°C and 7°C, respectively (air velocity = 1 m/s; Q = 0.54 m3/s). The result of the distributions of air temperature and of the product temperature along the bed of fruits is presented and discussed in this work.
