Here we have considered the problem of determination of temperature distribution and heat transfer rate during hydro cooling, a precooling method, of tomatoes as spherical products. Temperature values measured at the center and mass-average of the products were converted to the dimensionless form to obtain the dimensionless temperature distributions and variations of heat transfer rate. We have computed the dimensionless temperature values and heat transfer rates using appropriate boundary and initial conditions
