A numerical study of the bulk hydraircooling of spherical food products is performed using the technique of spraying chilled water to form a thin film over the food products while blowing cold unsaturated air in the countercurrent or cocurrent direction. This precooling process is found to combine the advantages of hydro-and air cooling.Governing equations describing the simultaneous heat and mass transfer occurring in the hydraircooling process for both counterflow and parallel-flow arrangements are solved using finite-difference numerical methods. A parametric study is performed to determine the effect of important processing parameters on the process time. It is generally observed that higher quantities of spray water, air-mass flow rate and product thermal conductivity, as well as lower values of water temperature will result in faster rates of cooling. For the same operating conditions, parallel-flow arrangement leads to higher plant capacities.
