Acontinuous flow liquid-ice system was designed and tested for broccoli precooling. Ice particles were injected into a water stream, then the mixture was pumped into the box of produce. A granulometric method was adapted to measure ice particles. The effects of different ice particle sizes and ice-water ratios on the surface temperature of broccoli, the mass of ice remaining in the boxes of broccoli, and the icing efficiencies were analyzed. The results led to the establishment of recommended conditions for the operating parameters of the proposed system.
