A cooling tunnel having an L-shaped cross-section defining a horizontal leg and a vertical leg. The material-receiving run of a continuous conveyor passes through the horizontal leg, and the reverse conveyor run is located outside the tunnel. An evaporator is arranged within the vertical leg, and a guide sheet extends from the evaporator into the horizontal leg dividing the latter into upper and lower cooling zones. A ventilator directs air downwardly through the evaporator and through the cooling zones in directions perpendicular to the direction of movement of the conveyor. The lower end of the vertical leg is formed to collect condensation and is provided with an outlet for removing condensed water.
