<p>Water from a water tank is sprayed through spraying openings against a plate and ends, projecting underneath the plate, of metal rods. These rods are clamped between line portions through which cooling liquid flows in opposite directions. The excess water returns to water tank over a collecting tray provided with an outlet. A movable water-guiding member is mounted underneath this outlet and is connected to a float in the water tank. When nearly enough ice has been formed, the water level in the tank has so fallen that the float brings the movable member in a position whereby it diverts water to a discharge pipe. The minimum level in tank, with which the cooling cycle is stopped and fresh water is supplied to tank over the first mentioned plate, is then quickly reached.</p> |
