Ice making and unfreezing control device for an ice-making machine

Abstract: An ice making and unfreezing control device for an ice-making machine includes a compressor, a condenser, an electric magnetic valve, a dryer, a vaporizer, a liquid reservoir and a temperature sensor. The vaporizer has its underside provided with plural ice-making rods. The temperature inductor is positioned on the exit pipe of the vaporizer. By so designing, ice blocks can be made quickly, and when the temperature of the exit pipe of the vaporizer, detected by the temperature sensor, reaches the set value of unfreezing temperature, all the ice blocks will be separated from the ice-making rods, and the unfreezing work will be stopped and the electric magnetic valve will be turned off. Then, shoveling of the ice blocks begins and next cyclic ice-making work proceeds, able to quickly make ice blocks with a same size and shape and convenient to carry out unfreezing.
