ABSTRACT:
The waste water from an ice cube making machine, both from the cube unit itself and from the bin where the ice cubes are stored is supplied to an insulated heat exchanger. The heat exchanger is divided into two sections with a first cold input section being separated from the remaining portion of the unit by a baffle to avoid undue mixing of the water, and to maintain the water at the input section at a low temperature, near freezing. A heat exchange coil is located in the first section of the heat exchanger and water to be formed into ice is precooled by circulation through this coil. Additional coils are located in the remaining portion of the heat exchanger to further cool refrigerant liquid which has been condensed and is under pressure ready for return to the ice-making units. The temperature in the input section of the heat exchanger is in the order of 34 degrees F., and the temperature in the second section of the heat exchanger may range from about 38 degrees just beyond the baffle which separates the two sections up to about 98 or 100 degrees F. close to the output from this second section of the heat exchanger.
