DEFINITION

Classification: 62/535

(under subclass 534) Processes wherein the liquid refrigerant which has vaporized in cooling the solution or mixture is brought into direct physical contact with solidified product or liquid product separated from the solution or mixture to melt the solid product or rewarm the liquid product.
