Provided is a system for automatically coating an inner surface of a kitchen receptacle by using an air condenser, thereby reducing energy by quenching the heated receptacle through a cooling unit in an efficient cooling system. A coating system has a first cooling unit(300), an air condenser(320) supplying cooled air, a cooling tube(310) equipped with plural spraying holes for spraying the cooled air of the air condenser, and a return tube(330) for returning the cooled air which is sprayed through the spraying holes of the cooling tube to the air condenser. The system includes a primer coating unit, a primer layer drying unit, a mid-layer and top layer coating unit, a mid-layer and top layer drying unit, a second cooling unit, a marble layer coating unit, and controller.
