  • Patent number: 5234131
    Abstract: The present invention is a drink dispenser of the evaporator coil electric refrigeration system type which provides for an increased drink dispensing capacity. The present invention is provided with insulator pads affixed to the evaporator coils to prevent the ice bank from forming against a portion of the tank walls, and to provide a channel between the lower and upper portions of the tank to create an increased circulation of cooling liquid about the ice bank. That increased circulation increases the amount of heat that can be exchanged between the product lines and the cooling liquid, thereby increasing the amount of drinks that may be dispensed below a temperature of 40.degree. F.
