Abstract
A cooling system for post-mix beverage dispenser includes an ice bath tank for holding a liquid, a refrigeration circuit for cooling the liquid in the ice bath tank, a concentrate storage area, and a cooling circuit coupled to the ice bath tank, for cooling the concentrate storage area. A pump in the cooling circuit transfers the liquid from the ice bath tank to a coil in the concentrate storage container. The circuit returns the liquid to the ice bath tank and creates the turbulence necessary for the liquid to freeze evenly in the tank. Thus, an agitator assembly is not necessary. A fan in the concentrate storage area circulates air over the coil. The pump can be selectively coupled to drain the tank.
