Abstract
A refrigerated agitator assembly is provided including a rotatable agitator shaft, first and second split hub assemblies, and a plurality of agitator tubes. The rotatable agitator shaft defines a fluid supply passage, a fluid supply port, and a fluid return port. The first split hub assembly is secured proximate a first end of the agitator shaft so as to be rotatable with the agitator shaft. The first split hub assembly defines a supply hub duct coupled to the fluid supply port and a return hub duct coupled to the fluid return port. The second split hub assembly is secured proximate a second end of the agitator shaft so as to be rotatable with the agitator shaft and defines a transfer hub duct. A first agitator tube is secured to the first and second split hub assemblies and extends from the supply hub duct of the first split hub assembly to the transfer hub duct of the second split hub assembly. A second agitator tube is secured to the first and second split hub assemblies and extends from the transfer hub duct of the second split hub assembly to the return hub duct of the first split hub assembly.
