Abstract
A melting tank for melting a gelled substance charged therein. The walls of the tank are heating. A first agitating blade agitates the bulk of the gelled substance to promote heat exchange with the walls. A second agitating blade is located closely adjacent a screen separating the gelled substance from a port at the bottom of the tank that is left open during agitation. Thereby, the melt flows down the walls of the tank and flows through the screen to the port.
