ABSTRACT:
A jacketed kettle on a trunnion mount is tiltable for pouring a contained liquid. The inside of the kettle has a central substantially cylindrical portion that permits an agitator to be driven from the underside of the kettle while making a liquid seal above the contained liquid surface. The jacket may contain water which is heated by an immersed thermostatically controlled electric heater. A sight glass mounted into the outside of the kettle provides a visual indication of the water level in the jacket. Continuation of the outside of the kettle below the jacket provides a covered enclosure for a motor that drives the agitator by means of a gear drive unit, and for necessary electrical connectors. A symmetric agitator provides for wiping at or near the kettle inside surface and the surface of the central cylindrical portion of the kettle, and for mixing liquid within the kettle. The kettle is balanced for tipping by a lever and for return to the vertical position upon release of the lever. In an alternate embodiment, a symmetrical agitator provides scraping contact with the inside surface of the kettle.
