US 4,173,925 A · Variable tilt rotating pot cooker and mixer

Abstract

A heated, variable tilt, rotating container or pot for making possible automatic, continuous mixing or tumbling, with or without simultaneous heating, of a plurality of foods or substances. The device consists of an outer non-rotating shell pivoting on a fixed base. Inside the shell is a pot rotated by a motor attached to the bottom of the shell. A cover is secured over the pot to prevent the contents from spilling out. The shell and its pot are tiltable as a unit to any angular position from vertical to horizontal. Compartments, dividers, ridges, projections or other shapes are inside the rotating pot or on the pot wall and/or bottom, to separate, move, mix and tumble the contents when the tilt angle of the pot is other than at the vertical position. The shell contains a suitable heating system for raising the temperature of the pot. The device is provided with an automatic temperature control, motor speed control and automatic time cycle and function indicators.
