ABSTRACT:
A fountain for heating and distributing fluidic material is manufactured using various processes and materials so that the fountain is more easily cleaned and sanitized, has improved performance, and is easier to assemble. In one embodiment, the chocolate fountain includes a heating element encased in an aluminum enclosure. A basin containing chocolate is heated by contact with the aluminum enclosure. Because the aluminum enclosure has a relatively high thermal conductivity, the basin is heating substantially uniformly, thus reducing the occurrence of hot spots. Additionally, a plastic auger having a spiral flight rotates and lifts the melted chocolate upward to a top end of cylinder that houses the auger. The use of a plastic auger advantageously eliminates welding artifacts on the auger, such as burrs and pits, on which melted chocolate may accumulate. Accordingly, the plastic auger is easy to clean. A smaller chocolate fountain that may advantageously be more suitable for home use is also described herein.
