Dispenser which incrementally heats fluids with substantial non-volatile constituent parts
The present invention discloses a method and apparatus for quickly heating a predetermined volume of viscous fluid and dispensing it efficiently at one or more selected temperatures. The viscous fluid includes substantial non-volatile constituent parts. In one embodiment, the predetermined volume of viscous fluid is partially housed in a predelivery chamber separate from the main fluid reservoir. A heater assembly heats the viscous fluid in the predelivery chamber in a short time period and in small volumes to prevent overheating and adversely effecting the composition of the viscous fluid. To avoid continually heating the viscous liquid, a timer circuit is used in one embodiment.
