Development of an Advanced Gas-Fired Deep-Fat Fryer Based on the Heat TransferFluid Concept. Final Report, May 1994-May 1995

摘要

The objective of this project was to develop and commercialize and advanced, highefficiency deep-fat fryer for application in chain restaurants based on the Heat Transfer Fluid (HTF) concept. Deep-fat fryers represent a major use of energy in chain restaurants. The goals for this advanced fryer are to retain the high efficiency levels already achieved by gas while improving reliability and overall performance. In the HTF concept, hot oil (heat transfer fluid) is circulated in a closed loop through a heat exchanger located in the shortening (fry vat). The HTF fryer has a number of advantages including easy cleaning of the vat, improved oil life, reduce fire potential, and rapid response to load with minimum overshoot. After an extensive search, no pumps were found that could meet the performance requirements of the fryer at a cost consistent with the $490 cost premium. The project was terminated when it became apparent that the market objectives could not be met.
