Abstract
A fat recirculating system with an external, gas-heated heat exchanger for a deep fat fryer is disclosed. The use of such a system necessitates recirculation also of cleaning solution and rinse water through inaccessible plumbing of the recirculation system whenever fat is to be replaced. To remove residual water droplets from the plumbing after rinsing, a 'dry cycle' is utilized. The dry cycle includes intermittent application of heating and cooling of the empty heat exchanger, resulting in a substantial reduction in start-up time when the fryer is refilled and operation again commenced.
