초록 ▼

Disclosed is a high efficiency deep fat fryer from whose fry tank fat is continuously withdrawn for heating and filtration. A pump circulates part of this fat through a helical- or serpentine-shaped finned-tube heat exchanger positioned between a gas-fired burner and the bottom of the fry tank. The remaining portion of fat is directed through a filter located in the bottom zone of the fry tank. The fryer includes a control system with sensors such as pressure switches for preventing damage to the fat at low flow rates and devices for expelling moisture trapped in the pump. The filter has an element of material such as carbon-impregnated cloth which may be quickly replaced without draining fat from the tank.
