A recirculating-type deep fat fryer has a generally rectangular tank, a heat exchanger externally of the tank and a pump and tubing for recirculating fat from an inlet at the tank bottom, through the heat exchanger and to an outlet which is just below the upper level of fat and essentially midway between the sides of the tank. A deflector is provided adjacent the outlet to divert fat returning through the outlet along the side walls and throughout the tank to provide a “forced”horizontal convection. A pair of food-containing baskets are immersed in the fat with space between the baskets and between the outer sides of the baskets and adjacent walls of the tank. Convection results in heated fat being essentially uniformly distributed around the sides of both baskets and through the food, resulting in more uniform, even frying.

The method of deep fat frying of food in a substantially rectangular tank provided with an external heat exchanger and a recirculating system having a pump and tubing for receiving fat from the bottom of the tank, passing it through the heat exchanger where it is reheated, and returning the reheated fat through an outlet at a level just below the upper surface of the fat and essentially midway between adjacent side walls of the tank, comprising the steps of: pumping the fat at a flow rate sufficient to cause fat, if it were unobstructed as it exits from the outlet, to readily cross said tank and contact the tank side wall opposite the outlet, deflecting fat exiting from said outlet in opposite horizontal directions toward said adjacent side wall, thereby providing horizontal convection currents around the sides of said tank for merging at the wall opposite said outlet and returning back toward said outlet, essentially centrally of said tank.
