Abstract

The invention relates to a thermal fluid fryer which essentially contains an oil-filled cooking channel disposed within a fryer tank support frame, in which the product to be fried is conveyed through the channel on a continuous food conveyor belt. The oil is heated indirectly by at least one heat-exchanger unit disposed substantially vertically in the channel. The heat-exchanger unit has an inlet manifold and an exit manifold, wherein a thermal fluid enters the heat-exchanger unit at the inlet manifold and exits through the exit manifold. The thermal fluid is heated to a higher temperature than the surrounding oil, and imparts its thermal energy to it efficiently by means of the heat exchanger unit. In this configuration, the temperature range distribution of the fryer oil inside the fryer vat is minimized from side to side and along the length thereof.
