Abstract

A fryer includes a frying tank adapted to contain a cooking liquid; a pump adapted to suck from the frying tank, by suction duct, a portion of the cooking liquid and adapted to discharge into the frying tank, by a discharge duct, the portion of the cooking liquid. The fryer also includes a heater associated with the suction duct and/or the discharge duct and adapted to heat the cooking liquid flowing through the suction duct and/or through the discharge duct, the cooking liquid being heated only by the heater; and at least one mixer associated with the suction duct and/or discharge duct and adapted to mix cooking liquid flowing through the suction duct and/or discharge duct. The mixer is placed immediately upstream or downstream, or in correspondence with the heater to improve the heat exchange of the cooking liquid with the heater.
