The electric heating body has an envelope (20, 21) made of a heat conductor material and an interchangeable electric heating element (25) plugged into the envelope (20, 21) which comprises a reception space. The envelope (20, 21) presents a channel (28) open at both ends to receive the heating element (25). The frier is provided with a tub (32) for the oil or the grease, which tub is prolonged by oblique walls (39) as a trough (33) and terminates into a sump (34). The temperature of the lower portion of the frier is here maintained by a gas heating (36) whereas in the upper part electric heating elements are provided. Due to the inclination of the tub walls and to the presence of heating elements (37) the melted grease flows into the trough (39) whereas the grease block (42) bears against the electrically heated trough walls (40) and is also melted. The heating elements are interchangeably mounted in the heating bodies. Thereby, when damaged, it is not necessary to replace the oil bowl but only the damaged elements (25, 27). |
