Abstract: Frying device (1), comprising a frying tank (2) which can be filled with a frying medium. The frying tank consists of an upper part (18) and a shaft (20) which extends downwards and is open at the top. The bottom (19) of the upper part is connected by a number of pipes (26) to the side wall of the shaft so that the frying medium in the shaft is in open communication to the frying medium in the upper part. The pipes are enclosed by a tint heating chamber (27) with an inlet and an outlet (33) for heating gases. The first heating chamber is bounded by the bottom of the upper part and by the front wall of the shaft. The outlet (33) of the first heating chamber runs through the shaft to a second heating chamber (34), one of the walls of the second heating chamber being the rear wall (22) of the shaft.
