Abstract
The deep-fat fryer has an upper basket (41), a heating source (8) below and a heat exchanger in between (13) for the exchange of heat between a gaseous heat exchange medium (57) and the frying oil (55). Thereby thermosiphonic oil circulation results. A blower (29, 31, 32, 33) is arranged, whereof a blower rotor (31) imparts a higher velocity of flow to the heat exchange medium (57) in the heat exchanger (13). The blower (29, 31 through 33) is arranged in the fresh air supply duct (56), in the gas vent (57) and in the cool air supply duct (58) for cooling the flue gases. The three blower wheels (31 through 33) are arranged on one and the same drive shaft (30). This deep-fat fryer takes significantly better advantage of the heat conducted to it. With large energy densities relative to the oil volume, it has minimal specific heating surface loadings and thereby affords optimal relationships.
