The deodorizing apparatus is used to treat organic liquids, such as edible oils or edible fats, in that they are stripped with water vapor under subatmospheric pressure and at temperature from about 130 DEG to 260 DEG C. The liquid to be treated is passed through one or more treating levels and is agitated therein by rising water vapor. At least one of the treating levels contains numerous conical circulating ducts, which can be flown through in an upward direction and are provided with a water vapor inlet in their lower portion, which is narrower in cross-section. The cone angle of the circulating duct measured against the vertical may vary from 5 DEG to 20 DEG C.
