ABSTRACT:
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 temperatures from about 130.degree. to 260.degree. C. Free fatty acids and disturbing taste- and odor-imparting substances are thus removed. The liquid to be treated is passed through one or more treating stories and is agitated therein by rising water vapor. At least one of the treating stories comprises at least two concentric, open-topped annular passages having a common cylindrical wall, a vertical partition extending across the wall and an aperature in the wall adjacent the partition for allowing liquid flow between the passages. A plurality of circulating cylinders, which are adapted to be flown through in an upward direction, are arranged in each annular passage. Water vapor in the form of fine bubbles is passed through the circulating cylinders.
