High temperature vacuum steam distillation process to purify and increase the frylife of edible oils

Abstract From the Canadian patent

Abstract of the Disclosure Deaerated oil having a level of less than about 0.10% by volume of dissolved oxygen is heated at a temperature between about 530°F (277°C) and about 650°F (343°C) and stripped with a stripping medium with a molar ratio of stripping medium to oil of between about 0.05 and about 9.7 at an absolute pressure of between about 0.5 mm Hg and about 50 mm Hg. for a time of between about 5 seconds and about 15 minutes. The combination of stripping parameters is selected so that the stripping factor "f" is greater than about 0.6, where f = KPvS/PO, where K is between about 1 and about 200, and where Pv (the vapor pressure of the component to be stripped) is not more than …
