Abstract
The invention relates to a process for recovering heat from deodorized edible oils and stabilizing the same comprising: introducing or injecting non-condensible inert gas into hot deodorized edible oil as the hot deodorized edible oil is cooled by indirectly heat exchanging with crude oil to be deodorized.
Claims9
A process for cooling and stabilizing deodorized edible oils, which comprises sparging and dissolving non-condensible inert gas into hot deodorized edible oil as said hot deodorized edible oil is cooled to less than about 100.degree. C., wherein the amount of said non-condensible inert gas sparged is sufficient to promote uniform cooling and stability of the resulting, cooled deodorized edible oil.
