Zusammenfassung:	A continuous, high efficiency process for reducing sterol content in triglyceride oil by the steps providing a shell containing a support surface. The shell further includes an oil inlet of triglyceride oil and an oil outlet receiving oil from the second end of the support surface, as well as a steam inlet, a steam outlet and an upward directed steam flow. The triglyceride oil is driven upward on the support surface with the upward directed steam flow as a rising turbulent film. Then, the sterol is allowed to transfer from the rising turbulent film of triglyceride oil to the flow of steam. Preferably, the support surface is a tube or tubes which are vertically oriented. The triglyceride oil from the process has a sterol content below about 0.030% or even below about 0.018%.
