PROCESS FOR DRY FRACTIONATION OF A PALM OIL OLEIN

摘要

A process for dry fractionation of a palm oil olein (POON) is disclosed, the process comprising the steps of providing the palm oil olein (POON) as a melted palm oil olein (MPO), cooling the melted palm oil olein (MPO) to obtain a supersaturated palm oil olein (SSPO), subjecting at least a part of the supersaturated palm oil olein (SSPO) to ultrasonic treatment, crystallization, in a crystallizer (CRS), of the supersaturated palm oil olein (SSPO) having been subjected to ultrasound to obtain a palm oil olein slurry (POS), separating the palm oil olein slurry (POS) to obtain a palm oil mid fraction (PMF) and a super olein fraction (SOF). Also, a fractionation system (FRS) and a dry-fractionated non-detopped palm oil mid fraction (PMF) are disclosed.
