Dry fractionation of RBD palm oil

Dry Fractionation of RBD Palm Oil  
Dry fractionation of RBD palm Oil also called dry fractionation of rbd(
Refined, Bleached, and Deodorized) palm oil. The Henan Doing dry fractionation process is designed to separate palm oil into two fractions, Olein and Stearin, without the addition of chemicals or solvents. Same palm oil  fractionation plant can be used for producing super olein and palm mid fraction of varying cloud point and melting point.

The dry fractionation process includes :
• Preheating the feed stock to give a homogenous mass with nil solids.
• Crystallisation under preset controlled conditions of temperature & agitation to form stable, uniform sized filterable crystals.
• Filtering on membrane press filter (or Rotary Drum Vacuum filter) to separate the solid/liquid fractions.

Main Features & Advantages of Dry Fractionation of RBD Palm Oil
• Combines all operations, and monitors from a fully automated centralized control station.
• Easy to operate, requires minimum supervision.
• Good flexibility. Wide range of process applications possible.
• Feedstock can be crude, semi refined or fully refined palm oil.
• Suitable for both single or double fractionation.
• Minimum operating costs.
    - Low utility consumption
    - Low maintenance costs
    - No oil losses
    - No pollution problem
• Product quality.
    - Good crystallization repeatability, yielding consistent product quality
    - High olein yields
    - Low olein cloud point, with improved cold stability, Cloud point as low as 2 °C with iodine value of
      65.0 can be obtained
