Dry Fractionation Plant
The SPEC dry fractionation process is designed to separate palm oil into two fractions, Olein and Stearin, without the addition of chemicals or solvents. Same plant can be used for producing super olein and palm mid fraction of varying cloud point and melting point. The 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 and Advantages of Dry Fractionation
- 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.
