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.
