Dry Fractionation Plant, Dewaxing Plant & Winterzation Plants
palm oil fractionation process mainly include crystallization and fliter.Palm oil fractionation goes through the control of palm oil cooling and crystallization to make separation of palm oil into low melting point liquid (soft fat) and high melting solid (sterin).
The crystallization process follows in the crude palm oil refinery process. This process involves the removal of high-melting glycerides that would cause the liquid oils to become viscous and cloudy at room temperatures.
There are three most important factors: time, agitation and temperature. Low temperatures will cause the components to separate due to supersaturation while formation of smaller crystals will be facilitated by agitation. With gradual decreases in temperatures, longer crystals will be formed with time.

SINODER offers a wide range of batch & continuous Dry Fraction Plants.
 
Most of the natural oils & fats have only a limited applications in there original forms as a consequence of there specific chemical composition. In order to widen there uses the oils goes through variety of modifications, Fractionation is one of them.
 
Fractionation is the fully reversible modification process. It is basically a tharmochemical separation process in which a multicomponant mixture is physically separated in to two or more fractions with distinct physical & chemical properties. The can be based on a difference in solidification, solubility, or volatility of different compounds.
 
SINODER”s Fractionation plant is a custom design to allow you to achieve selective crystallization of different triglycerides in edible oil. This is plant you can count on producing stable & filterable crystals giving you a product to fit your standards and quality requirements.
 
SINODER’s Fractionation process system is designed to process crude, pre-treated or RBD palm oil. The process is divided in few steps as below.
Feed oil heating
Crystal formation under controlled cooling
Crystal growth
Crystal maturation
Filtration

Process Description
 
Dry Fractionation is a process to separate vegetable oils such as palm oil into two fractions, Olein and Stearin, by the crystallization properties of the oils. A typical dry fractionation plant consists of Crystallization Section and Filtration Section.

Crystallization Section
 
Preheated RBD palm oil is fed into the SINODER crystallizers and then cooled in a controlled environment to form crystals. The cooling sequence follows a defined program using PLC or programmable controllers. The slurry of crystals and oil is then pumped to the fractionation filter for separation of the solid crystals from the oil.
 
Filtration Section
In the filtration section, an automated membrane filter press is usually used for filtration of oil slurry to separate the stearin crystals from the liquid olein. Stearin is retained as filter cake while olein passes through the filter as filtrate. Olein yield is maximized by squeezing the stearin cake through inflation of the membrane with air or liquid.
 
Palm Oil Crystallizers


Features
 
At the heart of the dry fractionation process is the industry-standard SINODER crystallizers. A result of years of studies and continual enhancements, the SINODER crystallizers are hallmark of good and robust design.
 
With multiple sets of double-layered cooling coils surrounding a multi-impeller agitator, optimally arranged in a vertically orientated tank, the SINODER crystallizer is designed to provide optimal heat transfer efficiency and thermal homogeneity within the oil while maintaining minimal disturbance to crystal growth.
 
These crystallizers, together with SINODER’s experience and extensive database of cooling programs, can be tailored to produce different highly filterable crystals to suit various customer-specific fractionation requirements. Combined with vast in-depth knowledge of filter press performance, SINODER is able to provide specific fractionation solution meeting customers’ requests.
 
Repeatability
With higher tolerance to feed stock variation, the same cooling program can be used in our crystallizers with minimum fine-tuning to achieve consistent results.
 
Flexibility
The same crystallizer can be used for both the first or second fractionation processes to produce normal olein or super olein with lower cloud point; or further fractionation of stearin to produce tailored products.
 
Efficiency
Double layer coils are grouped in multiple sections to achieve optimum cooling efficiency. Furthermore, the agitation is varied by a frequency inverter during crystallization to homogenize the slurry with minimum disturbance to the process.
 
Minimum Operating Cost
Utilities costs are reduced using cooling water for pre-cooling during crystallization, thereby reducing the load on the water chiller. In addition, there is no chemical dosage, no oil loss and no pollution as in wet fractionation processes. Absorption chillers may be adopted when feasible to further reduce operating cost.
