Palm
oil refining technology refers to conversion of crude palm oil to
refined oil involves removal of products of hydrolysis and oxidation,
color and flavor. Adopts scientific designed palm oil refining machine
process line including degumming, dea-cidification, decolorization,
blenching, deodorization to obtain high quality refined palm oil.
We can offer turnkey palm oil refinery plant solutions from plant layout
design, machinery manufacturing, onsite debugging and installing.
The unique and best quality of Palm is that it produces two types of oil: – Palm Oil and Palm Kernel oil.
Palm oil is extracted from the flesh of the Palm fruit and Palm Kernel
Oil is extract from the seeds or kernel of the Palm fruit.
The Palm Oil is extracted from the fresh Palm fruit flesh by pressing
& centrifugation. The Palm Oil extraction is to be done with the
fresh Palm fruit to avoid the deterioration of Palm Oil. Hence, the
countries cultivating Palm Oil are extracting themselves to avoid its
deterioration. The crude Palm Oil comes out as yellow red or dark yellow
in color and the taste of the crude Palm Oil is sweet.
The Crude Palm Oil Extracted contains the unwanted impurities which
effect adversely on the physical appearance, quality, oxidative
stability, shelf life of the oil. In order to remove the above
impurities, the oil goes to the refinery plant in order to receive the
RBD Palm Oil (Refined Bleached & Deodorized).
After refining of the Palm Oil, the RBD oil goes to the fractionation section in order to get the Palm Olein and Stearin.
Refining is the process in which we remove the undesirable impurities from Crude Palm oil as mentioned below.
Phospholipids
Free fatty a-cid
Coloring pigments (Carotenoids)
Moisture, oxidative material, metal impurities, and water soluble impurities (glycerol, Phenols, Sugars).
The term refining includes the removal of above impurities in order of
increasing shelf life and quality of Refined Vegetable oil.
Palm Oil Refining Plant
Palm oil refining consists of the following sections
Bleaching
Deodorisation / De-a-cidification
Fractionation
Generally, refining process is necessary steps for the production of
edible oils and fats products. The qualities of the finished product
that need to be monitored are flavor, shelf-life, stability and color of
the products.
Refining of crude vegetable oil is done by two methods: Physical
refining and chemical refining. During refining of crude palm oil, FFA
are removed in order to achieve the FFA content of up to 0.1 % max.
Physical refining generally has a lower environmental effect than chemical refining.
Physical Palm Oil Refinery Plant Vs. Chemical Palm Oil Refinery System
Crude palm oil can be processed by either physical refining
(distillative neutralization, steam stripping) or chemical refining
(alkaline refining) to produce RBDPO and NBDPO. RBDPO refers to refined,
bleached and deodourised palm oil, while NBDPO refiers to neutralised,
bleached and deodourised palm oil.
In Physical refining the role of deodorizer is to strip free fatty a-cid,
odor removal and heat bleaching to cut the remaining color in bleached
oil.
In chemical refining the role of deodorizer is odor removal, heat
bleaching to remove the remaining color and recovery of fatty a-cid
distillate. The steam is injected in each compartment of our deodorizer
so that intimate mixing of oil and steam takes place. This arrangement
of steam pipes makes deodorization process more efficient.
Dry 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.
Palm oil Fractionation plan 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
After the Deodorization section the oil is first cooled by cold
Fractionated oil for maximum regeneration of heat Palm Oil Fractionation
machine. Then the same oil is cold by cooling tower water up to 40˚C to
45˚C.
Then this oil is cooled by outgoing chilled fractionated oil from the
filters. This oil is then chilled to fractionation temperature in the
Crystallizers.
In the crystallizer proper residence time is given with maintaining the
temperature of the oil, which results in formation of wax / stearin
crystals and residence time, will give proper growth to the crystals.
The step cooling is followed in the crystallizer for the complete
maturation of the crystal which increases the efficiency of the Palm Oil
Fractionation Plant. The oil is cooled with the tempered water and then
it is further cooled to the final fractionation temperature by the
Chiller water.
After obtaining the desired temperature inside the crystallizer the
mixture is then feed to the Filter Press for the separation of Stearin
from Palm Olein. The recovery of the Palm Olein does also depend upon
the kind of filters used.
The complete operation is controlled by Automatic Electronic Panel (PLC
). we are one of the leading Palm Oil Processing Plant
manufacturers/Palm Oil Fractionation Machine suppliers in China and
abroad.
