Edible oil refining Sunflower oil pressing machine, sunflower oil dewaxing machine for sale includes a series processing procedures as degumming, neutralization, bleaching, deodorization and winterisation. In general there are two methods of vegetable/edible oil processing, one is physical refining and the other is chemical refining. However, no matter what kinds of reining methods Small Coconut Oil Mill Machinery, Shandong Leader Machinery Co.,ltd. are all done with the help of various oil processing equipment and machinery, and are used to refine almost all kinds of oil extracted from oil seeds like sunflower seeds, peanuts , sesame seeds, and soya bean seeds etc.
Main Steps of Edible Oil Refining: Small Coconut Oil Mill Machinery Crude Oil Degumming: In this step gums in crude oil are removed by hydration with the help of phosphoric acid.Neutralization: In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.Deodorization: Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.Dewaxing (necessary for cold areas)Some kinds of oil like sunflower, maize germ or corn oil have waxes inside, if these Shandong Leader Machinery Co.,ltd. impurities are not removed, the oil will freeze easily under low temperature, thus effecting oil quality and appearance. so this process is necessary in extremely cold areas.

Product Description
What kind of crude vegetable oil can be refine?
Crude soybean oil, palm oil, palm kernel oil, sunflower oil, canola oil(rapeseed oil)
,peanut oil,
sesame oil, conttonseeds oil etc.
The main part of refining.
Hydration Deguming & Alkali Refining Deacidification
The crude oil is output by the oil feed pump from the oil tank, and next enters the crude
oil heat
exchanger to recover part of heat after metering and then is heated to the required
temperature
by the heater. After that, the oil is mixed with the metered phosphoric acid or citric acid
from
phosphate tank in the gas mixture (M401), and then enters the conditioning tank (R401) to
make
the non-hydratable phospholipids in oil change into the hydratable phospholipids.
Add the alkali for neutralization, and the alkali quantity and alkali solution concentration
depend
on the quality of the crude oil. Through the heater, the neutralized oil is heated to the
temperature (90℃)
suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in
the crude oil.
Then the oil goes to the washing process. 
Bleaching
In normal situation , there is pigment in the crude oil , we need to using the active clay
to absorb the
pigment away , after 20 mins , we use the vibrating filter to filter the waste clay away .
If you want
to get light color oil , you need to add more active clay . That is mean , the customer can
accord to his
requirement to control the oil color. This process is carried out under the vacuum
condition.
Deodorization
Usually ,there are some odors in the crude oil , it affects the quality of the edible oil .
About our
refining process , we usually use the direct steam to take odors away in the vacuum
condition .
General speaking there is about 0.5% water in the alkali refined oil, in the deodorization
pot,
thetemperature is very high , it also can finish the dehydration section.
Filtering
This process can remove off the small amount of unsettle gum soluble impurities in the
degummed
oil, after oil dehydrate cooling (60 °C), filtering again, to ensure the product oil
quality. Then pumping
the final oil into the oil tank.
3. Main section
(1) Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.
(2) Decoloring section: used to remove off pigments, bleaching oils and grease dehydrate.
(3) Deodorizing section: to remove off the odor components in oil.
(4) Dewax: used to remove off the wax in the oil, in order to get the high quality oil.
(5) Heat-transfer oil stove: supply each device production needing heat energy, temperature
reach above 280C.
(6) Steam generator: produce the needing steam for de-odoring and distillation.
(7) Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree
can reach above 755mm Hg.
(8) Press filter: filter clay, filter out clear oil.
(9) Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.

The purpose of Neutralizing Vegetable Oils Small Coconut Oil Mill Machinery is to remove Free-Fatty Acids (FFAs). Traditionally, FFAs are treated with caustic soda (NaOH). The reaction produces Soaps which are separated from the oil. Because Sunflower oil pressing machine, sunflower oil dewaxing machine for sale trace amounts of soaps remain in the oil, the oil is either washed with water or treated with Silica.Shandong Leader Machinery Co.,ltd. Some processors prefer not to perform caustic neutralizing. Instead, they prefer Physical Refining in which the FFAs are evaporated from the oil under high temperature and vacuum. This Sunflower oil pressing machine, sunflower oil dewaxing machine for sale process can be combined with deodorization step described under FFA stripping.Physical Refining process Sunflower oil pressing machine, sunflower oil dewaxing machine for sale is preferred because (a) it does not produce soaps; (b) it recovers fatty acids that provide better cost recovery; (c) there is smaller yield loss compared to caustic refining—especially for oils with higher FFAs; and (d) it is a chemical-free process.
