We are professional sunflower oil
making machine manufacturer, Big scale sunflower oil
plant contains three workshops:sunflower oil press, sunflower
oil extraction and sunflower oil refining .Sunflower oil making
machine price is depending on the capacity you
required.
Process
of sunflower oil making
machine
1. Sunflower oil
pre-press process
First, using
magnetic roller , destoner and cleaning machine to remove metals,
small stones , impurities from sunflower raw seeds.
Second, using husking machine to
remove husks, separating screen to separate husk and sunflower
kernel , here separating screen must not separate
completely uf not it will be too slippery for oil pre-
press.
Third, cooking
sunflower seeds ready for oil pre-press
Fourth, pre-pressing
sunflower seeds. here only pre-press part of sunflower oil , oil
residue inside cake (about ****6%) will be extracted in oil
extraction process.After pre-pressed, the crude sunflower oil will
be delivered directly to sunflower oil refining , and pressed
cake to oil extraction.
2. Sunflower oil extraction
process
First, using solvent to extract oil from sunflower
oil cake inside oil extractor, final products are mixed oil
and wet meal
Second, the mixed
oil will pass through three evaporators to make solvent inside
transform into gas , and solvent will be recovered through
condensers and reused. These three evaporators are not with
same size , the first evaporator is bigger than other two because
there are more solvent inside mixed oil in the beginning . After
evaporated, we will get crude sunflower oil ready for oil
refining.
Third, the
wet meal will be delivered to desolventizer to dry and be separated
with solvent . The dry meal will be packaged for sale as animal
feed.
Note: Sunflower oil extraction
is more and more important in oil processing , because oil residue
inside meal is less than 1% much less than oil residue inside cake
without extraction.
3. Sunflower oil refining
process
First , hydrated degumming, mainly is
to remove phosphatide inside crude sunflower oil in order to reduce
oil loss and improve quality of oil .
Second, alkali
refining, using alkali to neutralize free fatty acid with
by-product of soapstock ,which is used for making soap.
Third,
decoloration using bleaching clay to absorb darker colorant
inside crude oil.
Fourth, deodorization
is using high temparature to remove the impurities with bad smell
.
Fifth, dewaxing is
using low temperature to freeze wax inside refined oil and then
separate wax with vibrating screen.
