oil refinery equipment
Details of pre-treatment plant
a. Cleaning device:remove the raw material peanut in various impurities, such as: iron,
stones, clump, such as the plant leaf, clean up till impurity content does not exceed 0.2%.
b.Crushing machine: peanut is crushed into 6-8 pieces. In order to meet the requirements
of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.
c. Softening process:the purpose of softening is to adjust the moisture and temperature
of oil, and make it soft.
d.Flaking process: rolling raw material into flakes, and the purpose is to increae surface
area, destroy the peanut cell tissue, shorten the way of oil out from cake.
e:Cooking process: use steam cooking, inject direct steam and cook the flakes to meet the
requirement of oil press.
f.Pre-press:press the flakes to leave about 16%-18% in the cake. The cake will go to extraction
process.
g.Second oil press:Press the cake till the oil residue is about 5%.

Solvent extraction section introduction
Requirements for extraction cake ,steam ,water. electricity etc.
a.Adopting negative pressure evaporation can ensure excellent oil quality
b.Extraction system is highly adaptable,and can adapt to different oilseeds;
c.Unique exhaust gas absorption systeLD ensure good absorption effect;
d.Full enerLD-saving design utilize heat enerLD for many times and saves steam consumption.

4. Refining Process of oil press machine price
Degumming and deacidification:The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the edible oil. One is chemical way, the other one is physical way.
The chemical way is using NaOH to react with acid.
This way is suitable for the capacity of 5-30T per day.
The physical way is using steam and centrifugal to move the acid.
This way is used for capacity from 30-2000T per day.
Decolorization:This step is used to adjust the color of the oil. You can control the color of the edible oil according to the requirement of your market.
Deodorization:The function of this step is to move the special smell in the oil. This is an important standard for refined edible oil.
