Groundnuts oil extraction machine introduction :
We supply different oil pressing methods for oil seeds with different oil content. Generally, for peanut oil press processing, first
pre-press peanut to the reasonable level and then extract the left oil from pressed cake.
We can also make oil press processing design as customer's situation and requirements.
The Oil press machine for peanut mainly include 5 steps process as follows :
1. Cleaning process of Groundnuts oil extraction machine :
Use vibration cleaning sieve and magnetic selector to get better cleaning effect.
And This step is mainly to clean the big impurities,like the stone , big dust, iron etc .
2. Crushing Process of Groundnuts oil extraction machine :
This Process is mainly to crush the peanut , as the peanut is big ,it is not easy to press .
We must crush the peanut to 6-8 pieces. Then we need to peel. The rate of peel is about 90% .
3. Flaking Process of Groundnuts oil extraction machine :
After crush and peel ,we need to flake the crushed peanut , which make the cell wall of
peanut broken . And we flake the peanut to 0.55 mm thickness . Then it is useful for the oil extracting .
4. Cooking process of Groundnuts oil extraction machine :
After the flaker,we need to cook the flaked peanut, control the moisture at 5-7% ,
the temperature is 110-115degree .
5. Oil press process of Groundnuts oil extraction machine :
Adopt spiral oil press with high production capacity, which obtains the advantages of large production capacity, less power consumption,
low transportation cost and residual oil rate, the structure of dry cake is loose and uncrushable, and it is easy for solvent penetration.
Main economic and technical parameters of Groundnuts oil extraction machine
Power consumption |
36KWH / t |
Steam consumption |
280 kg / t |
Pre-pressed cake thicknes |
≤17mm |
Pre-pressed cake moisture |
≤4-6% |
Pre-pressed Residual oil |
≤13-15% |
Peanut oil solvent extraction machine after Groundnuts oil extraction machine
After pre-pressing process , the requirement of peanut cake : moisture is about 8%, the residual oil :18-22% .
Use solvent organic solvent through soaking or spraying contact methods to extract oil from the cake. There is only
less 1% oil content in meal after oil extraction machine .
Remark: The extraction workshop must be in a separate yard . This yard should be have at least 1.5 m
high brick wall all around ,the walls is 12 meters far from extraction workshop. Fire district : at least 30 meters
far from residential area, keep from fire.
Peanut oil refining machine after Groundnuts oil extraction machine
Peanut oil refining is according to the different usage and requirements, utilizing the physical methods and chemical
processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.
The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction,
will be pumped into oil refinery units to produce cooking oil at various grades.
These processes include neutralization (removing free fatty acid), degumming, decolorization (bleaching),
deodorization.Then you can get first grade groundnut/peanut oil .
Final production peanut oil by oil press, oil refinery process
Pure peanut oil is amber yellow and has a LDeet nutty flavor. Refined peanut oil is very light in color and is
devoid of impurities and allergens. Avoid off-smelling old stocks as the oil might have turned rancid.
Groundnut/Peanut oil has very good lipid profile. It has saturated, monounsaturated and polyunsaturated
(SFA: MUFA: PUFA= 18: 49: 33) fats in healthy proportions.It is one of the stable cooking oils ;
having a long shelf life.
Packaging & Shipping
Packing : Packed by the protect film inner, water-repellent plastic outside. The wood packing is necessary if send by less than a container.
it will fixed by steel rope in the container.
