cold pressed peanut oil machine | groundnut oil press machine manufacturer for processing peanut oil
Product Description
peanut oil machine is a complete set of machine used for pressing peanut oil from peanut.we are the manufacturers of peanut oil press machine . We have been specialized in peanut oil press machine since 1967.
We provide turn-key service of peanut oil press machine including peanut oil press machine , peanut oil machine installation,person training, peanut oil machine tech consulting and peanut oil machine after sales.
Process for peanut oil production mainly as below
The complete peanut oil production process of our machine includes pretreatment,pressing,solvent extraction,refinery,these four sections to produce peanut oil up to standard of national first grade peanut oil and byproducts from the very beginning of cleaning.
1.pretreatment for peanut oil processing
This section could reduce the damage to the subsequent machine and get the oil seed at condition to extract oil.it is made up of these below process.
a.Cleaning process for peanut oil machine:
high efficiencyvibration screen to remove big or small impurity;
suction-type specific gravity stoner to get rid of stones or mud of the same size with the peanut;
magnetic selector to remove metal impurity;
aspiration system for dust remove;
b.Crushing process for peanut oil machine:
for good flaking and cooking, the peanut pieces should be uniform(4-6 pieces per peanut)
c.Flaking process for peanut oil machine:
after flaking would form 0.3m flake pieces. it aims to extract maximum oil in shortest time from the raw materials and let the residue in the meals be less than 1% during the solvent extraction section
d.Cooking process for peanut oil machine:
to break the peanut cell, make Protein denaturation and improve oil yield.
e prepressing is by physical pressure to squeeze the oil out
Expeller pressing is the method of extracting oil with a mechanical press that has been resulting in a more pure oil, higher in natural colors and flavors.
An expeller press is a screw type machine, which presses oil seeds through a caged barrel-like cavity. This machine uses friction and continuous pressure from the screw drives to move and compress the seed material. The oil seeps through small openings that do not allow seed fiber solids to pass through. Afterward, the pressed seeds are formed into a hardened cake, which is removed from the machine.
More than half of the oil is easily removed in this way, but perhaps 7% or 8% residual oil is left in the solids
2.Solvent extraction section for peanut oil processing.
In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less hp, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.
Extraction theory can be put very simply: we are trying to soak oil out of small particles or flakes of material with a solvent, usually hexane. The solvent has to travel into the particles, soften up and dissolve the oil, and the miscella (the solution of oil in the solvent) then must travel out of the particles and be washed away by still more solvent.
there are four more requirements will influence solvent extraction.
a solvent
b contact
c time
d temperature
3.Refinery for peanut oil pressing machine
process :deguming-------deacidification-------filtration------deodorization----dewaxing/fractionation----product oil
Process of deacidification:
1. Neutralization:
In neutralization which means deacidification process, the oil at a proper temperature is added in proper concertration of lye, goes into centrifugal mixer. For mixing, the mixture is sent into neutralization tank and stay for enough time. During this period, the lye will neutralize the FFA, form soapstock and are separated in neutralization separator. The formed soap stock also can absorb other impurities and pigments. To separate the oil and soapstock more easily, the mixture would be heated, to reduce the viscosity.
2.Washing:
The neutralized oil from the neutralization separator, still contain about 500ppm soap. to reduce the soap content, the oil would be added into about 15% hot water and to wash in the washing mixer. The hot water will absorb the soap and other impurities, then are separated in the washing separator
3.Vacuum-drying and dewatering
The oil from the washing separator still contains some water which is harm to oil stability. To remove this part water, the oil at a temperature of 110-120âC, are sent into Vacuum drying tower to dry the water. After this the oil will be pumped into decoloration process.
Process of decoloration
decoloration aims to remove the pigment and The residual soap etc. it includes:
1.decoloration
The oil firstly should be heated to 105âC.The heated oil then is sent to Vacuum bleaching tower. when the oil goes into the bleaching tower, it mixed with white clay via ratio mixer.
White clay transportation system is used to send the white clay on the ground to the storage tank on the top of bleaching tower.
The bleaching tower are divided into several floors, every floor is equipped with steam ejector which used to mix the oil and white clay. The rest soap, gum, pigment and other metal would be absorbed by the white clay too.
2.filtration
the mixed oil from bleaching tower would be pumped into the filter, and then goes into the secondary filter, here white clay and the solid impurities would be stopped, the bleached oil would be transferred to bleached oil storage for middle storage.
In this filtration system, there are 2 decolorizing filters, always one in filtering and another is emptying and cleaning. When the filter are in emptying and cleaning condition, the filter would be squeezed by steam, so most oil in the filter would be swept into bleaching oil tank, few oil mixed with waste white clay is sent into dirty oil tank. The filter cake have been dried by steam, the leftover oil and water gathered during the drying period are sent into the dirty oil tank too. Finally the dried cake on the bottom of the filter was poured into waste clay room via bleed valve by air vibrator.
The leftover oil in the dirty oil tank would be pumped into bleaching tower for reworking.
Deodorization section
The deodorizing aims to remove the FFA,small molecular substances,including
1.Gassing
The bleached oil are stored in bleached oil tank, this tank are designed to work in vacuum condition. From this tank, the bleached oil is pumped into deaerator, to release the gas into the oil.
2.Heating
The flow of the bleached oil is controlled by a controller, the oil is heated at a temperature of 250-260âc by a series of heat exchanger.
When the oil is heating in the final oil heater, here some low- boilling point FFA and volatiles would evaporate. The steam and liquid oil would go into the packing deodorizing tower from different entrances.
3Deodorization
The heated oil would be distilled in the flashing tower, storage tank and main deodorizing tower, the FFA and smell matters would be removed aftergasification
After refinery we would get high grade peanut product oil.

AAA1
Electronic system of this soy protein production line is the most advanced part of this machine, it is fully automatic, easy to operate, and there’s no special request to the operator, so this machine is particularly suitable for household and workshop.
3. Stainless Oil Drum
soy protein production line is put into the assembly of the press boring ,then it being droved up by the oil cylinder piston ,oil will outflow from the gap of press boring ,and then pass the oil drip pan to the drum for oil storage.
