Hydration Deguming & Alkali Refining Deacidification Process
Neutralization: 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°C) suitable for centrifugal separation to remove the phospholipids, Auxiliary Machine For Oil PressA and other impurities in the crude oil. Then the oil goes to the washing process.

Washing: there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, and the waste water is discharged to the sewage treatment station.
Vacuum drying stage: there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.If you are interested in our company,please feel free to contact Ms. Myra for a quotation,(Tel/whatsapp:0086-18363092712, Email:[email protected],Skype:leaderfoodmachine2).You will get superior service,and Shandong Leader Machinery Co.,Ltd. produce Mature technology groundnut oil extraction with high quality, high performance and the best prices.

Continuous Refining Decoloring Process
The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, the mechanical mixing method combined with steam mixing will improve the decoloring effect.
The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C), and then goes to the bleaching earth mixing tank. The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.
The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam. The decolored oil enters into the two alternate leaf filters to be filtered. Then the filtered oil enters the decolored oil storage tank through the security filter. The decolored oil storage tank is designed as the vacuum tank with the nozzle inside, so as to prevent the decolored oil contacting with the air and influencing its peroxide value and color reversion.

press operation priciple:

When oil press operating, the prepared materials enter the pressing chamber from the hopper and then move forwards by the rotating of pressing screw and is pressed under the high-pressure condition in the chamber, friction between material and chamber will be created, which also created friction and relative movement among material particles, on the other hand, root diameter of the pressing screw carries larger from one end to the other. hence, when rotating, it not only pushed particles moving forwards but also turns them outwards as well, meanwhile, particles adjacent the screw will rotation along with screw’ rotating, causing every particle inside the chamber to possess different speed, therefore relative movement among particle creates heat which is necessary during manufacturing. because of helping protein change property, damage colloid, increase plasticity, decrease oil’s elasticity, resulting in high oil productivity.

Solvent Condensation & Recovery Process

Solvent condensation system combines with evaporation system closely, and evaporative condenser and steam stripping condenser all work under negative pressure. Non-condensable gas enters the energy saver from the shell of the first evaporator. In energy saver, non-condensable gas exchanges heat with condensate from the evaporative condenser. Finally, the condensate temperature discharged from energy saver is increased, and the solvent separated from water goes to solvent holding tank. The high temperature makes it unnecessary to be reheated for the recycling, so as to save energy.

Non-condensable gas from energy saver enters desolventizing condenser, in which a great deal of gas is condensed, and the tail gas is discharged into the final condenser. The solvent gas from the extractor enters extraction condenser, and the non-condensable tail gas enters the final condenser. For the free gas in final condenser, diversion box, holding tank, underground solvent library and miscella tank, cool them with low-temperatured cold water to recycle most of solvent gas. The tail gas with little solvent goes to paraffin recovery process.

Negative pressure evaporation groundnut oil extraction

Miscella Vacuum Evaporation Process:

The liquid from the extractor is the miscella containing grease and oil, which can be separated out according their different vaporization temperatures. Our company mainly uses vacuum evaporation technology, and it can reduce solvent leakage and consumption. The separated solvent vapour is cooled and recycled back to the extractor for reuse, which can improve the solvent efficiency.

Vacuum Evaporation Advantages:

1. Vacuum evaporation features high efficiency, thorough de-solvation and low solvent consumption in crude oil.

2. Use the second steam of desolventizer toaster and remaining steam from steam jet pump as the heat source of the first steam, which can save energy, reduce the condenser configuration area and save investment.

3. Due to the low temperature of the steam, the crude oil features light color, good quality and low residual solvent.
