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 China quality equipment cotton seeds oil press equipment 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.

What is Refining?

The crude oil obtained either from expellers or solvent extraction plant containimpurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage. The process of removing these impurities is called refining.

The classical alkaline refining method usually comprises the following steps:

Step 1.Degumming with water to remove the easily hydratable phospholipids and metals.

Step 2.Addition of a small amount of phosphoric or citric acid to convert the remaining non-hydralable phospholipids (Ca, Mg salts) into hydratable phospholipids.

Step 3.Neutralising of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing out of soaps and hydrated phospholipids.

Step 4.Bleaching with natural or acid-activated clay minerals to adsorb colouring components and to decompose hydroperoxides.

Step 5.Deodorising to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorisation is essentially a steam distillation process carried out at low pressures (2-6 mbar) and elevated temperatures (180-220°C).

For some oils, such as sunflower oil or rice bran oil, a clear table product is obtained by a dewaxing step or crystallization of the wax esters at low temperature, followed by filtration or centrifugation.

The alkaline neutralisation process has major drawbacks, the yield is relatively low and oil losses occur due to emulsification and saponification of neutral oil. Also, a considerable amount of liquid emuent is generated. The soaps are generally split with sulphuric acid to recover free fatty acids along with sodium sulphate and some fat-containing acid water steam.

Craft features:

1.Continuous alkali refining shortens contact time between oil and lye,reduces

greasesaponification,lowers refining consumption,and improves efficiency.

2.Decolorization adopts technology of combining premixing and steam mixing

bleaching,which improves bleaching efficiency,saves consumption of bleaching clay,and

it's simple and convenient to operate;and negative pressure state avoids oxygen in the

air from contacting with hot oil,thereby ensuring oil product quality,inhibiting acivalue

to rise again,and lowering peroxide value.

3.Deodorization adopts new type continuous deodorization equipment which is

applicable for deacidification and deodorization of plant oil with high acid value and

low-resin content,the actual production proves its most obvious advantages are strong

deacidification ability,excellent hot bleaching effect,high refining rate,good oil quality

and so on.

4.The process has multiple heat exchange,which makes full use of the heat energy

system,effectively reduces steam consumption,and also has the advantages of adjustable

production process,flexible operation,high automatic degree,environment sanitation and

so on

Quality Requirements of Crude Oil

1.Moisture and volatile matter of crude oil: 0.25% max
