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 Rice Bran Oil Extraction Machine 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.

Specifications

China Rice Bran Oil Extraction Machine

The whole rice bran oil solvent extraction plant contains three workshops: Rice bran pretreatment workshop, rice bran oil extraction workshop and rice bran oil refining workshop.

1. Craft flow for rice bran pretreatment workshop
Main Equipments of rice bran pretreatment workshop:
1). Rice bran: It's the shell and embryo of the rice. The oil content in the rice bran is about 18-22%. The rice mill can supply the rice bran.

2). Magnetic box: Clearing the iron impurity which might be in the rice brain. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect.
3). Separator: Removing the chaff and broken rice in the rice bran, in case of they will influence the oil yield and the desolventizing of wet meal in the next process.

4). Quenching and Tempering: It is the process of preheating so that to improve the temperature of the rice bran before puffing.

5). Extrusion machine: This machine can make the rice bran becoming porous columnar structure from the original pulverized state. This is good for the oil extraction part and improve the oil yield.

6). Drying: The moisture of rice bran comes from the bulking machine is too big and the temperature is too high for direct extract, so the rice brain are usually dried and cooled by plat dryer.

2. Craft flow for rice bran oil solvent extraction workshop
Main Equipments of rice bran oil solvent extraction workshop:
1). Solvent pumps: Continuously spray solvent to the rotary-typr extractor.

2). Roary extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).

3). DTDC toaster: Used to separate the solvent from the wet meal.

4). Miscella tank 1st: Pump the miscella ( oil with solvent) into the miscella 1st, then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline water, at last the reactant precipitate, reaching the goal of purifying.

5). Miscella tank 2ND: The purified miscella will be pumped into it.

6). Miscella stripping: It will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.

7). Condensers: Used to cooling the solvent gas separated from the wet meal and miscella for recycling.

3. Craft flow for rice bran oil refining workshop
The rice bran oil is special, so it's difficult to become 1st grade rice bran oil. We have rich experience in rice bran oil refinery and can help you getting the 1st grade rice bran oil.
Main Process of rice bran oil refining workshop:
1). Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the rice bran 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.

2). Decolorization: This step is used to adjust the color of the oil. You can control the color of the rice bran according to the requirement of your market.

3). Deodorization: The function of this step is to move the special smell in the oil. This is an important standard for refined oil.

4). Winterization: This is special step for rice bran oil refining, because there is much wax in the rice bran oil. After move the wax in the oil, it can be liquid in a low temperature. This step also can improve the taste of refined rice bran oil.
