What is the modern methods of extrating rice bran oil in factory?

Rice bran contents 15%-18% oil, which belongs to low oil content oil seeds. If using press way, there will cause waste. So in factory,  the mordern methods of exrating rice bran oil is puffing + solvent extraction method.

Rice bran and oil content

First, rice bran need some machines to process and into a better condition for solvent extraction. The puffing machine is one of them. The machines contains cleaning machine, moisture conditioning machine, puffing machine, drying machine. These machine can make rice bran reach the best condition for solvent extraction, and help extract maximum oil. The machines are as following picture shows:

Rice bran pretreatment machines

And then the pretreated rice bran will be sent into rice bran oil solvent extraction plant. Rice bran oil extraction process contains four steps: rice bran oil solvent extraction part, miscella processing part, wet meal DTDC system and solvent recovery part. It is a complete line of solvent extraction, which can also be used to produce soybean oil, groundnut oil, sunflower oil, palm kernel oil, etc.

Rice bran oil solvent extraction plant

Why should use the puffing + solvent extraction method to extract rice bran oil? Because it can make the oil residual rate less than 1%, and you can get more benefits. Henan Doing Company is one of professional manufacturer in China. If you want to produce rice bran oil, welcome you to contact us!

How to make rice bran oil in the rice bran oil production factory?

In the rice bran oil production factory, to make rice bran oil usually use puffing+solvent extraction technology, which is because the rice bran is easy to deteriorate in storage and its oil content is very low.

So firstly, you need four kinds of rice bran pretreatment machines: cleaning machine, moisture conditioning machine, puffing machine and drying machine.

Rice bran pretreatment machines

1. The cleaning machine is to separate the broken rice and rice bran.
2. The moisture conditioning machine is used to adjust the temperature and moisture of rice bran.
3. The puffing machine is to change the inner structure of rice bran, in order to make the leaching process more easily.
4. The drying machine is used to dry the puffed rice bran, and make it have much longer time to storage, about 10-15 days.

And then you need set up a complete rice bran oil solvent extraction plant.

How to make rice bran oil by rice bran oil extraction plant?

Rice bran contents 16%-20% oil, it is one of the three health oil recommended by WHO. Rice bran oil price is much higher than other normal oil. How to make rice bran oil by rice bran oil extraction plant?

Our team is willing to be your considerate consultant to help you extract the max oil from rice bran, and make the waste rice bran into fortune.

Rice bran oil pretreatment machines

The flow chart of rice bran oil production line is as following:
Raw material (rice bran) →magnetic separation →floury product separation →quenching and tempering →puffing(extrusion machine)→drying and cooling →solvent extraction plant →refining plant →dewaxing plant →high quality refined oil 

1. Cleaning:
To make rice bran oil, cleaning is the first step. Same with other oil seeds pretreatment process, rice bran needs cleaning section to remove mechanical impurities in rice bran to improve oil yield rate.

2. Puffing:
Puffing machine is able to destroy oil seeds cell completely with high temperature, high pressure, etc. Puffing is necessary part to make rice bran oil.

3. Rice bran oil solvent extraction plant:

Rice bran oil solvent extraction plant is similar with other cooking oil solvent extraction plant, including solvent extraction, desolventizer toaster, oil stripping, and solvent recovery.

4. Rice bran oil refinery plant with dewaxing section:
Same with other cooking oil refining plant, rice bran oil refinery plant includes degumming, deacidification, decolorization, and deodorization sections. What is different is rice bran oil need dewaxing section, because the wax content in rice bran oil is high, about 3% - 5%.

We have been specialized in rice bran oil extraction plant since 1967. If you want to

Do you know the main process of the rice bran oil production line?

Rice bran is rice processing byproducts, rice bran layer from the large Mi Maipi in preparation of oil, rice bran oil 15% -22%. Rice bran oil is a high quality edible oil, contain the growth of health promoting essential fatty acids, resistant to preserve the advantages of thermal oxidation, etc., is also known as "healthy oil", "nutrition oil." There are rice bran oil extraction process and rice bran oil refining process two parts.

Rice bran pretreatment machines

In rice bran oil production line, there are two: one is mechanical compression, the other is a solvent extraction method. This paper describes the mechanical compression.
Rice bran mechanical compression process: cleaning, steaming and roasting, make the cake, pressing, filtration.

Rice bran oil extraction process:

1. leaning: Available winnowing, screening and other methods to remove the broken rice bran and other impurities inside.

2, steaming and roasting: the bran directly into the flat-bottomed wok, the speed of 40 rev / min, the water is about 6.5% -7.5%, temperature 120 ℃, steaming and roasting time is 10 minutes. Or steamed rice bran into the vertical multi-wok, add water to make up to 25% moisture content, steaming and roasting 490-686.6 kPa pressure for an end to a temperature of 130 ℃, water content of 4% -5%.

3, to make cakes: steamed fried blanks made into bread machine spiral press into the cake. Make cakes faster.

4, press: 90 type or 95 type pressing machine press, when the press first fast-pressed, for about 3-5 minutes, then slowly squeezed until the majority of the oil is squeezed out and then carry on and drain, drain oil at high pressure booster pump to the vertex.

5, filter: The filter press with good hair bran oil on canvas or double white oil filter, the filter temperature control at 70 ℃. Squeezed out of wool bran oil, must be refined in order to eat.

And more information about rice bran oil solvent extraction process
