Main Equipments: 

1. rice bran: It’s one of main oil seeds from human. It’s used to make rice bran oil around the world.

  The oil content in rice bran is about 18%.

2. Magnetic box: Clearing the iron impurity which might be in the rice bran. The iron impurity will be harmful to the following machines, so we need take the iron impurities out. 

3. Cleaning: This parts have different size cleaning sieves to clean the different impurities. After going through this part, most of the impurities are moved from rice bran.

4. husking:this can help improve the oil yield from rice bran,and reduce wear to the machine.

5. flaking:  It is the process of making use of the mechanical action to flake the rice bran into flakiness. After flaking, the materials is becoming thiner thank before, it is good for absorb moisture and heat in cooking process , and it is much easier for getting rice bran oil in the oil press process.

6. Cooker: This machine can adjust the water content of the rice bran. It’s also good for the press and oil extraction section.

2.Craft flow for pressing of rice bran oil screw press 

Press: The press machine is used to take oil out of the rice bran . 

After pressing,we can get crude rice bran oil,and the oil residual in the cake is about 5-7%.

3. Craft flow for refinery of rice bran oil screw press 

Crude rice bran oil → degumming and deacidification→ decolorization →deodorization → refined  rice bran oil.

Main Process: 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 oil 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 rice bran oil.
