Rice Bran Oil Machine

The whole rice bran oil machine 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

rice bran → magnetic box → separator → quenching and tempering → bulking machine → drying → to extraction 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 migLD 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). Bulking 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

solvent

↓

extractor → mixed oil → 1st and 2nd evaporation → stripping tower → crude oil

↓

Wet meal → DTDC toaster → rice bran cake

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

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

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.
