Rice bran oil machinery Pretreatment and Press process:

Cleaning and separating—-steaming—-cooking—-pressing—-filter—-crude oil

Each step purpose:

A. Cleaning and separating: Remove the broken rice and other impurities, that can guarantee the rice bran oil yield. This process mainly to remove the impurities like iron, sand, broken rice and others. If the impurities exist in the rice bran, it will affect the machines operation. And make the crude oil impure, then largely affect the rice bran oil refining process.
The cleaning method mainly includes screen and magnetic separation.

B. Steaming: In order to soften the crude fibre and conglomerate the protein, break the cell wall, small oil drip can gather into the big oil drip, so that the oi can be easily out. This process namely soften the rice bran, making the bran cooked. As the rice bran is low oil content and low moisture content, so it has to through steaming to adjust its moisture and temperature to a suitable level that can increase the rice bran elastic-plastic, break the cell wall and oil easily out when pressing.

Condition: rotate speed: 40

C. Cooking: Lower the moisture in the rice bran, so that oil can be easily out. This process has the same purpose with steaming, aiming to make the oil out easily, the difference is just lower the moisture to 5~7%, to much water content will affect the rice bran oil quality.

Condition: stir constantly
temperature: 125°C
time: 20~30min
moisture lower to:5~7%.

D. Pressing: This is the oil out process, the cooked rice bran will be sent to screw oil press machine through the screw conveyor. After pressing, we can get the crude rice bran oil.

Condition: temperature: 80~90°C
time: 3~5min

E. Filter: Filter the crude oil with canvas or double layer cloth in the Plate-fram filter, control the temperature to 70°C, then the crude oil will be sent to the refining process.

Condition: temperature: 70°C

Refining process of rice bran oil machinery:

Crude oil—-degumming—-deacidification—-decoloring—-filter—-deodorizing—-fourth grade oil
Crude oil—-degumming—-deacidification—-decoloring—-filter—-deodorizing—-dewaxing—-degrease—-first grade oil

Introduction of the whole process:

A. First send the crude oil into the mix reactor with certain quantity water and acid, after well blended send into the centrifugal separator and then separate the oil sediment.

B. Second send into another mix reactor, adding certain concentration alkali and well neutralization reaction. Separate the soap stock through the centrifugal separator.

C. Now wash the crude oil with light alkali and water, washing out the residual soap stock.

D. Third send the oil into the bleaching tower, well blended with certain quantity clay, under the certain temperature, time, vacuum condition, the clay absorb the colorful substance and other impurities. Then separating the waste clay through the centrifugal separator.

E. At last send the oil into deodorization tower, under the certain temperature and vacuum condition, deodorizing the oil through steam stripping. Then get the fourth grade oil.
