Rice Bran Solvent Extraction and Oil Refinery Plant

Rice bran is a kind of special oilseeds with quite low oil content, which is especially applicable to getting edible rice bran oil by one time solvent extraction and oil refinery process. Rice bran one time extraction needs to go through rice bran pretreatment and rice bran oil extraction processes. Rice bran pretreatment contains steam flaking, granulation and expansion. There are dry and wet puffing available. Rice bran oil extraction plant goes through a bit different oil extraction method, which pays more attention to rice bran extraction and wet bran desolventization process.

Rice bran oil extraction process obtains a kind of high acid value crude oil. The adoption of physical rice bran oil refining process has obvious advantages in increasing the rate of oil refining and economic aspects. Rice bran oil refinery process includes degumming, blenching, deacidification, dewaxing, degreasing. The key point is distillation deacidification, degumming and deacidification are especially important.
In practical applications, rice bran oil physical refinery is adjustable according to rice bran raw material condition, refined rice bran oil product quality grade, combined with chemical oil refinery to make free adjustment of finished rice bran oil.
The time rice bran oil has lower acid value, sometime rice bran passing through fresh treatment can control acid value of rice bran under 6mgKOH/g. This kind of excellent quality crude rice bran oil can also used chemical oil refining process to get high quality rice bran oil. There is no need to consider physical oil refinery process.

The adjustment of ordinary rice bran oil and high grade rice bran oil can make rice bran achieve high quality rice bran oil refinery condition. The available rice bran oil after physical oil refinery is available in quite low acid value and good oil color. The oil quality can reach first grade rice bran oil. The time users are processing high acid value rice bran oil, will get third or fourth grade rice bran oil.

One Time Rice Bran Extraction and Oil Refining Process

Low oil content of rice bran as a special fuel, it is suitable for extraction of crude bran oil. Rice bran extraction undergoes a pretreatment and rice bran extract two stages. Rice bran pretreatment contains three kinds of steamed fried, granulation and expansion. Both dry and wet expansions are selectable for users to make further process of rice bran oil solvent extraction.

Rice bran oil extraction process has a bit different extraction method from other bulk oils, which pays more attention to rice bran raw material extraction, wet meal desolventizing. Crude rice bran oil after solvent extraction has got high acid value, the use of physical refining process has obvious advantages in increasing the rate of oil refining and economic aspects. Physical rice bran oil refining comprises degumming, bleaching, deacidification, dewaxing, degreasing, the key step is a distillation deacidification. Degumming and bleaching vital to its pretreatment step. Rice bran oil physical refining process applications in the actual production level of product quality according to the requirements of raw wool bran oil and refined rice bran oil situation, combined with a comprehensive chemical refining process or production of refined oil products of various grades of regulation, made the best use of benefits.

Rice bran is a by-product of rice processing, has a high utility value. Crude rice bran oil is available with the help of solvent extraction process. Edible rice bran oil after rice bran oil refining process can make fully removal of all kinds of impurities. Rice bran has quite low oil content of 14% to 24%, it is very suitable for crude oil extraction with the addition of solvent. Since rice bran contains lipase, usually the acid value of crude rice bran oil is among 10 ~ 30mgKOH/g. However, the acid value of extracted rice bran oil from moldy rice bran or rancidity rice bran can reach as high as 40 ~ 100mgKOH/g. In order to make full control of high acid of rice bran oil, physical oil refining process is highly recommend in order to get high quality rice bran oil.
During one time rice bran oil extraction, rice bran should be processed through steam flaking, granulation and expansion. According to the special nature of the material rice bran, rice bran  oil process plant needs to be adjusted according to wet meal desolventizing technology and equipment.
Since crude rice bran oil is a high acid crude oil, traditional chemical oil refining method has comparatively weak points of improving fine rice bran oil refining rate and economic aspects. However, physical oil refining machine process can make perfect treatment of the problem of high acid value. Physical rice bran oil refining process has superior highlight in processing high acid value crude rice bran oil.
With the gradually mature rice bran oil processing technology and wide spread planting of rice, rice bran oil as a healthy oil is more and more accepted by consumers. One time rice bran solvent extraction and rice bran oil refining technology can also get wide prospect all over the world.

Rice Bran Oil Processing Plant In Bangladesh

Bangladesh has especially long history of rice plant and rich experience with rice processing and rice making products. However, rice bran oil, as a very new and popular project, has newly developed in Bangladesh. More and more rice plant people have begun to concentrating on deep processing of rice and make full use of rice in daily life. As a result, the most advanced rice bran oil processing plant has become very popular in Bangladesh in order to process first-grade rice bran oil with high safety standard and edible oil approval.

Rice bran oil processing plant is playing an especially important part in modern time edible rice bran oil production. Not the same as those of high oil content oilseeds, rice bran oil content is only 13% to 17%. Waste rice bran can be processed into first class rice bran oil through processing flow of rice bran expansion, rice bran oil extraction plant and rice bran oil refining process.
It is not an easy job to get high quality rice bran oil unless great efforts on research and development of the most advanced rice bran oil processing technology. Edible rice bran oil can be available after three major process as listed below:

After rice processing, the waste rice bran should be processed through cleaning, crushing, expansion process for convenience of further step rice bran solvent extraction. Because of low oil content, rice bran oil cannot be pressed out directly from rice bran. On contrary, rice bran is pretreated through expansion and extruding in order to get acquired shape rice bran cake. The expansion rice bran cake will make great convenience in further step solvent extraction since expansion can increase connecting area between rice bran cake and no. 6 solvent.

The pretreated rice bran cake is sent to rice bran oil solvent extraction plant by conveyors. In rice bran extraction plant, rice bran cake is fully immerged into no. 6 solvent in rotary extractor. Crude rice bran oil is available after evaporation and steam stripping, DTDC high efficient energy saving toaster. The unique configuration of tail gas recovery system can obtain perfect absorption result during the whole processing of rice bran oil extraction.

Rice bran oil refinery plant is the final step of obtaining first grade rice bran oil. In order to remove no.6 solvent exiting in crude rice bran oil, rice bran oil refining process machine is quite necessary to help users to get required quality standard rice bran oil. The adoption of electric control system assures the most scientific production of edible rice bran oil in Bangladesh.
