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.

How to Get Edible Oil from Oil Press Machine
Edible oil is a major part in our daily food consumption. Usually edible vegetable oil is obtained by oil pressing or oil extraction method. Oil press processing equipment always adopts physical pressing to press oil out of oilseeds. Oil extraction processing equipment uses chemical principle, using edible grade solvent to extract oil from pretreated oilseeds. Oil extraction combined with oil refining is considered as the most advanced oil processing technology.
How to get oil from crude oil
Whether the pressed oil or extracted oil cannot eat directly, it is called crude oil. For instance, there are impurities contained in crude oil, including raw material, oil pressing process or oil extraction process. Some impurity is harmful to human body health. For example, gossypol in cottonseed oil needs to be removed in order to get edible standard oil.
Test of finished edible oil quality
About quality of edible oil, there has developed a series of indicators, known as the national standard. Various types of oils have corresponding standard, generally containing color, smell, transparency, soap-containing amount, insoluble impurities, acid value, peroxide value, and the residual solvent indicator amount and other projects. The acid value, peroxide value and solvent residue is mandatory targets of national edible oil. All indicator approval oil finally reach edible oil standard.
Finished edible oil can be divided into four classes. For instance, first class edible oil, such as salad oil, no better getting from oil pressing or oil extraction crude oil, should be processed into high quality standard edible oil without color, small and odor. The solvent residual quality should be shown of no indicator.
Finished edible oil can only be processed through alkaline refining, decolorization and deodorization until getting refined edible oil. The finished edible oil after edible oil refining processing equipment has no containing of impurity, national standard approval, and finished product can be eaten directly for cooking.

How to Get Edible Oil from Palm Oil Refining Machine
Palm oil is the second largest edible vegetable oil in the world. As the result of low cost in both palm tree planting and low oil price, palm oil as edible oil has obvious competitive advantages on world’s market. Palm oil after physical oil pressing process is only crude oil, which needs a series of palm oil refining process in order to achieve edible oil standard.
The purpose of palm oil refining machine is to remove impurities in order to reach edible oil standard. Palm oil refining machine covers a series of processes including crude palm oil, degumming, decolorization, deodorization and fractionation. The complete processing line of palm oil refinery contains hydration degumming, alkaline neutralization, steam distillation deacidification, active carbon absorbent activated clay or high temperature vacuum deodorization while removing low boiling volatiles.
What is major process of crude palm oil refining machine processing line?
Crude palm oil filtration
The crude palm oil should be filtrated in order to remove suspended particle impurities and other impurity for further step palm oil processing.
Degumming
Crude palm oil degumming removes impurities of phospholipid, sugar, protein mixture, trace metals and other impurities. The quality of raw material oil greatly determines the quality of the final product. The gum in raw material crude palm oil is an important factor in the quality of grease.
The advanced degumming technology can remove gum completely in crude palm oil. The centrifugal separator can make the best degumming result in order to obtain the highest quality refined palm oil.
Neutralization
Neutralization deacidification is playing extremely important part in palm oil quality and price. Both physical and chemical methods are available to make high efficiency deacidification. Physical palm oil refining machine adopts stripping distillation method as preferred palm oil refining process. Chemical palm oil refining refers to neutralization with sodium hydroxide and free acid in crude oil deacidification to produce soap and water.
Decolorization
Decolorization can remove pigment in oil, but also serve to reduce the phospholipid content, peroxide value, and the role of the amount of soap containing metal ion content, thereby improving oil color, flavor and oxidative stability of hydrogenated oil further oil refining, deodorization.
Deodorization
In the deodorization process, in addition to complete deodorizing purposes, palm oil refining machine process should focus more on the current unit operation strive to achieve at a low temperature, short time, preventing the generation of trans fatty acids, tocopherols to reduce the loss, reduce the polymerization and reduce the vitamins decomposition.
The palm fruit oil after fractionation can obtain vegetable palm oil with high edible oil standard. We have rich experience of palm oil processing machines from palm oil press, crude palm oil refining and palm oil fractionation with mature technology of design, manufacture and installation. The palm oil refining machine has just help users to get the highest quality palm oil at affordable price.
