Rice bran oil processing plant

Specifications: 20T/D----1000T/D (daily processing capacity)

The whole production line contains three workshops: rice bran pretreatment&expansion workshop, rice bran oil extraction workshop and rice bran oil refining workshop.

Pretreatment Process:

Crude rice bran → cleaning → softening → expanding → drying → to extraction workshop

1.Screening:Removing the chaff and broken rice in the rice bran, in case of they will influence the oilyield and the desolvent of wet meal in the next process. In the process of puffing section, the general requirement of impurity is less than 3%, and the requirement of crude fiber is about 8%.

2.Magnetic separation :Clearing the iron impurity which might 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. As the rice brain particles are small and poor liquidity, the iron impurities are always be wiped off by the magnetic barrels installed in the feeding port.

3.Quenching and tempering :it is the process of preheating so that to improve the temperature of

the rice bran before puffing. After quenching and tempering the temperature will be controlled at 65--75 °C, and the moisture will be controlled at 10 ~12%. Thus, on the one side, it can increase

the output of the extrusion machine, and on the other side, it can improve the quality of the puffed rice bran.

4.Puffing the rice bran is injecting high pressure steam and high temperature water through the

extrusion machine, so that it can improve the temperature and moisture in the extrusion machine,and can also form the high pressure to process the rice bran. All these can make the the rice bran become porous columnar structure from the original pulverized state.

All these effectively passivate the activity of various of enzyme in the rice bran, and destroy the

fat layer structure, so that it will be easier for the oil yield.

5.Drying:The moisture of puffed material comes from the extrusion machine is too big and the

temperature is too high for direct leaching, the must be experience to process of drying and coo-ling, thus the moisture will reach 7%--9%, and temperature will reach 50--55°C. After puffing, the rice brain are usually dried and cooled by plat dryer.

Solvent extraction process:

solvent steam

↓ ↓

extraction → mixed oil → evaporation→ steam-stripping → crude oil

First, send the rice bran meal to the roary extractor, the meal will be fully soaked in the extractor by the solvent. Thus, the oil in the rice bran will be absorbed in to the solvent.

1. Solvent pumps: continuously spray solvent to the rotary-type extractor

2.Roary extractor: Spray and soak the pretreatment rice brain 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. LD: usd to separate the solvent from the wet meal.

4. Miscella tank 1st: pump the miscella (oil with solvent) in to the miscella 1st , and then add 10% saline water to it. The phospholipid and impurities in the miscella will react with the saline wter, at last the reactant precipitate, reaching the goal of purifying.

5. Miscella tank 2nd: the purified miscella will be pumped into it.

6. 1st evaporator, 2nd evaporator: used to separate the solvent from the oil. After this process,

the solvent can be removed 85%.

7. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be

discharged to condenser for recycling.

8. condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.

Refining Process:

crude oil → degumming&dephosphorization → deacidification → drying → decolorization → deodorization → defatting → dewaxing → finished oil.

Our developed oil refining equipments has unique skill, stable performance, high mechanical, and advanced technology index. Besides series products, we also can make reasonable combinationaccording to customers’ requirments to make the professional proposal . Our equipment has multi-functions, can be used not only to produce international first, second oil , but also high cooking oil and salad oil.

1. Deacidification:Adding a little P-acid to react with the collioid and a certained concentration lye to neutralize the free fatty acid, after reaction , producing many nigre, then we using the ce-ntrifugal machine to separate the nigre from the oil.Then washing the oil to separate the rest nigre and lye. After wash-ing , using the dehydration centrifugal to dehydrate the oil .

2.Decoloring section:Pre-mixing the a certain amount of clay with 20% degumming oil in the pre-mix tank , then using the oil pump pump the pre-mixing oil and the rest 80% oil in the vacuum decolorization tower to get rid of the pigment, then using plate-type filter to separate the oil and the waste clay.

3.Deodorization Section:In the condition of the high temperature and high vacuum, injecting a cert-ain amount of superheati-ng direct steam, the steam completely contact with the surface of the oil li-quid , taking the varities odors away .
