BRIEF INTRODUCTION OF PRETREATMENT:

1.Screening: Removing the chaff and broken rice in the rice bran, in case of they will influence

the oil yield 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 enLDme 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:

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. DTDC: 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.
