Rice bran oil machinery

Description of Rice bran oil machinery :
1. Cleaning & Weighing Section
Rice Bran from daily bin is treated by magnetic separator, weighing scale and screener with dedusting aspiration network to remove impurities.
2. Cracking Section
The purpose of cracking is to crack Rice Bran into small particles previous to softening and flaking, in order to improve the quality and capacity of the flaker.
3. Softening and Puffing Section
Horizontal drum softener is designed to adjust temperature and moisture of Rice Bran previous to flaking, improving oil yield greatly.
4. Flaking Section
The purpose of flaking is to turn the softened rice bran into thin flakes (from 0.3 to 0.35mm) for the subsequent oil extraction through mechanical pressing. In addition, flakes thickness can be adjusted through roll pressure adjustment device.
5. Pressing Section
Rice Bran is a kind of high oil-containing oilseed. Generally it is necessary to extract a portion of oil by mechanical pressing previous to subsequent process. Expeller with auxiliary cooker ensures material reach proper temperature and moisture. Pressing cakes containing residual oil from 14% to 18% is then treated by solvent extraction while crude oil is to be filtered.
6. Oil Residue Extraction Section
Due to high content of residue in crude oil, it is necessary to separate oil residue by oil drag conveyor firstly, crude oil then enters to settling tank for further separation. Collected residue is returned to pressing section while crude oil from settling tank is pumped to frame filter or leaf filter for further removing impurities.
7. Cooking Section,Filling and Packing
Cooling drag conveyor is designed to cool down pre-pressing cakes with high efficiency, then cakes is conveyed to extraction plant.
