Rapeseed Oil expeller process:
Cleaning and Weighing Section
Rapeseeds from daily bin or warehouse is treated by magnetic separator, weighing scale and screener to remove impurities.
Conditioning Section
The purpose of conditioning is to adjust moisture, temperature and tenacity of rapeseeds for better flaking.
Flaking Section
The purpose of flaking is to turn the broken rapeseeds 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.
Cooking Section
Horizontal drum cooker is designed to adjust temperature and moisture of rapeseeds flakes previous to mechanical pressing, improving oil yield greatly.
Pressing Section
Rapeseeds is a kind of high oil containing oil seed. Generally it is necessary to extract a portion of oil by mechanical pressing previous to subsequent process. The content of residual oil in pressing cakes is around 18 percent. Cakes is then treated by solvent extraction while crude oil is to be filtered.
