Rapeseed oil is also named canola oil. Rapeseed Oil is a totally natural product. We extract the oil using a mechanical Oil Press without the using of chemicals to ensure the natural goodness of the oil is preserved. As rapeseed oil has half the saturated FAT and 10 times the Omega 3 level of Olive Oil, many top cardiologists now recommend Rapeseed Oil as part of a low cholesterol diet. In addition it is suitable for high temperature cooking as it has a much higher smoke point than extra virgin olive oil.
Rapeseed oil processing machine starts with rapeseed, with oil content 40%, more or less. Same with other common oilseeds, there’re four main sections of rapeseed oil extraction plant, including prepressing/pressing/pretreatment section, solvent extraction section, refinery section and dewaxing/winterization section.
There are four big parts in solvent extraction workshop.They are solvent system, desolventizing system, condensing system and recycling system. We can get rapeseed wet meal and crude rapeseed oil.Rapeseed wet meal can be as animal feed, crude rapeseed oil contains solid impurity, chemical impurity and smelly odour etc. So crude rapeseed oil can go to next refinery workshop.

The purpose of rapeseed preparation plant is to extract a portion of oil by mechanical pressing while providing pressing cakes for extraction plant. Main processes include: Seed Cleaning & Weighing, Conditioning, Flaking, Cooking, Pressing, Oil Residue Separation.
Cleaning & 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. Vertical conditioner is used in this section. Flaking Section The purpose of flaking is to flake 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 rotary cooker is designed to adjust temperature and moisture of rapeseeds flakes prior to mechanical pressing, improving oil yield greatly.
Pressing Section Rapeseeds is a kind of high oil-containing oilseed. Generally it is necessary to extract a portion of oil by mechanical pressing prior to subsequent process. The content of residual oil in pressing cakes is around 18%. Cakes is then treated by solvent extraction while crude oil is to be filtered. Oil Residue Separation 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 horizontal screw centrifuge or leaf filter for further removing impurities.
Cooling Section Hydraulic turning cooler with complete set of wind network system is designed to cool down pre-pressing cakes to 55~60℃, then cakes is conveyed to extraction plant.

Rapeseed oil is widely available and public health advice encourages its use as a substitute for saturated fats as UK diet and nutrition surveys reveal we’re eating too much. Replacing saturated fats with unsaturated fats such as rapeseed oil has been shown to reduce blood cholesterol, which is beneficial for heart health.
