Canola Seed Oil Pressing Plant
Canola Seed Oil Pressing Plant
The purpose of canola seed 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.
1. Cleaning & Weighing Section
Rapeseeds from daily bin or warehouse is treated by magnetic separator, weighing scale and screener to remove impurities.
2. 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.
3. 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 the roll pressure adjustment device.
4. Cooking Section
Horizontal Drum Rotary Cooker is designed to adjust temperature and moisture of rapeseeds flakes prior to mechanical pressing, improving oil yield greatly.
5. 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 the 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.
6. Oil Residue Separation Section
Due to the 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. The 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.
7. Cooling Section
Hydraulic turning cooler with a complete set of wind network system is designed to cool down pre-pressing cakes to 55~60℃, then cakes is conveyed to the extraction plant.
Canola Seed Oil Refinery Plant
Canola Oil Refinery process include: Degumming, Neutralizing, Bleaching, Deodorizing and sometimes dewaxing (Mainly removing free fatty acid and other minor constituents). The process is suitable for refining soybean oil, rapeseed oil, sunflower oil, palm oil and etc.
The purpose of degumming is to remove impurities such as phospholipids, gums, proteins and etc. There are several methods as follows: water degumming, acid degumming, special degumming and etc.
The purpose of neutralizing is to remove free fatty acid in edible oil by using caustic soda while removing impurities such as phospholipid, pigments, metal ions and peroxide under the adsorption of soap stock.
Bleaching is the process which removes coloured matters by mixing bleaching earth with edible oil under controlled conditions of temperature. After proper mixing with bleaching earth for a specific residence time, the mixture is finally pumped into leaf filters with stainless steel mesh elements followed by polishing filtration.
Deodorizing is the final stage in edible oil refining in order to remove odoriferous material, free fatty acids and other undesired minor components by steam distillation under condition of high temperature and vacuum to produce a bland oil with a good shelf life.
Through automatic control system, combined with crystallization curve (time-amount of crystallinity) of different oil, crystals in oil grow and finally can be separated by filtration to obtain dewaxed oil.
