The most commonly used extraction process to produce high oil yield from canola seeds involves both mechanical pressing and solvent extraction as shown in Fig. 1. Daun [ 68] has detailed the conventional extraction of canola oil. A series of steps occur prior to and in preparation for expeller pressing.
What is the commercial processing of canola and rapeseed?
Unger EH (1990) Commercial processing of canola and rapeseed: crushing and oil extraction. In Canola and Rapeseed, Springer, p 235–249 Uquiche E, Romero V, Ortiz J, Del Valle J (2012) Extraction of oil and minor lipids from cold-press rapeseed cake with supercritical CO2.
How to process canola seed?
For processing Canola seed, the basic equipment we need are Seed Cleaner, Seed Cooker/Kettle, Oil Press, Filter Press, Steam Boiler, Screw Conveyors & Bucket Elevators. The following are steps involved in Canola Oil Extraction Plant: Step 1. Seed Cleaning Canola Seeds are separated and cleaned to remove impurities such as dust, metal, plant stalks.
How is canola oil pressed?
In Mechanical Press, Canola oilseeds are pressed in a series of Screw Presses / Expellers. This process uses no chemical and leaves about 5-7% oil in the residual Cake/Meal. This pressed cake can be subjected to Solvent Extraction for further Oil Extraction. Step 4. Solvent Extraction
