英文回答：
Canola Oil Extraction Process.
Step 1: Harvesting.
Canola is typically harvested in late summer or early fall when the seeds are mature and have turned brown. The plants are cut down and transported to the processing facility.
Step 2: Cleaning.
The canola seeds are cleaned to remove any dirt, chaff, and other impurities. This is done by passing the seeds through a series of screens and fans.
Step 3: Drying.
The canola seeds are then dried to reduce their moisture content. This is done to prevent the seeds from spoiling and to make them easier to crush.
Step 4: Crushing.
The canola seeds are crushed to break them down and release the oil. This is done using a large roller mill
that presses the seeds flat.
Step 5: Extraction.
The crushed canola seeds are then extracted to separate the oil from the other components. This is done using a solvent, which is a liquid that dissolves the oil but not the other components.
Step 6: Refining.
The extracted oil is then refined to remove any impurities and to improve its flavor and color. This is done by heating the oil and then filtering it through a
series of filters.
Step 7: Bottling.
The refined oil is then bottled and packaged for sale.
