Rapeseed oil yield

1. Oil yield

Under normal circumstances, the oil yield of rapeseed is not very high, about 30% to 40%, which means that every 100 kilograms of rapeseed can produce about 30-40 kilograms of oil. There are many varieties of rapeseed, and different varieties will also affect its oil yield. In addition, the climate in some areas is very good, so the oil yield will be higher.

2. Methods to improve oil yield

1. Remove impurities: Generally, there are some mud and sand in rapeseed. It is best to remove these mud and sand impurities before oil extraction, otherwise it will absorb oil during the oil extraction process and affect the oil yield to a certain extent.

2. Pressing on hot materials: Some people may not know that oil molecules are most active when the temperature is high, so it is necessary to press while the material is hot, which will increase the oil output.

3. Adding bran: When pressing oil, you can add some bran, and sift out the ash when using it. After adding, it can slow down the sliding speed of rapeseed, so more oil can be extracted.
