Under normal circumstances, the oil yield of rapeseed is not very high, about 30% - 40%. That is to say, every 100 Jin of rapeseed can yield about 30-40 Jin of oil. There are many varieties of rapeseed, and different varieties will also affect its oil yield. In addition, some areas of the climate is very good, the oil rate will be higher
1. Remove impurities: generally, there are some sediment in rapeseed. It's better to remove these sediment impurities before pressing oil. Otherwise, it will absorb oil in the process of pressing oil and affect oil yield to a certain extent.
2. Hot material pressing: some people may not know that the oil molecules are the most active when the temperature is high, so it should be carried out when it is hot, so it will increase the oil output.
3. Blending with bran: when pressing oil, you can add some bran in it. When using, you need to remove the ash contained. After blending, it can slow down the sliding speed of rapeseed, so it can squeeze more oil.
