How to improve the oil yield when pressing rapeseed oil has always been a concern for manufacturers. For rapeseed oil producers, the higher oil yield of rapeseed, the more rapeseed oil is obtained and the higher the profit income. The following is a list of methods for improving the oil yield from rapeseed based on the experience of Henan Glory Company engineers. You can have a try.

1.Selecting rapeseed varieties with high oil content
Selecting rapeseed varieties with high oil content is a guarantee of high oil yield. After years of scientific research and practical proof, “Sunshine 2009”, “Sunshine 198”, “Zhong Shuang No. 12” and other varieties have a high oil content, generally achieve at 45%. Therefore, these varieties can be given priority when selecting rapeseed.
2.Pre-treatment operations for rapeseed
Pre-treatment of rapeseed prior to pressing rapeseed can improve the oil yield of rapeseed. Pre-treatment of rapeseed includes cleaning, flaking and cooking etc. It can easily removes impurities and regulates the temperature and moisture of the seeds, resulting in a smoother processing process and higher oil yield.

3.Choosing high oil yield rate processing technology
There are two different processing technologies to produce rapeseed oil: pressing technology and pre-press & solvent extraction technology. The residual oil rate of pressing technology is about 6%-7%, and the residual oil rate of pre-press & solvent extraction technology is less than 1%. If you have enough budget, I suggest you choose to use pre-press & solvent extraction technology, which can meet your needs for both production and quality.

4.Ensuring the correct operation of the workers
Ensuring the correct operation of the workers can also improve the oil yield of rapeseed to a certain extent. Regularly cleaning the oil gaps in the frying strips and rings, reasonably controlling the feed rate, adjusting the feed volume and increasing the temperature in the frying chamber can all form good pressing conditions, ensuring normal oil production while keeping the oil yield of rapeseed oil at a high level.
These are the methods for improving the oil yield from rapeseed given by the engineers of Henan Glory Company.
