Ancient oil pressing method of rapeseed oil

Rapeseed oil is a common edible oil, and its production history can be traced back to ancient times. In ancient times, people used oil presses to extract rapeseed oil from rapeseed. Oil presses are usually made of stone or wood and driven by human power. These oil presses are usually large and can be used to process a large number of rapeseed. The working principle of the oil press is to put rapeseed into the funnel of the oil press and turn the oil press with the handle. In this way, rapeseed will be compressed and oil will be released. With the passage of time, the design of hydraulic press has been gradually improved to improve efficiency and productivity. Modern rapeseed oil production lines usually use machines to replace these traditional oil presses.

With the passage of time, the production mode of rapeseed oil has also changed. Modern rapeseed oil production lines usually use chemical methods to extract oil, while the traditional methods are gradually eliminated. However, there are still some places that still use the traditional oil pressing method to make rapeseed oil. These places are usually remote areas and people's lifestyles are more traditional. This traditional oil recovery method can not only preserve the ancient cultural heritage, but also provide employment opportunities and economic benefits for local residents.
