Why is oilseed pretreatment the core of oil extraction process?

Today, let's discuss a crucial, often overlooked step in oil extraction: oil pretreatment . As an essential process in any edible oil production line , it directly impacts oil yield and oil quality stability , ultimately driving a factory's profitability.

Analysis of industry pain points :

• If peanut oil production skips crushing, flaking , and steaming and frying temperature control , not only will the fragrant peanut oil not be squeezed out, but it will also cause increased wear and tear on the oil press equipment .
• In soybean oil processing, the lack of cleaning, impurity removal , and softening and puffing processes will reduce the oil yield by 3%-5%;
• Rapeseed oil has not undergone "rolling thickness adjustment" and "steaming and frying time optimization ," resulting in a low oil yield and inability to fully release flavor substances.

The three major values ​​of scientific preprocessing :

1. Increased production and efficiency : Oil pretreatment equipment (such as cleaning screens and flaking mills) can increase oil yield by 15%-20%.
2. Quality assurance : Reduces oil acidity and solvent residues, meeting national standards for edible oils ;
3. Equipment protection : Extend the service life of the screw oil press and reduce maintenance costs.
