Dingsheng Machine Introduces Customized Rapeseed Oil Production Line Solutions
Date:Sep 23rd, 2024
Dingsheng Machine is proud to offer comprehensive solutions for rapeseed oil production lines, designed to meet the growing demand for this highly nutritious and natural oil. With an oil content of approximately 40%, rapeseed oil has become a staple in many markets. Our rapeseed oil production lines are tailored to the specific needs of our clients and can range from 30 to 5000 TPD, offering turnkey projects for efficient and high-quality oil extraction.
Key Processes in Rapeseed Oil Production:
1. Rapeseed Pre-Treatment Process
- Step 1: Raw Material Screening
The screening process is essential to remove impurities from rapeseeds. Our pre-treatment equipment uses gravity destoners, vibrating screens, and magnetic separators to eliminate impurities such as clay, stones, and metals.
- Step 2: Crushing
After de-hulling, the rapeseeds are crushed into small pieces to increase the surface area, which facilitates better oil extraction.
- Step 3: Flaking
The crushed rapeseeds are then rolled into thin flakes, further increasing the contact area between the oil and solvent, improving extraction efficiency.
- Step 4: Cooking
The flakes undergo cooking to adjust the temperature and moisture, making the oil easier to extract during the pressing process.
2. High-Quality and Reliable Solutions for Oil Pressing
- Pressing Process
The cooked rapeseed flakes are fed into the oil press machine, where a rotating screw pushes the material forward, gradually increasing the pressure inside the chamber. This process releases oil from the rapeseeds, which is then filtered through a vacuum pump system to obtain pure crude rapeseed oil. The result is both rapeseed oil and rapeseed meal, which can be sold as feed.
- Cold Pressing Process
Cold pressing is a simpler and more traditional method that skips the heating and chemical extraction stages, preserving the nutritional content of rapeseed oil. This method produces natural oil with no additives and high nutritional value, though the yield is typically lower than hot pressing. The oil has a longer shelf life and commands a higher market value.
3. Rapeseed Oil Extraction Process
- Extraction Process
Even after pressing, rapeseed cake still contains a high amount of oil. The extraction process, involving solvent systems, desolventizing systems, condensation, and recovery systems, maximizes the oil recovery. The final output is crude rapeseed oil and wet meal, which can be sold as animal feed.
4. Refining Process
- Rapeseed Oil Refining
Refining is a critical step in rapeseed oil production, removing harmful impurities from the crude oil. After refining, the rapeseed oil becomes clear, healthy, and suitable for storage. The refined oil has a low acid value and is ideal for human consumption.
