Canola oil, known for its natural composition, is extracted using mechanical oil presses to maintain its quality. With an oil content of about 40%, the Henan Huatai canola oil production line encompasses several key stages: pre-pressing, pressing, pretreatment, solvent extraction, refining, and dewaxing/winterizing.
Huatai Oil Machinery offers comprehensive customization for canola oil production lines ranging from 20 to 5000 TPD.
The initial step involves cleaning the canola seeds to eliminate mechanical impurities. This is achieved through a selection process, gravity destoning, and magnetic separation, effectively removing clay, stones, metals, and other contaminants.
Softening adjusts the canola seeds' temperature and moisture using steam. This is typically done with a rotary or flat-bottom roaster to reach the desired levels of heat and humidity.
The process of flaking transforms granular oil seeds into thin layers, aiding in the pressing and extraction processes and ensuring a smoother oil flow during these stages.
Cooking involves moistening, heating, steaming, and cooking the flakes to alter their internal structure, facilitating easier oil extraction from the seeds.
Roasted canola seeds are fed into the canola oil press machine, where a rotating worm and main shaft push them forward. As the space inside the pressing chamber gets smaller, the pressure inside builds up. The machine has a built-in heater that warms the barrel automatically, and the heat from friction also contributes. This process breaks down the cells in the seeds, releasing the oil.
The oil then moves to a filtering barrel, where a vacuum pump draws it into the barrel, leaving behind solid residues on a filter cloth. This results in the extraction of pure canola oil. From this process, we obtain both crude canola oil and the solid byproduct, pressed oil cake meal, which can be used for other purposes.
The cold pressing method for extracting canola oil is straightforward and traditional, avoiding heating or chemical treatments. This method retains the most nutrients in the canola oil. Known for producing natural and high-quality oil, it typically requires no additives and has a long shelf life. While the market value of cold-pressed oil is high, the oil produced is less than that of the hot-pressing method.
GET A QUOTECanola oil solvent extraction is an efficient method to extract the maximum amount of oil from canola seeds, especially since the pressed canola cake meal retains a significant amount of oil.
This extraction technique involves four main stages: the solvent system, which dissolves the oil; the desolvent system, which separates the oil from the solvent; the condensing system, which condenses the solvent vapors; and the recovery system, which recovers the solvent for reuse.
The outcome of this process is wet canola oil powder and unrefined canola oil. The wet canola meal, rich in nutrients, is an excellent animal feed. The unrefined canola oil, however, contains various impurities and odors that need to be removed through a refining process to ensure the oil's purity and quality.
The canola oil refinery plant plays a crucial role in purifying crude canola oil by removing harmful impurities. The refined oil is free from free fatty acids (FFA), colorless, odorless, and conducive to human health and storage.
