The degumming, deacidification and other processes in canola oil refining equipment have the following main purposes:

1. degumming:

remove the colloidal impurities in canola oil, such as phospholipids, proteins and so on. These impurities will affect the stability and quality of the oil, through degumming can improve the transparency and storage stability of the oil.

2. Deacidification:

Reduce the acidity in canola oil, mainly to remove free fatty acids. Higher acidity oil is easy to deteriorate, deacidification can prolong the shelf life of the oil and improve the flavor of the oil.

3. decolorization:

remove the pigment and other impurities in the oil, make the color of the oil lighter and improve the appearance quality of the oil.

4. deodorization:

reduce or remove the bad odor components in canola oil, make the odor of oil more pure and pleasant.

5. Remove harmful substances:

some refining processes can also remove residual pesticides, heavy metals and other harmful substances to improve the safety of the oil.

Canola oil refining equipment

Through these refining processes, the quality and stability of canola oil can be improved, making it more suitable for consumption and storage. Different refining equipment and processes may vary, but the overall goal is the same.

The wastewater generated may contain oils and fats, acids, alkalis, organics and other impurities. In order to minimize the impact on the environment, wastewater treatment is usually required. Methods of wastewater treatment may include physical treatment, chemical treatment, and biological treatment.

Physical treatment may include steps such as filtration, sedimentation, and oil-water separation to remove suspended solids and oils and fats from the wastewater. Chemical treatment may use methods such as neutralization and flocculation to precipitate or coagulate pollutants in the wastewater. Biological treatment, on the other hand, can utilize microorganisms to decompose organic matter into harmless substances.

In addition, rational process design and operation management can also reduce the amount of wastewater generated. For example, the use of efficient oil and fat refining equipment, optimization of process flow, water conservation and other measures can reduce the generation of wastewater. When treating wastewater, it is also necessary to comply with local environmental regulations to ensure that wastewater is discharged according to standards.
