The animal oil refining process is complex and typically involves several steps to convert raw animal fats into refined oils suitable for various applications such as cooking, biodiesel production, or industrial lubricants.

1. Harvesting: Raw materials are obtained from slaughterhouses, rendering plants, or directly from animals through processing techniques like skinning and fat removal.

   

2. Dewatering: The raw material (fat) contains water and other impurities that need to be removed before further processing.

3. Clarification: This stage removes suspended particles and impurities using centrifuges, filtration, or settling tanks.

4. Degumming: The clarified product may contain gums and waxes which need to be dissolved in organic solvents like hexane or ethanol to separate them from the oil.

5. Saponification: In this step, alkaline substances react with the fatty acids in the oil to form soap and glycerin. Glycerol is then separated and used in food industries or pharmaceuticals.

   

6. Decolorization/Removal of Residual Pigments: After saponification, pigmented compounds remain in the oil. These can be removed through distillation, solvent extraction, or chemical treatments.

7. Fractionation: This separates different types of fats based on their boiling points and specific properties. The lighter fractions can be used as base oils while the heavier ones are processed further.

8. Final Distillation: Depending on the desired final product, additional distillations might occur to achieve the correct viscosity and pour point.

9. Quality Control: Throughout the process, quality control measures ensure the purity and safety of the end products.

   

10. Packaging and Distribution: The refined oils are packaged according to industry standards and distributed globally.

This process requires specialized equipment such as degumming towers, fractionators, distillation columns, and purification systems. Equipment manufacturers specialize in providing these technologies and also offer services related to installation, maintenance, and operation support. Companies like Alfa Laval, Sartorius Stedim Biotech, and others are known for manufacturing advanced oil refining machinery.
