Application of Vacuum System in Deacidification Processing of Fats and Oils
Release Time:
2025-05-21
The following focuses on the application of vacuum system in oil and grease deacidification processing, to provide you with reference. The unrefined crude oil contains some free fatty acids, and the process of removing free fatty acids from fats and oils is called deacidification. Deacidification methods include alkali refining, distillation, solvent extraction and esterification. The most widely used methods are alkali refining and distillation. Distillation deacidification method is also known as physical refining method, that is, the free fatty acids in crude oil is not neutralized with alkali reaction, but by vacuum distillation to achieve the purpose of deacidification of a refining method. Distillation deacidification method usually adopts steam injection vacuum pump to realize vacuum, this method needs to consume a large amount of water vapor, so the water consumption is high, and will form a large amount of waste condensate, resulting in the production site slippery and hot and humid working environment, there is a potential safety hazard.
