Rice bran oil is a kind of vegetable oil made from by-products, and its fatty acid is suitable for the human body to absorb, which is recognized as a nutritious and healthy health oil in the world. However, because of the high acid value, deacidification is the most important step in the molecular distillation of rice bran oil .
The process includes feeding, vacuum distillation purification, molecular distillation, separation and purification, and collection. Molecular distillation of rice bran oil technology is an emerging technology for oil and grease deacidification, which has the advantages of low energy consumption, low damage to oil and grease, and cleanliness.
