Deodorization process


Deodorization process, generally not refined deodorized castor oil, if the product quality does not meet the quality standards may consider sweetening. An amount of 0.02% by weight of oil, the concentration of 5%, can be added at the beginning of deodorization. Due to the nature when deodorized castor oil castor acid requirements deodorization temperature should not be too high, and a high degree of vacuum requirements. Deodorization time 4h ~ 6h. After cooling to the deodorizer 70 ℃ ~ 80 ℃ deodorized oil is discharged.

If adding a small amount of citric acid in the deodorization process, can improve the oxidative stability of oils and fats. General deodorization temperature controlled at 140 ℃ ~ 160 ℃, absolute pressure 0.67Kpa less.
