Hybridization system, Spraying chamber coating system and aerothermal fluidization spraying (ATFS) system, were tested to find an economic and practical method for vitamin coating. Ae coating by hybridization was done by commercial hybridizer. But both spraying chamber and aerothermal fluidization spraying system were developed by authors for this test. Two vitamins, Vit. E and Vit. C, were employed for coating with four different coating materials, such as eudragit, corn zein, ethylcellulose and gelatin. Coating by hybridization was unsuccessful due to high intake velocity, temperature increase, and bridge formation between vitamin particles. Spraying chamber system was marginally successful to coat vitamins. But the quality of coated vitamin was poor possibly because of the failure of uniform mixing between vitamin and coating materials inside the chamber. Vitamin coating was successfully achieved by ATFS system. The system enables to give not only uniform mixing between coating material and vitamin, but also drying of coated vitamin and uniform diffusion of vitamin particles by thermal aeration. This result was also confirmed through surface micrograph by scanning electron microscope. Therfore, the ATFS system can be considered as a practical system for coating sensitive materials such as vitamins as well as other feed additives.
