由于流化床设备有极高的蒸发效率，颗粒悬浮在气流中，进行包衣，使得这一技术能广泛地适用于粒芯包衣。
This technique is widely applied to granule core coating because due to high evaporation rate of fluidized bed, the granule could be coated when suspended in the air stream.
包衣：颗粒、丸剂保护层、着色、缓释、薄膜、肠溶包衣等。
Coating: granule, pill protection layer, pigmentation, controlled release, film, or bowels solved coating.
结果对颗粒进行薄膜包衣可提高颗粒剂的稳定性，降低不良气味。
Results Film coating for granule could improve the stability of granule and lower the bad odor.
