PURPOSE: A carrier coating apparatus is provided to reduce the consumption of a catalyst by collecting the extra catalyst discharged from a carrier container and reuse the catalyst. CONSTITUTION: A carrier coating apparatus comprises the following: a carrier container(100) in the cylindrical shape with an opened upper side to store a carrier; a rotating unit(300) rotating the carrier container while including multiple holes on the lower and the side surface, and a rotary motor(310) connected to the lower center of the container; a catalyst spray unit spraying the catalyst to the surface of the carrier; and a catalyst collecting unit collecting the catalyst discharged from the carrier container by the centrifugal force from the rotating of the carrier container.
