Forming a coated core by using a fluidized bed processor that discharges a spray containing atomized air and a coating solution where the coating solution contains an active. Then, wetting the core with the coating solution and drying the wetted cores to form coated cores. These steps can be repeated until an appropriate amount of active has been applied. The coated cores are visually perceived as smooth under a microscope with a total magnification of 40×.
