A method for manufacturing an animal excrement disposal material comprising: a step of obtaining a granule by granulating a raw material, and a step of obtaining an uneven colored layer by applying unevenly a coloring agent to the granule, wherein: the step of applying the coloring agent to the granule has a step of floating the granule and a step of ejecting the coloring agent onto the floated granule, wherein, in the step of applying the coloring agent to the granule, the coloring agent is applied to the granule by a coloring agent applying machine, the coloring agent applying machine includes a rotating drum rotated by a rotating mechanism, a coloring agent applying chamber formed inside the rotating drum and having an inner wall surface to receive the granule, a nozzle applying a liquid coloring agent to the granule, and a pipe connected to the nozzle for transporting the liquid coloring agent, wherein, in the step of floating the granule, the granule is separated from an inner wall surface which forms the coloring agent applying chamber, the granule subjected to the steps of applying the coloring agent has a first region, a second region and a third region, the first region impregnated with the coloring agent, the second region in which the coloring agent is layered on a surface of the granule, and the third region in which the coloring agent is not applied to the surface of the granule. a step of obtaining a granule by granulating a raw material, and a step of obtaining an uneven colored layer by applying unevenly a coloring agent to the granule, wherein: the step of applying the coloring agent to the granule has a step of floating the granule and a step of ejecting the coloring agent onto the floated granule, wherein, in the step of applying the coloring agent to the granule, the coloring agent is applied to the granule by a coloring agent applying machine, the coloring agent applying machine includes a rotating drum rotated by a rotating mechanism, a coloring agent applying chamber formed inside the rotating drum and having an inner wall surface to receive the granule, a nozzle applying a liquid coloring agent to the granule, and a pipe connected to the nozzle for transporting the liquid coloring agent, wherein, in the step of floating the granule, the granule is separated from an inner wall surface which forms the coloring agent applying chamber, the granule subjected to the steps of applying the coloring agent has a first region, a second region and a third region, the first region impregnated with the coloring agent, the second region in which the coloring agent is layered on a surface of the granule, and the third region in which the coloring agent is not applied to the surface of the granule. the step of applying the coloring agent to the granule has a step of floating the granule and a step of ejecting the coloring agent onto the floated granule, wherein, in the step of applying the coloring agent to the granule, the coloring agent is applied to the granule by a coloring agent applying machine, the coloring agent applying machine includes a rotating drum rotated by a rotating mechanism, a coloring agent applying chamber formed inside the rotating drum and having an inner wall surface to receive the granule, a nozzle applying a liquid coloring agent to the granule, and a pipe connected to the nozzle for transporting the liquid coloring agent, wherein, in the step of floating the granule, the granule is separated from an inner wall surface which forms the coloring agent applying chamber, the granule subjected to the steps of applying the coloring agent has a first region, a second region and a third region, the first region impregnated with the coloring agent, the second region in which the coloring agent is layered on a surface of the granule, and the third region in which the coloring agent is not applied to the surface of the granule.
