Abstract: An automatic apparatus includes an input platform, a creature shaking mechanism, a flushing unit and an output platform. The input platform has a transporting unit. A creature container containing at least one creature is placed on the input platform. The creature shaking mechanism is connected to the input platform. When the creature container is transported to a positioning region of the creature shaking mechanism, the creature container is subject to a shaking operation in response to a power source, thereby turning over the creature and exposing different surfaces of the at least one creature. The flushing unit generates a spout of water to flush the different surfaces of the at least one creature so as to sufficiently shed superficial adherent substances off the at least one creature. The output platform is connected to the creature shaking mechanism for receiving the creature container that is departed from the positioning region.
