Red and white viscera can automatically unhook and tip over the tray. As for the washing device, it allows both manual and automatic control of the washing tray, which further increases the level of automation. Besides, the white viscera can fall into the tray because the inspection operates under the carcass conveyor, which reduces labor intensity and increases productivity.
