The hog bung (rectum) inverter is made from an AISI 304 stainless steel framework, on which a cylindrical tank is mounted on. Inside the tank, a suction pump creates a drop in pressure. When the bung is inserted on the reversal duct, it gets sucked inside the tank, and, at the same time, it gets inverted. The tank reclines to allow for easy unloading and is equipped with a manual or pneumatic door. The machine is equipped with an electric panel with low tension 24 V push-buttons.
