THE OVAL TUNNEL (COMBI) SYSTEM

• This is used for killing rates of up to 600 pigs per hour.
• The gas tunnel is in the form of an oval through which a slot conveyor carries pigs, the actual tunnel sloping downward at an angle of 30˚ to the anaesthetizing chamber.
• On exit the pigs are shackled, hoisted to an overhead rail and bled.
• The actual conveyor in the tunnel is divided into ten compartments, one pig being accommodated in each compartment.
• Pigs up to 113 kg can be handled in this equipment, which is not suitable for other species.
