THE COMPACT CARBON-DI-OXIDE IMMOBILISER

• This is a horizontally-revolving apparatus divided into four to eight compartments operating in such a way that, when one section is uppermost for loading, the others are rotating to submerge in the gas chamber.
• The unit usually has a capacity of up to 300 pigs per hour.
• In commonly used design the pigs are exposed to 10% CO₂ at the first position, 30% for 10s at the second, 60% for 10s at the third and over 90% for 20s at the fourth and fifth, after which the pigs are discharged from the unit.
