METHOD AND APPARATUS FOR STUNNING POULTRY

摘要

A method for stunning poultry in a slaughterhouse by means of supplying a stunning gas into a closed chamber wherein the poultry is advanced through a plurality of successive ambients between an inlet, wherein the stunning gas concentration is at a minimum, and an outlet, at which the stunning gas concentration is at a maximum. The stunning gas concentration increases progressively from each ambient to the successive ambient, initially with a minimum increase rate and thereafter with a higher increase rate up to the maximum concentration.

主权项

1. A method for stunning poultry in a slaughterhouse, comprising: supplying a stunning gas into a closed chamber through which poultry is advanced between an inlet and an outlet, wherein a concentration of said stunning gas is at a minimum at the inlet and at a maximum before the outlet of said chamber;
the poultry advanced through a plurality of successive ambients of said chamber, said chamber having a plurality of initial ambients and a successive ambient; increasing a concentration of the stunning gas progressively from a first initial ambient of said initial ambients to a second initial ambient of said initial ambients; increasing the concentration from said second ambient to said successive ambient; and wherein a first rate of increase of said concentration between said first initial ambient and said second initial ambient is less than a second rate of increase of said concentration between said second ambient and said successive ambient.
