| 摘要 | A method and apparatus for stunning animals intended to be slaughtered wherein the animals are introduced into and displaced from above downwardly in a closed environment (1) containing a stunning gas mixed with air at an increasing concentration with a top to bottom vertical gradient from a preset initial value to a final higher value. The stunning gas concentration is detected in the upper area (2) of the environment (1) and in case the detected concentration is higher than the preset initial value, the external air is automatically supplied to the upper area at a pressure slightly higher than the atmospheric pressure until the preset initial value is restored. | ||

| 主权项 | 1. A method for stunning animals intended to be slaughtered wherein the animals are introduced into and displaced from above downwardly in a closed environment (1) containing a stunning gas mixed with air at an increasing concentration with a top to bottom vertical gradient from a preset initial low value to a final higher value, wherein the concentration of the stunning gas is detected in the upper area (2) of the environment (1), characterized in that in case the concentration value of the stunning gas detected in the upper area (2) of the environment (1) is higher than said preset initial value, external air is supplied to said upper area (2) at a pressure slightly higher than the atmospheric pressure until said preset initial value is restored. | ||
