<p>In stunning of slaughter animals by means of a box stunning apparatus with stunning atmosphere, boxes (1, l a, l b, l c, l d) are conveyed around after one another to various stop positions by means of a transport system (11, 12). Animals to be stunned are driven forwards in a driveway (2) and into an entrance area (3). The animals in the entrance area are separated from other animals after a group of animals has passed into the area. The group is driven into an empty box (1) that is brought to a halt in the first stop position at the entrance area. The box is then conveyed into the stunning atmosphere. After the animals have been in the atmosphere the box is conveyed out of the atmosphere and is brought to a stop at an emptying area (13) to empty the box of stunned animals. The present method comprises the steps of: measuring a time period comprising a separation time that elapses from a first state, at which the animals pass or are allowed to pass into the entrance area (3), and to a second state occurring during the period from the time when a group of animals has passed into the entrance area to the time when the group has been driven into the box or the filled box is ready for transport, calculation of a desired box transport time to a third state, at which the filled box has been lowered into the atmosphere and a certain event occurs, which calculation is performed on the basis of the time period measured, and controlling the transport system with a view to obtaining the desired box transport time to the third state. The method makes it possible to achieve a more optimum stunning process and operation of the apparatus compared with current practice, which employs fixed time intervals and box transport time. Operations are more stable, and CO2 consumption is reduced.</p> |
