The invention relates to a scalding tunnel (2) for slaughter animals (20) such as pigs or goats, comprising steam-discharging nozzles (30), which are mounted inside the scalding tunnel and along the path of conveyance of the slaughter animals. In order to be able to operate the scalding tunnel having a structurally simple design in an energy efficient manner and to be able to set homogeneous or largely homogeneous environmental conditions inside the scalding tunnel, the invention provides that the nozzles (30) are multicomponent-discharging nozzles having at least one connection for steam and one connection for water, whereby the nozzles discharge a mixture consisting of steam and of water that is sprayed therein.
