Abstract: A scalding tunnel for slaughter animals such as pigs or goats, including steam-discharging nozzles which are mounted inside the scalding tunnel and along the path of conveyance of the slaughter animals. The scalding tunnel has a structurally simple design and operates in an energy efficient manner. To be able to set homogeneous or largely homogeneous environmental conditions inside the scalding tunnel, the invention provides that the nozzles are multicomponent-discharging nozzles having at least one connection for steam and one connection for water, whereby the nozzles discharge a mixture including steam and water that is sprayed therein.
