This pre-scalder is specially developed to improve the processing of ducks and other waterfowl. The majority of dirt and other small particles will be removed from the feather pack in this stage. Thereby creating a much cleaner operation of the main scalder. Another advantage is the partly opening of the feather pack, this significantly improves the scalding performance because the bird’s skin can be reached easily. The integrated water treatment system circulates and heats the water. Larger particles will be filtered out of the water by the build-in filter screen and a pump.
