Next, by lifting up the scum remover, by weight of the broth, the lid 3 of the scooping part opens, and only the broth from which scum is removed by a filter, returns to a pot. In addition, the filter is fixed by only a protrusion, so that, the filter does not float even if the broth enters the scooping part, and the filter can be detached for washing and replaced.SELECTED DRAWING: Figure 1
