  • Patent number: 4312596
    Abstract: A beating blade member for beating or whipping cooking material such as egg into froth. The blade member has blades each of which has a vertically stretched and radially extending beating surface in which formed are a multiplicity of meshes. Thanks to the provision of these meshes, it is possible to obtain fine contact of the material with the blade to promote the stirring and beating. Also, these meshes effectively catch the ambient air to permit a better mixing of the material with the air. At the same time, the material is guided to flow radially inwardly, as well as in the vertical direction, so as to ensure the interference of the material with the meshes of the blades. Consequently, the material is beaten and whipped into froth in quite a short period of time.
