The unique Bursten sifter brush is the heart of the Breader Blender Sifter. The brush rotates as breading mixture hits it, acting as an auger that ejects dough balls into a waste pan, while sifting and mixing the breading into the lug below for re-use. Bursten offers sifter brush options based on batter type, breading process and machine size. For best operation, the sifter brush should be replaced annually.
