VEVOR - An electric sifter sieving machine is a device that is used to separate and sift materials, such as flour, sugar, or other fine powders, using an electric motor to rotate a series of sieves. The machine works by passing the material through a series of screens or sieves that have different-sized openings. As the material moves through the screens, the smaller particles fall through the openings, while the larger particles are retained on the screen.
