The SFV type Vibratory Extractor is used for the extraction of flour from collection silos and difficult-to-flow products.

The machine consists of a truncated cone to which a convex bottom is attached, via suspension rods, directly coupled to a motor-vibrator, containing a convex circular shield which allows the uniform flow of the product. The width of the angle of inclination from the vertical of the cone is inversely proportional to the difficulty of sliding the product. The seal between cone and bottom is ensured by an elastic rubber band.
