Abstract
In order to be able to unload the powdery product (5), for example whole-milk powder, from a silo (4) through an unloading aperture connected to an outlet pipe (8) and arranged in a filter-like plate (6), the product (5) is aerated through the plate (6) and, at the same time, the plate (6) is made to vibrate vertically by a vibrator (26). In this case, it is important that the aerating and the vibration regions are spatially not or hardly separated from one another, and that the joint action of the aeration and the vibrations extends up to the unloading aperture. Such a method makes it possible to cause adherent powdery products to flow continuously, it being possible for the outflowing quantity to be influenced by the quantity of air supplied. <IMAGE>
