Abrégé

The invention relates to a method for drying moist products, in particular moist granules for producing pharmaceutical products through which a fluid medium flows in a reactor chamber of a bulk goods dryer and which are heated and placed on a fluid medium-permeable inflow base. The inflow base is vibrated via a vibrational drive in order to convey the products from a product inlet to a product outlet, and the fluid medium is supplied to separate chambers arranged upstream of an outlet and to the outlet after flowing through the inflow base and the product. One of the at least two separate chambers is preselectably closed off from the outlet by actuating a closing element such that after the closing element has been actuated, the supply of the fluid medium to the outlet is carried out via a chamber which is not closed by another closing element, and a fluid medium filter element paired with the closed chamber is cleaned via a pulse emitter after the closing element of said chamber is actuated in the closing direction while the fluid medium is continuously supplied to a non-closed chamber.
