DEVICE FOR DRYING POURABLE PRODUCTS AND METHOD FOR USING SAME

摘要

The invention relates to a device for drying pourable products, comprising a rotor chamber (1) in which a rotor (2) having a vertical rotor axis (3) is positioned. The rotor (2) has a horizontal central surface and at least along its radially outer third has a conical envelope (22) which is inclined in relation to the axis of rotation (3) at an angle of between 20~ and 70~ in such a way that the face of the conical envelope (22) having the greater diameter is situated at the top. The envelope (22) has at least partly flat gas passages in the shape of holes or screens. The method provided for in the invention uses the above device for drying pourable products. To this end dry gas is supplied to the surface of the products to be dried during the radial, peripheral circulation of same, without said products being whirled up and subjected to inadmissible pressure, shock and/or friction.
