The invention relates to a gas distributor for, and a method of, controlling the velocity profile of a drying gas in a convective dryer, particularly the radial velocity profile, by creating an advantageous velocity profile prior to introducing the drying gas into the convective dryer chamber. The velocity profile may have different requirements depending on the convective process, chamber dimensions and atomizing means, but common gas distributor targets may be defined, such as a uniform velocity distribution and axial alignment. The invention further concerns a convective dryer comprising the gas distributor of the present invention, the use of said method to produce a powdery substance in a convective dryer according to the present invention.
A gas distributor for directing a drying gas jet into a drying chamber of a convective dryer, said convective dryer configured for producing a powdery substance from an atomized liquid, said gas distributor configured to generate a drying gas jet protruding from an exit surface of said gas distributor into said drying chamber, said drying gas jet having a center axis aligned with an axis of said gas distributor essentially perpendicular to said gas distributor exit surface;
A gas distributor for directing a drying gas jet into a drying chamber of a convective dryer, said convective dryer configured for producing a powdery substance from an atomized liquid, said gas distributor configured to generate a drying gas jet protruding from an exit surface of said gas distributor into said drying chamber, said drying gas jet having a center axis aligned with an axis of said gas distributor essentially perpendicular to said gas distributor exit surface;
A convective dryer configured for producing a powdery substance from an atomized liquid, said convective dryer comprising at least one gas distributor configured to generate a drying gas jet, said jet protruding from an exit surface of said gas distributor into a drying chamber of said convective dryer, said drying gas jet having a center axis aligned with an axis of said gas distributor;
A method for controlling the gas velocity field of a drying gas jet protruding from a gas distributor into a drying chamber of a convective dryer, said gas velocity field comprising an axial gas velocity component, a tangential gas velocity component and a radial gas velocity component, said method comprising minimizing said radial gas velocity component such that said radial gas velocity of said gas jet is low or zero.
