Method and device for continuously producing a coherent layer of a liquid/melt of even thickness by means of centrifugal action along the entire periphery of a rotating disk (), liquid/melt being supplied to the disk around its entire axis of rotation from means () and leaving the disk as individual droplets. The means () distributing the liquid/melt onto the disk () has according to the invention essentially the same speed and direction of rotation as the disk, and the liquid/melt undergoes under the influence of centrifugal action circumferentially a spreading and change in velocity across the disk () in contact with the same.

The invention refers to a method of controlling the porosity of porous spherical particles produced from a polysaccharide dissolved in a solvent, in which it can be gelled. The polysaccharide solution is finely divided by mechanical means into spherical droplets which are allowed to pass through a humid atmosphere and transferred to a capturing medium while controlling the temperature and humidity of humid atmosphere.
