The invention relates to a process for producing nanostructured or makrostructured materials and devices for their production. The principle of the invention consists in that a solution, emulsion or liquid suspension of one substance or a mixture of substances or microorganisms optionally saturated with a gas, liquefied gas or supercritical liquid, is fed into an inner space of a disc through a hollow shaft, and by means of the combination of a centrifugal force and fluid pressure occurs the outlet of the liquid through an expansion gap, to form microscopic droplets. The microscopic droplets are subsequently secondarily disintegrated by expansion of the gas comprised therein to smaller droplets, to form an aerosol. The aerosol is subsequently dried by a drying gas stream to form solids. In special cases, when drying some polymers under certain conditions, microfibers or nanofibers can be created instead of corpuscular forms. The subject matter of a device for producing nanostructured and microstructured materials consists in that it comprises a chamber in which a hollow shaft is assembled, on which at least one disc provided with an expansion gap is mounted, wherein the hollow shaft has openings which connect the inner space of the hollow shaft with the expansion gap. The chamber may additionally be provided with an independent feed nozzle. |
