Abstract:
Apparatus is described for producing microspherical particles. Also described is a method for operating said apparatus. A droplet generator dispenses uniform spherical droplets into a gelling column which is sealed at both ends to prevent entry of air thereinto. A gelling liquid and a gelling gas are provided in the column, and a further gas, which is of a density lower than that of the gelling gas, is introduced to the region above the gelling gas. At the interface between the gelling gas and the further gas, the gases are withdrawn from the gelling column.
