気-液-液系を利用した固体球殻の連続生成

A new sequential production equipment of solid shells was designed. This method using liquid-liquid-gas systems is very simple comparing the previous method using chemical reactions or annular nozzles. For the first step to investigate the performance of the equipment, a molten salt (HTS)-turbine oil-air system was used. It was found that relatively large and thin solid shells could be produced and the diameter could be controlled easily. The geometric figures of solid shells produced here were of good spherical shape. Furthermore, the diameter, size distribution, shell thickness, aspect ratio and production frequency were measured for the wide injection gas conditions. Useful suggetions for the development of sequential solid shell production were presented.
