PURPOSE:To obtain a good seamless capsule by prolonging contact time of a liquid drop ejected from a nozzle with a solution for hardening. CONSTITUTION:A device, which forms the seamless capsule SC by forming a multilayer liquid drop while ejecting a multilayer liquid flow from a multiplex nozzle 7 and by bringing the liquid drop into contact with a solution for hardening, is used. The U-shaped groove 13 to supply the solution for hardening 10 and multilayer liquid drop to a vessel for hardening 14 is arranged tangentially to the cylindrical cross-section of the vessel for hardening 14 to cause the solution for hardening 10 in the vessel for hardening 14 to form herical flow 10A. As the result, the multilayer liquid drop descends while moving herically in the vessel 14 for hardening. |
