ABSTRACT:
A method of manufacturing seamless capsules, wherein multi-layer liquid flow is blown out of a multiple nozzle to form multi-layer droplets which are brought into contact with hardening liquid to be solidified to thereby manufacture the seamless capsules SC and an apparatus therefor. A groove having U-shaped section for supplying the hardening liquid and the multi-layer droplets is orientated in a direction tangent to a circular section of a hardening vessel in the hardening vessel and a helical flow is formed in the hardening liquid in the hardening vessel, whereby the multi-layer droplets are fallen, moving helically in the hardening vessel.
