Abstract
A method of making a spherical seamless capsule formed by encapsulating a filler material such as a medicine with a capsule shell material shell such as gelatin. A liquid capsule shell material is stored in a tank at a low temperature, and supplied to a concentric multiple nozzle while it temperature is raised to a predetermined temperature upon being gradually heated while being transferred to the concentric multiple nozzle. This prevents deterioration in the capsule shell material and excessive decrease in its viscosity. When the liquid filler material and the capsule shell material flow out of the concentric multiple nozzle, their flows are cut by imparting a vibration thereto, to form a droplet in which the filler material and the capsule shell material are disposed at the center and on the outside, respectively. Such droplets are dropped into a curing liquid while in a dispersed state to cure the surface of the capsule shell material.
