Method for manufacturing seamless capsule

摘要

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