Abstract
A seamless capsule manufacturing apparatus (1) manufactures a seamless capsule by means of nozzles (2a-2d). A core liquid (5) and a coating liquid (6) are supplied to each of the nozzles (2a-2d) from pumps (16, 18) through distributors (21, 22). The distributors (21, 22) and the nozzles (2a-2d) are connected to each other by core liquid distributing tubes (23a-23d) and coating liquid distributing tubes (25a-25d), and each of the core liquid distributing tubes (23a-23d) and each of the coating liquid distributing tubes (25a-25d) have the same length. A vibrator (24) is mounted to the distributor (21), and the core liquid (5) is supplied to the nozzles (2a-2d) while being vibrated. Each of the distributors (21, 22) is provided with an air vent device (35), and air vent is performed appropriately.
