- the upper part of Separation 23 is made of perforated plates or nets.
- Sieve plate 24 is arranged at an angle. Since the size of the sieve plate 24 is smaller than the outer diameter of the sheathless capsule, when the hardening liquid and the seamless capsule flow into the separator 23, the hardening liquid passes through the sieve plate 24 and separates from the separator 23.
- the seamless capsule rolls on the sieve plate 24 and falls through the gutter 25 into the collection container 26, where it is stored.

- the gelatin solution is stored in the gelatin tank 5 at a high temperature of, for example, 80 ° C. Over time, the molecular structure becomes smaller and deteriorates, and the viscosity also drops significantly. If this is allowed to flow out of the concentric multi-nozzle 4 as it is, the molded state of the seamless capsule will be deteriorated, and a large number of defects such as eyes, eccentricity and irregular shapes as shown in Figs. The strength of the film formed by the hardening of the steel also deteriorates.
- the gelatin solution is stored in the tank 5 at normal temperature, guided into a heating tank, and heated here overnight to quickly raise the temperature to about 80 ° C. After that, it was proposed to supply the concentric multiple nozzles 4.
- the temperature of the gelatin solution is raised from room temperature to about 80 ° C, not only a local temperature deviation and a local change in physical properties are easily generated in the gelatin solution, but also the concentric multi-nozzle 4 It is difficult to keep the temperature and viscosity of the supplied gelatin solution constant.
- the gelatin solution is stored in the gelatin tank 5 at a temperature that does not affect the physical properties of the gelatin solution, that is, at least a temperature that does not change the molecular structure, for example, 50 ° C.

- the gelatin solution is heated to 70 ° C. to 90 ° C. by heating while being transferred to the concentric multiple nozzle 4.
- the gelatin solution is supplied to the concentric multi-purpose nozzle 4 and immediately flows out therefrom, so that the physical properties such as temperature and viscosity of the gelatin solution flowing out of the concentric multi-nozzle 4 can be kept constant. it can.
- the gelatin solution is gradually heated while moving through the inner tubes 14 a, 16 a, 17 a of the double tubes 14, 16, 17 and the spiral tube 6 a of the intermediate heater 6, Since the temperature rises with a substantially constant temperature gradient, local temperature deviations and changes in physical properties are prevented. In addition, the temperature of the gelatin solution is raised only during the transfer from the gelatin tank 5 to the nozzle 4. —Because the time is constant, the gelatin solution shows certain physical properties when it reaches the concentric multiple nozzle 4. In addition, heating during transfer is for a short time, Excessive reduction and deterioration of the gelatin solution can be prevented. As a result, it is possible to prevent the seamless capsule from having defects such as eyes, eccentricity, irregular shape, and warp, and it is possible to stably produce a high-quality seamless capsule for a long time.
- the intermediate heater 6 is interposed between the double pipe 16 and the double pipe 17, the length of the double pipes 14, 16, and 17 is reduced, and accordingly, the device The gelatin solution is heated while moving in the spiral tube 6 a of the intermediate heater 6, so that the gelatin solution does not stay in the intermediate heater 6. That is, long-term heating is prevented.
- the gelatin solution flows out immediately after flowing into the concentric multi-nozzle 4, so that there is almost no temperature drop and the gelatin solution flows out with a desired viscosity.
- This combined with the action of the movable wall 4d provided on the concentric multiple nozzle 4, contributes to the production of a seamless capsule of stable quality and dimensions. That is, the vibration of the movable wall 4d is transmitted through the chemical solution to the merged flow of the drug solution and the gelatin solution flowing out of the concentric dodge nozzle 4, so that the merged flow is sequentially cut off from its tip. Since the viscosity of the gelatin solution is kept almost constant, the shredding can be performed reliably at a desired position.
- the amplitude and frequency of the vibration applied to the movable wall 4d can be easily adjusted by the vibrator 11, the size of the droplet and the number of droplets per unit time can be easily adjusted. can do. As a result, it is possible to greatly improve the production capacity of the seamless capsule without causing any defect in the seamless capsule and without increasing the weight of the seamless capsule or the variation in the filling amount of the chemical solution.
- the movable wall 4d is installed above the room 4c to define a part of the room 4c, and can be moved up and down.
- the propagating pulsating wave can be effectively transmitted without being attenuated to the combined flow flowing downward from the concentric multiple nozzle 4.
- the vibrator 11 since it is sufficient for the vibrator 11 to vibrate only the movable wall 4d up and down, the vibrator 11 can be used with a simple structure, small size and inexpensive. Simple connection structure between 1 and movable wall 4d, small Since it is compact, inexpensive, and does not vibrate peripheral equipment, it is possible to prevent unnecessary and harmful vibrations from adversely affecting the seamless force cell.
- good droplets are formed from the concentric multi-nozzle 4, but the droplets are cured by contact with the curing liquid to complete a seamless force capsule. Insufficient curing may cause problems such as deformation of the seamless capsule, adhesion and cohesion of seamless capsules, and damage to the coating of the seamless capsules. In order to sufficiently cure the droplet, it is necessary to take a sufficient contact time with the curing liquid. However, if the droplets are retained in the curing liquid in order to prolong the contact time, the droplets may adhere to each other and agglomerate to break the film of the seamless capsule or deform the seamless capsule.
- the curing speed of the droplets is also reduced. Need to be prevented. This prolongs the time interval between the dropping of the droplets and reduces the production capacity of the seamless capsule. Further, if the transport distance of the droplets by the squeezing liquid is increased, the size of the apparatus may be increased and the cost may be increased.
- droplets formed by cutting the combined flow flowing out of the concentric multi-nozzle 4 are cooled in the process of moving through the forming tube 20, the curing tank 21, and the transfer tube 22.
- the droplets disperse into the curing liquid in the curing tank 21 from the opening 20a of the forming tube 20 and slowly descend to form a circular trajectory.
- the distance between the droplets in the vertical direction is wider than when the droplets are dropped from the position, and the possibility that the droplets come into contact with each other and adhere and condense is reduced.
- the term “dispersion” means that the descending path of one droplet and the descending path of the next droplet are spaced apart in the horizontal direction.
- the transport distance of the droplet in the curing liquid should be shortened, that is, the forming tube 20, the curing tank 21, and the transportation tube 22 should be reduced in size. Since the length can be shortened, it can contribute to miniaturization of the device as a result. Furthermore, since the time interval between the dropping of the droplets can be shortened, it contributes to the improvement of the manufacturing efficiency.
- the preferred embodiment of the present invention has been described above, but it is needless to say that the present invention is not limited to the above embodiment.
- the illustrated concentric multi-nozzle 4 has a double structure including a central nozzle 4a and an annular nozzle 4b surrounding the central nozzle 4a, but a plurality of annular nozzles concentric therewith around the central nozzle 4a. Can be used. Further, if the liquid is caused to flow out from only one of the center nozzle 4a and the annular nozzle 4b, a single-component seamless capsule can be manufactured.
- a movable wall 4 d is provided above the concentric multi-nozzle 4 to vibrate the chemical solution, but instead, the gelatin solution may be vibrated. Vibration may be applied to both the drug solution and the gelatin solution in synchronization.
- the movable wall may have any shape and structure as long as it defines the chemical flow path and the Z or gelatin solution flow path in the concentric multiple nozzle 4 for the chemical liquid. It is desirable to provide it near the heavy nozzle 4.
- the forming tube 20 is rotated about a vertical axis, and the curing liquid flows out along with the droplets from the opening 20a in the horizontal direction. It is placed in the upper part of the liquid in the curing tank 21 near the outer periphery, and together with the curing liquid from the opening in the tangential direction of the curing tank 21 and in the horizontal direction.
- the curing liquid in the curing tank 21 can be swirled, and the trajectory of the droplet placed on the swirling flow draws a spiral.
- the gelatin solution is sufficiently hardened, and only the hardening liquid in the hardening liquid stored in the hardening tank 21 is tangentially and water-cooled.
- the hardening liquid in the hardening tank 21 can be swirled by flowing in a horizontal direction.In this case, the forming tube is omitted and the lower end of the concentric multi-nozzle 4 is hardened in the hardening tank 21. What is necessary is just to immerse in a liquid.
- the combined flow from the concentric multi-nozzle 4 may be discharged into the atmosphere to form droplets in the atmosphere, and the droplets may be dropped on the surface of the curing liquid swirling in the curing tank 21. it can.
