[0036] in, Figure 1Only the first driving pump 2 and the second driving pump 5 are schematically shown in the figure. Preferably, the first driving pump 2 and / or the second driving pump 5 may be a pulse pump.

[0037] Preferably, if Figure 1 As shown, the first syringe 3 may include a first pushing portion 31 and a first accommodating portion 33. For example, the first pushing portion 31 includes a first flange 32, and the first driving pump 2 drives the first pushing portion 31 through the first flange 32. The first accommodating portion 33 includes the first outlet 34.

[0038] Likewise, Figure 1 As shown, the second syringe 6 may include a second pushing portion 61 and a second receiving portion 63. For example, the second pushing portion 61 includes a second flange 62, and the second driving pump 5 drives the second pushing portion 61 through the second flange 62. The second receiving portion 63 includes the second outlet 64.

[0039] Preferably, the first syringe 3 and the second syringe 6 are fixed by fixing devices 13 respectively to facilitate the operation of the syringes.

[0040] Preferably, the first syringe 3 and the second syringe 6 are respectively provided with scales to facilitate the control of the granulation process.

[0041] Preferably, the capillary 8 may include a three-way connector (not shown), and the outlet end of the first connecting tube 4 and the outlet end of the second connecting tube 7 are respectively connected to the three-way connector, so that the first connecting tube 4 and the second connecting tube 7 are respectively connected to the capillary through the three-way connector.

[0042] Preferably, if Figure 1 As shown, the granulation device 1 further comprises a protective cover 9 surrounding the capillary tube 8 , and the protective cover 9 can protect and support the capillary tube 8 .

[0043] Preferably, the inner diameter of the forming tube 10 is substantially the same as the inner diameter of the capillary tube 8 .

[0044] Preferably, the flow rate of the fluid in the first connecting tube 4 is lower than the flow rate of the second fluid in the second connecting tube 7, so that the first liquid from the first syringe 3 is separated by the second liquid from the second syringe 6 in the capillary 8, thereby facilitating the first liquid to form a sphere.

[0045] Preferably, the sum of the inner cross-sectional area of ​​the first connecting tube 4 and the inner cross-sectional area of ​​the second connecting tube 7 is smaller than the inner cross-sectional area of ​​the capillary 8, and smaller than the inner cross-sectional area of ​​the molding tube 10. Therefore, the flow rate of the fluid in the capillary 8 and the molding tube 10 will be lower than the flow rate of the first fluid in the first connecting tube 4 from the first syringe 3, and lower than the flow rate of the second fluid in the second connecting tube 7 from the second syringe 6. Therefore, turbulence is not easy to form in the capillary 8 and the molding tube 10, which is conducive to the first fluid forming a spherical shape in the capillary 8 and the molding tube 10.

[0046] The granulation device 1 of the present application can produce granules 12 of uniform size.

[0047] For example, the first syringe 3 contains a marine polysaccharide solution, which is obtained by dissolving chitosan in a 0.5% hydrochloric acid aqueous solution, or by dissolving alginic acid in double distilled water. The second syringe 6 contains an isobutanol solution. The receiving container 11 contains a NaOH solution or a CaCl 2 Solution.

[0048] When in use, a pulse pump is used or the first and second driving pumps 2 and 5 are controlled in a pulsed manner, so as to alternately drive the first flange 32 of the first syringe 3 and the second flange 62 of the second syringe 6 in a pulsed manner, so that the marine polysaccharide solutions in the first syringe 3 and the second syringe 6 are driven to flow in a regular intermittent manner, respectively entering the capillary 8 through the first connecting tube 4 and the second connecting tube 7, and flow in the capillary 8 in an alternating manner. That is, in the capillary 8, the first fluid from the first syringe 3 and the second fluid from the second syringe 5 flow to the downstream forming tube 9 in an alternating manner. In the forming tube 9, due to the incompatible physical properties of the two liquids, the following is presented: Figure 1 The state shown is that the first fluid from the first syringe 3 forms a sphere, and between the spheres is the second fluid from the second syringe 5. When the spherical first fluid enters the receiving container 11, the first fluid reacts chemically with the receiving liquid, and the spheres gradually harden from the outside to the inside to form particles 12, and the second fluid is dissolved or dispersed in the receiving liquid. Therefore, in the capillary 8, the first fluid forms independent spherical micro-droplets under the shearing action of the second fluid, and in the capillary 8 and the molding tube 10, the second fluid carries the spherical first fluid into the receiving liquid, and after about 5 minutes, the spherical microspheres can be solidified, as shown in FIG. Figure 1 shown.

[0049] The granulation device of the utility model is simple to build and easy to operate, and can prepare microsphere particles with controllable particle size and uniform size.
