Cleaning processing method and apparatus for medical or medicinal rubber stopper

[0035] Example 1

[0036] See Figure 1, Figure 2 and image 3 .

[0037] The device shown in FIG. 1 is adopted, and its composition includes a container 1, a washing tub 2, a water storage bucket 13, a water inlet pipe 12, and a water outlet pipe 6. The container 1 is a cylinder with a diameter of D=800mm, the bottom and side walls of which are arranged with water spray holes 14, the diameter of the water spray holes D 1 =15mm, D 2 =40mm; the hole spacing D of the spray hole 3 =6mm, there are three reflux grooves 15 at the bottom of container 1, and the groove width is H 1 = 8mm. The clean water (deionized water) flowing out of the water storage tank 13 is pressurized by the water inlet pipe 12 and the booster pump 10, and then enters the container 1 and is sprayed from the spray hole 14 with a certain pressure liquid flow. The reflux tank is collected in the drainage tray, and returned to the water storage tank through the outlet pipe 6, the filter device 7, and the water pump 10 for

[0039] Example 2

[0040] The cleaning device and method are the same as in Example 1. Used for cleaning and processing double fork freeze-dried vaccine rubber stopper, each batch processing volume is 30kg. Geometry size of rubber stopper: d 1 =19mm; d 2 =13.5mm; h 1 =9.2mm. The cleaning time is 25 minutes. Table 2 shows the comparison between the test results of insoluble impurity particles on the surface of the obtained product and the rolling cleaning device and method.
