Description

Technical Field

[0002] Freeze-dried powder is a sterile powder injection made by freezing the liquid medicine into a solid state in a sterile environment and then sublimating the water to dry it in a vacuum. Freeze-dried powder is made by pre-freezing the water in the liquid medicine using a freeze dryer, and then sublimating the frozen water in the liquid medicine in a vacuum sterile environment to obtain freeze-dried powder. In short, the water in the liquid medicine is evacuated in a low-temperature environment to retain its original medicinal effect.

[0003] During the production process of freeze-dried powder, it is often necessary to detect the humidity inside it in order to better ensure its production and subsequent use, and it needs to be filtered and screened during the production process in order to ensure the production quality of the freeze-dried powder. The structure of the existing freeze-dried powder filtering and screening device is too simple, which makes the screening efficiency of the freeze-dried powder low and the screening effect poor, thereby affecting the production efficiency of the freeze-dried powder and failing to meet the actual production needs of the freeze-dried powder; and when the humidity of the freeze-dried powder is high, it is easy to adhere to the filter membrane, which causes the screening of the freeze-dried powder to be greatly affected, and the existing filtering and screening device does not have a mechanism for detecting the humidity of the freeze-dried powder, which is not conducive to the filtering and screening production of the freeze-dried powder.

[0004] In this regard, the Chinese patent application number is CN201922337306.7, which discloses a filtration and detection device for freeze-dried powder, including a cylinder, a discharge hopper fixedly connected to the bottom of the cylinder, a discharge pipe fixed at one end of the discharge port of the discharge hopper, and a processing bucket fixed through the top of the cylinder. The freeze-dried powder inside the sieve cylinder is stirred by a motor driving a plurality of stirring rods on the flange, thereby promoting the filtration of the freeze-dried powder. At the same time, the cooperation of the processing bucket, the first blower and the second blower further promotes the filtration and screening of the freeze-dried powder, thereby further improving the filtration and screening efficiency of the freeze-dried powder, thereby better meeting the actual production and processing needs of the freeze-dried powder.
