Description

Technical Field

[0001] The utility model belongs to the technical field of freeze-dried powder processing and relates to a freeze-dried powder auxiliary material mixer. Background Art

[0002] Freeze-dried powder is made by pre-freezing the water in the liquid medicine using the vacuum freeze drying method of a freeze dryer, and then sublimating the frozen water in the liquid medicine in a vacuum sterile environment to obtain freeze-dried powder. When processing freeze-dried powder, in order to increase the nutritional content, auxiliary materials such as peptides and collagen are added, so a mixer is used for mixing.

[0003] A freeze-dried powder auxiliary material mixer disclosed in Chinese patent CN219168247U includes a fixed seat, a mixing tank is rotatably connected to one side of the fixed seat, a feeding pipe is arranged on the top of the mixing tank, a rotating rod is arranged inside the mixing tank, the side wall of the rotating rod is rotatably connected to the side wall of the fixed seat, a forward motor and a reverse motor are respectively arranged on the side wall of the fixed seat, the output end of the forward motor passes through the fixed seat and is fixedly connected to the mixing tank, the output end of the reverse motor passes through the fixed seat and is fixedly connected to the rotating rod, and the outer wall of the rotating rod is evenly fixedly connected with a stirring rod.

[0004] When the mixer is in use, the forward motor drives the mixing tank to rotate, and the freeze-dried powder excipients inside the tank are preliminarily mixed. Then, the reverse motor drives the rotating rod to rotate in the opposite direction of the mixing tank, thereby driving the stirring rod to perform secondary mixing of the freeze-dried powder excipients inside the tank. The mixing tank is horizontally arranged. When rotating, part of the excipients located at both ends of the mixing tank will continue to rotate at both ends of the mixing tank, resulting in a poor mixing effect. Moreover, when adding materials, all the excipients need to be added through the feed pipe, and then the feed pipe needs to be sealed for stirring. Therefore, the added excipients will pile up together, and the subsequent stirring will mix the excipients, increasing the mixing time.

[0005] In order to solve the above problems, the utility model proposes a freeze-dried powder auxiliary material mixer. Utility Model Content
