The working principle of high efficiency mixing wet granulator: SFZL-5high-efficiency mixed wet granulator is a new-generation wet mixing granulator newly developed by our company. It has adopted a large number of new technologies based on the original granulation at home and abroad. It has reasonable structure, convenient use and function. Perfect features. High-speed mixing granulator features: 1.It adopts horizontal cylinder structure and has reasonable structure; 2, inflatable seal drive shaft, can be switched to water when cleaning; 3, fluidized granulation, granulation is approximately spherical, and the fluidity is good; 4, reduce theadhesiveby25%compared with the traditional process, and shorten the drying time; 5, each batch is dry mixed for2minutes, granulation for1-4minutes, the work efficiency is4-5timeshigher than the traditional process; 6, completed in the same closed container, dry mixing-wet mixing-granulation, process reduction, in line withGMPregulations; 7. Theentire operation has strict safety protection measures.
Common methods and characteristics of high-speed mixing granulator: Granulation is often carried out by wet granulation, one-step granulation and dry granulation.Granulation is a process in which a powder of a raw material and a binder are mixed into a soft material, and the particles are dried.However, the soft material is traditionally made of a soft material made of a trough mixer and then wetted by a rocking granular mechanism. However, it is dried into a dry granule by a drying box. This method has low yield, high strength, serious pollution, and long production cycle. The equipment covers a large area.Recently, it has been gradually replaced by a continuous production operation method of a high-speed mixing granulator and boiling dry granulation or a one-step granulation method.
Functional requirements for high-speed mixing granulators: 1. Mix the paddle to dry mix the material, add the binder and mix it wet.According to the characteristics of the material and the adhesive, the rotation speed of the stirring paddle ensures that the motion generates eddy current and the material is thoroughly mixed.At the same time, the mixing area of the granulating knife completely breaks up the tumbling material mass into granules; 2 , the rotation speed of the stirring paddle and the granulating knife can make the material produce three-dimensional motion, the particles collide, rub and shear, make the friction uniform and detailed, and shape stable spherical particles.The mixing time, the speed of the stirring paddle and the granulating knife, the granulation quality and the uniformity after drying satisfy the requirements of the production process of the solid preparation; 3 , the process should be in a closed state, the whole process of mixing granulation (including feeding, mixing, cutting granulation and unloading, etc.) should work under100,000 or 300,000 class cleanliness, and ensure that no foreign matter falls;
4 , the machine can be connected with boiling drying or lifting feeding or vacuum feeder equipment.
