Because the wet granulation process is widely used in the pharmaceutical industry, it is used in almost all solid drugs. Therefore, the research on technology and the research and development of related equipment are also paid attention to by the pharmaceutical machinery industry.

Wet granulation is a method of preparing granules by adding liquid adhesive to the pharmaceutical powder and making the powder coalesced by bridging or bonding action of the adhesive. Due to its beautiful appearance, good fluidity, strong abrasion resistance and good compression formability, the product of wet granulation has been widely used in the pharmaceutical industry.

According to the introduction, wet granulation can make particles have good mobility, in drug delivery, packaging, filling and other aspects of easy to achieve automation, continuity, quantification; To prevent the separation phenomenon caused by the difference of particle size and density, which is conducive to the uniform mixing of various components; Prevent dust from flying and sticking on the wall during operation to avoid environmental pollution and loss of raw materials.

In addition, in the pharmaceutical industry, the application of wet mixed granulator improves the production efficiency, saves the labor cost, and makes the tablet production more scientific and stable. Due to the combined use of wet mixed granulator and tablet press, the annual sales volume of wet mixed granulator has a high market share.

With the development of the pharmaceutical industry, the requirements for pharmaceutical technology are becoming higher and higher. Therefore, wet granulation, which is more efficient, more environmentally friendly and safer, has been widely used. However, the market development is unpredictable, and the wet mixed granulator must keep its own advantages, constantly improve the deficiencies, strengthen the technical innovation, so that it can be better applied in the pharmaceutical field.
