Dry granulation machine laboratory dry granulation machine for traditional Chinese medicine granules

Dry granulation is the process of using crystalline water in materials to directly degas, pre shrink, and press the material (powder) into thin sheets through hydraulic pressure. After being processed by a crushing system, graded dust removal and recovery processes, it is made into dry particles that meet customer requirements.

　　 According to the principle of mechanical extrusion granulation process, the prepared dry powder or fine crystal raw materials with a certain amount of crystal water are extruded into thin sheets, and then processed through the granulation system and screened into particles of the desired size.

Raw materials can be manually or vacuum fed into the hopper, transported and compressed by vertically placed feeding screws, and pushed to the bite angle of two extrusion rollers; Squeezing raw materials into thin sheets through horizontally placed rollers (the speed of the rollers determines the duration of the material's stay in the roller pressing zone); The pressure required for the material is linearly transmitted to the pressure roller through a hydraulic device, and the vertically arranged pressure rollers can ensure the consistency of material density. According to different particle size requirements, the mesh size of the sieve in the equipment granulation system can be replaced with each other.
