Granulation is the operation of processing materials such as powders, melts, aqueous solutions, and the like to produce granules having a certain shape and size. Almost all solid preparations can not be separated from the granulation process. The granulate produced may be the final product, such as granules; it may also be an intermediate product, such as a tablet. Granulators produce the desired particles faster and more efficiently in a machine-operated manner. The granulation methods mainly include wet granulation, dry granulation and agitation granulation. Granulators mainly consist of feeding, stirring, granulating, transmission and lubrication systems.
The application range of wet granulator is gradually expanding. The wet granulator is a granulating device that has been developed relatively rapidly in recent years. The two-step process of mixing and granulation is combined in the process, saving both time and satisfaction. The GMP requirements reduce cross-contamination and improve efficiency. It is a quick and easy way to save and is welcomed by users. Wet granulator is suitable for the mixing of powder and powder, granulation of powder and binder in the pharmaceutical, chemical, food and other industries. The whole machine consists of programmable control (man-machine interface - option), unified process, to ensure stable quality, manual operation can also be carried out, easy to explore process parameters and processes.
Wet granulator can develop wet powder into desired granules, and can also crush lumps of dry material to desired granules, mainly by airframe, granule manufacturing device, screen clamp, gearbox, and machine. It is composed of several parts such as a motor, which has the advantages of easy disassembly and easy cleaning. In addition, the mechanical transmission system is completely enclosed in the body to ensure the safety of the granulation process.
In production, the application of wet mixing granulator improves production efficiency, saves labor costs, and makes production more scientific and stable. Due to the use of the wet mixing granulator and the tablet press, the sales volume of the wet mixing granulator has a high market share throughout the year.
In the era of new development, China’s overall national strength has been greatly improved, science and technology have advanced by leaps and bounds, and it has gradually reduced its level with advanced countries in the world. In a good domestic atmosphere, the scope of application of wet granulators in China is gradually expanding and the development prospect is bright.
Dry granulator development requirements The dry granulator is the latest granulation method developed after the "step-granulation" of the second-generation granulation method. It is an environmentally-friendly granulation process that directly suppresses the powder. Granulated new equipment. Dry granulator is widely used in granulation in the pharmaceutical, food, chemical and other industries. It is especially suitable for granulation of materials that are susceptible to heat decomposition, decomposition or agglomeration. The pellets produced by the dry granulator can be directly compressed or filled into capsules.
It is understood that the dry granulator uses the latest roll control technology. The control equipment of the equipment can adjust the fluctuation of any physical property between different materials and batches of the same material, so that the dry granulation process parameters can be accurately and repeatedly To adjust to efficiently produce high quality particles. The dry granulation technique can be accomplished by a roller flattener. The Chinese herbal extracts with a certain relative density were spray-dried to obtain dry extract powders. After adding certain auxiliary materials, they were pressed into a sheet by a dry extruding granulator and then crushed into granules. The method requires less auxiliary materials, which helps to improve the stability, disintegration and dissolvability of the particles.
In the future, dry granulators will meet the requirements for cleanliness and functional flexibility. First of all, for a completely enclosed dry granulation system, dust pollution during production can be reduced, thereby reducing the risk of contamination and pollution. Secondly, the equipment is modularly designed and the whole granulation device can use only a few tools. Detachable, easy to clean all modular units, and can easily replace the screw and the pressure roller to adapt to different granulation tasks.
At present, the market competition for food machinery and equipment is becoming increasingly fierce. China's granulation machine companies want to stand out among many manufacturers, and should base themselves on science and technology, absorb and introduce advanced technologies at home and abroad, and constantly research and develop new products to meet the ever-changing market demands.
