Dry granulating machine is the second generation of granulation method "one step granulating" developed a new method for granulating, pelleting process is a environmental protection type, directly to the new equipment powder pressed into a pellet. Dry granulation of the pharmaceutical industry involved in various active pharmaceutical raw materials and processing one or more excipients, these raw materials are mostly fine powder, and the powder particle size is not a, uneven density, not good fluidity, easy molding. Therefore, must be a key granulation process, can be carried out under the tablet, capsule filling or raw materials directly packaging in the form of particles.
Dry granulating machine using the latest rolling control technology, control equipment, the equipment can adjust different materials and the volatility of any physical properties of the same material between different group, the process parameters of dry granulation can be accurate, repeated adjustment, so as to efficiently produce high quality particles. Dry granulation technology by roller press granulating machine. With traditional Chinese medicine the relative density of extract, the spray drying to obtain dry extract powder, add some accessories, to squeeze dry granulating machine pressed into thin slices, and then crushed into particles. The method needs less materials, is helpful to improve the stability of the particles, disintegration and soluble powder.
Dry granulator and then through the rock particles mechanism of grain. Process simple, particle out can directly use, does not require drying, save manpower, can greatly improve the work efficiency. Do not need to add other adhesives, compared to the sticky material, solves the conventional wet do not come out, there are some materials, material requirements can add other adhesives, in order to solve these kinds of wet can not solve the problem, is also a good way to feasible. Dry granulating machine in the production process of low temperature rise, very suitable for heat sensitive materials.
Dry granulating machine he used the stirring paddle will powder and adhesive mixed wettability of soft material, and by the high speed crushing knife cut into wet "soft wood grain", at present the method commonly used. The equipment and technology is not perfect: it needs a great deal of adhesives, cleaning the sewage pollution on the environment. In addition, the wet particle mesh wide distribution and not uniform, fine powder, usually used for pressing goods capsule filling. Intermediate improves the quality of the product made of uniform particles, pine is suitable, the particle size distribution is narrow, round shape, good fluidity, particles can be prepared by the small color difference, the required particle.
Future, dry granulating machine will meet the clean and flexible functional requirements. First of all, as the dry granulating system is completely closed, can reduce the dust pollution in the production process, thereby reducing the risk of pollution and pollution; secondly, the equipment adopts a modular design, the granulating device can only use a small amount of tools can be disassembled, convenient for cleaning of all the modules, and can be easily replaced screw and a pressure roller which adapt to different tasks. |
