Regranuláció

Regranuláció is a process used in various industries to convert granular or powdered materials into larger, more uniformly sized granules. This transformation is often achieved through methods like wet granulation or dry granulation. In wet granulation, a binder solution is added to the powder, creating a paste that is then forced through a sieve to form granules. These granules are subsequently dried. Dry granulation, on the other hand, involves compacting the powder into larger pieces, which are then milled into granules. The primary purpose of regranulation is to improve material properties such as flowability, compressibility, and bulk density, making them easier to handle, process, and formulate.

This process is widely employed in the pharmaceutical industry to produce tablets and capsules. By improving the flow characteristics of active pharmaceutical ingredients and excipients, regranulation ensures accurate dosing and consistent tablet formation. In the food industry, it can be used to create instant beverage mixes or to improve the texture and handling of powdered food products. The agricultural sector also utilizes regranulation for fertilizers and pesticides, enhancing their application and effectiveness. The specific equipment and parameters used in regranulation vary depending on the material properties and the desired granule characteristics.
