5 EXTRUSION and SPHERONIZATION – Pelletization Converts powder blends into pellets through the process of dry mixing, granulation, spheronization and drying The pellets or granules of active materials are generally small, free-flowing, spherical units called pellets, beads or sometimes microspheres Generally materials are made up of multiple BOTTOM SPRAY- The bottom-spray (Wurster) fluid-bed method is very popular in the pharmaceutical industry for drug layering and for coating to modify or control drug release. The hot air is passed through the fluidized bed, particulate material are lifted in air stream, solution/suspension sprayed on fluidized bed for granulation and coating. There are three types off granulations as dry granulation, wet granulation, and direct mixture. The main difference between bare furthermore wet granulation is that dry granulation is the formation of granules without using any liquid solution whereas wet granulation lives the formation of granules by adding a granulating liquid. Key Scope 3. • Pelletization is an agglomeration process that converts fine powders or granules of bulk drugs and excipients into small, free flowing, spherical or semi spherical units, referred to as pellets. In addition, pellets have numerous therapeutic advantages over traditional single units, such as tablets and powder-filled capsules.
Melt pelletization of lactose in an 8 litre high shear mixer was examined by a factorially designed experiment. Polyethylene glycol (PEG) 3000 was used as melting binder in a concentration of 23% m/m. The load of the mixer was varied at 600, 800 and 1000 g of lactose.

A Model of agglomerate formation during bed wetting in the process of disc granulation. Andrzej Obraniak T. Gluba. Materials Science, Engineering. 2012. This paper presents a method for quantitative assessment of the mechanisms of nucleation and granules growth by layering in the process of bed wetting during periodic disc granulation.
Granulation tissue is the primary type of tissue that will fill in a wound that is healing by secondary intention. It is made up of macrophages, which help to remove debris and release cytokines. Cytokines help to activate fibroblasts, which will make collagen, trigger endothelialization, and help with the formation of new blood vessels, a xmCu.
