Extrusion–spheronization a promising pelletization

The extrusion–spheronization technique is the most popular method of producing pellets .This process was first reported by Reynolds and by Conine and Hadley and involves four steps: (i) preparation of the wet mass (granulation); (ii) shaping the wet mass into cylinders (extrusion); (iii) breaking up the extrudate and rounding of the particles into spheres (spheronization); (iv) and drying of the pellets .

The Spheronization Process

The design principle of the spheronizer is relatively simple but additions and adaptations are available have widened the range of applications and greatly improved the flexibility of the machines. For example, the Caleva "Twin" incorporates two spheronizers which allow continuous productions of spheroids.

An alternative to the multi-step extrusion-spheronization technique is rotogranulation, direct pelletizing, where spheroids are produced directly from powder. The powder is mixed and moistened in a single-unit spheronizing system consisting of a rotating disk. This disk provides a centrifugal force.

Granulation Method and Process Monitoring Matter

With extrusion/spheronization granulation, a pressure gradient force is used to wet or plasticize the mass through an orifice with a linear shear while in rotary granulation, a central rotating disk, rotating walls, or both create centrifugal or rotational forces that spheronize, agglomerate, and/or densify a wetted or non-wetted dry powder.

The Advantages of Spheronizing Pharmaceuticals

Spheronization, or Maramuerization, is a rapid and flexible process where pharmaceutical products are made into small spheres, or spheroids. Spheronized products are relatively dense, of a uniform in size and shape and have defined surface characteristics.

The second advantage of the Fluid Bed Systems is that not only coating but granulation and pellet formation is also possible in the same machine. Fluidized bed coating is a process that takes place inside a fluidized bed whereby a coat is introduced to cover the intended object in order to protect it or modify its behavior.

The compaction of powder by means of pressure roll can also be accomplished by a machine called chilsonator. Unlike tablet machine, the chilsonator turns out a compacted mass in a steady continuous flow. The powder is fed down between the rollers from the hopper which contains a spiral auger to feed the powder into the compaction zone.

The granulation may thus be in particular a wet granulation, a granulation with a meltable binder, a granulation by mounting with powders and/or liquids, a rotogranulation or a granulation by extrusion-spheronization. These main routes of granulation are based on the following principles: aggregation or mounting by spraying of powder or liquid.
