- Granulation is
the process of collecting particles together by creating bonds
between them. Bonds are formed by compression or by using
abinding agent. If one were to make tablets from granulated
sugar versus powdered sugar, for example, powdered sugar would
be
difficult to compress into a tablet and granulated sugar wouldbe
easy to compress
- Wet
granulation, the process of adding a liquid solution topowders,
is one of the most common ways to granulate. The
process can be very simple or very complex depending on the
characteristics of the powders, the final objective of tablet
making,and the equipment that is available.
- In a Fluid Bed,
a product or solid is made fluid by an upward-moving flow of
gas. The mechanical movement of the Fluid Bed strengthens this
effect. Thus, the gas and product are intensively mixed, so that
high heat transfer and an optimum physical reaction speed are
achieved. By choosing a good combination of gas speed and
mechanical movement , one can process granular products with a
wide range of grain sizes successfully while forming a minimum
amount of dust.
- Fluid bed
drying is one of the most efficient drying methods available.
Advanced fluid bed technologies offer much more opportunities:
By spraying liquids ontothe solids, a variety of innovative
processes like granulation, agglomeration, coating and micro
encapsulation can be realized.
- Silica gel is
produced synthetically from sodium silicate, which is a porous
but granular form of silica. It is utilized as a desiccant or
moisture adsorbent to manage humidity levels locally in order to
avoid degradation of the goods
- The principal
desiccants used in
pharmaceutical applications are silica gel and molecular sieve.
Silica gel is available in two main types: awhite,
non-indicating version and one that changes colour when moisture
is adsorbed.The latter is obviously useful to indicate when the
desiccant is used up.
