drying is a commonly used method of drying a liquid feed through a hot
Typically, this hot gas is air but sensitive materials such as
pharmaceuticals, and solvents like ethanol require oxygen-free drying
and nitrogen gas is used instead.
liquid feed varies depending on the material being dried and is not
limited to food or pharmaceutical products, and may be a solution,
colloid or suspension. This process of drying is a one step rapid
process and eliminates additional processing.
company in Denmark is the leader in spray drying technology,
commercially as well as technically.
types of atomizers are used in industrial drying: Rotary , Pressure
Nozzle, Two - fluid nozzle.
choice of atomizer depends upon the properties of the feed and the dried
application of new techniques in spray drying of final product gives
excellent control of particle size in API production.
drying is presently one of the most exciting technologies for the
pharmaceutical industry, being an ideal process where the end-product
must comply to precise quality standards regarding particle size
distribution, residual moisture content, bulk density and morphology.
widely used for the manufacture of many consumer and industrial products
such as instant food, laundry detergents, ceramics and agrochemicals,
the growth in pharmaceutical spray drying was driven by a number of
advantages over conventional multiple-step processes and competing
particle reduction technologies.
