Many people have difficulty swallowing tablets and capsules. These dosage forms can sometimes be too large, stick in one’s throat and taste or smell unpleasant. Instantised drinks, direct granulates, effervescent or chewable tablets and coated pellets, for example, can help to increase the user friendliness of the products for the patients. With the aid of fluid bed technology it is possible to produce such dosage forms with tailor-made attributes and in standardised quality.
Fluid bed technology involves drying a product in a processing chamber in a controlled environment. Heated, dehumidified and filtered air is passed into the plant’s material container from below, through a screen. This special bottom screen ensures that the air has specific flow characteristics. The starting substances are mixed homogeneously, and a fluid bed is created in which the particles are practically isolated and their entire surface is exposed to the medium to be added.
