4.  Tablet Coating Equipment's
Three general types of equipments are available
 1.Standard coating pan
• e.g., Pellegrino pan system
• Immersion sword system
• Immersion tube system
 2.Perforated pan system
• e.g.,Accela cota system
• Hicoater system
• Glattcoater system
• Driacoated system
 3.Fluidized bed coater

5. 1.Conventional Coating Pans:
• It consists of a circular metal pan placed
angularly on a stand rotated on its horizontal axis
by motor .
• Heat is directed in the pan on the tablet bed
surface and is exhausted by means of ducts .

6. 2.Perforated pan system

An illustration of drying air movement and coating solution
a) Fig: Accela-cota System
As you can see, there are a number of processes that take place within the drum.
•Baffles ensure the tablets mix freely within the drum as it rotates
•Spray gun atomizes the coating solution and directs it to the tablets
•Dry inlet air flows from the upper section of the drum, passing in between the
tablets. It leaves the drum through the perforations.

7. A dria coater pan has hollow perforated ribs, which are locate on the inside
periphery tablet coating drum.
Therefore, as the drum rotates, the spray nozzle atomizes coating solution
and directs it to the tablets from the top section.

8. Although the design of hi-coater systems may be different, the working
principle is similar to that of the accela-cota.
The machine directs both the coating solution and drying air downwards.
The drying air, then leaves the coating system through the perforations
below the coating drum

9. The design of a Glatt coating pan machine resembles that of the accela-
cota.
This type of tablet coating machine is known for:
High spray rates
Extremely short processing time

11. 3. Fluidized Bed Coating Systems
• In fluid bed coating , particles are fluidized , coating fluid is
sprayed on and dried .
• 3 types :
• Top spray coating
• Bottom spray coating
• Tangential coating
