Litco COATER is an automated tablet coating system for efficient film and / or sugar coating of tablets with cGMP compliance in closed condition .The main Pan unit consist of a cylindrical perforated pan with conical ends in a SS double- walled enclosure. Tablets to be coated are charged into the pan.  During the coating process, coating fluids are sprayed (film coating) through multiple Air borne Spray Gun (s) mounted with in the pan.  Alternatively, the sugar syrup may be administered through the front opening with the dosing assembly.  A peristaltic Pump is employed for precise delivery of coating fluids / or, sugar syrup.  The tablet bed is gently and efficiently mixed during pan rotation with the aid of mixing baffles attached internally, with in pan.  The coated tablet cores are dried with heated air supplied from an Inlet AHU – which Contains a Heating system as well as Sequential battery of EU-2, EU-4, EU-7 and EU-13 Micron filters.  As a result, applied coating is dried with non-contaminated, dust-free and optimized volumes of air, for producing uniformly coated tablet cores. 


1.Cylindrical Pan


AISI 316, Perforated 48" / 915 mm. with 3 mm holes. Rotated by 5HP motor with a suitable gear box at 2 to12 through VFD.


AISI 316, Rabbit Ear type alternately placed to ensure proper mixing and avoid any dead areas. Total 4 nos. of baffles are placed with in the Pan.

3. Sensors

To sense measure and transduce temperature / pressure /flow measurement for display and / or regulatory-indication & interlock function.

4. Sink

Collects wash water / solution during washing and enables rotating perforated pan / drum to run through collected wash water in sink.  The latter is provided with pipe with valve assembly, for draining water after wash cycle.

5. Coating application system

It contains 50Ltrs. AISI 316/ 304 (Non-contact) Solution vessels with a pneumatically oscillating agitator mounted on top lid for Solution holding

6.  Spray Guns

Spray System USA make 2 nos. 1 mm needle with provision for setting span of the spray.

7. Tank weigh system (optional)

Tank will be mounted on electronic platform balance connected to the PLC for monitoring spray rate by weight.

8.Peristaltic Pump

Electrically operated peristaltic pump is incorporated in the unit.  The Silicon Tubing passes through the pump, of which one end is dipped into the solution tank and the other end is connected to coating / or dosing manifold.
