Tablet Coating Pan

Tablet Coating Pan

Tablet Coating Pan (conventional coating pan) including Tablet coating system is cGMP machine designed for coating tablets. Coating Pan Machine  designed from MS fabricated structure with SS coverings electric control, air filter and SS Pan inside the enclosure, which makes simple cleanable outside covering. Machine is mounted on dynamounts which avoids foundation.

Coating Machines are provided with interlocked electrical circuit so that heaters operated only after blowers switch ‘on’ to avoid burning of hearts. Coating SS Pan Mouth ring is soldered at their rim cavities to avoid collection of dirt or contaminated drug. Standards machine with helical Gear Box, induction Motor and all electrical controls made of well known brands. Thermostat control can be provided on demand. On customer demand, Gear Box and electricals including motors can be flameproof/explosion proof. We manufacture Coating Pans ranging from 8 inch Small Coating Pan to 48 inch Industrial Coating Pan.

Design and Construction of Tablet Coating Pan

PAN: The Coating Pan is Semi Ellipsoidal size pan with a circular mouth for charging & discharging of tablets, Pan mounted at an inclination of 45 degrees to the horizontal.

DRIVE ASSEMBLY: The tablet coating pan consists of a suitable 3 Phase, 440 V, 1440 RPM TEFC motor with suitable worm reduction gear box and cone pulley arrangement to give three speed output.

HOT AIR BLOWER: The tablet coating pan unit is provided with a hot air blower consisting of suitable 3 Phase 440 V, 2880 RPM TEFC electric motor & centrifugal blower with damper delivering required CFM. The air is heated by means of suitable electric heater to give air at 30 to 90 degrees Heater with thermostat control and flexible hose pipe.  

CONTROL PANEL: Unit provided with suitable control panel with starters and push button to actuate the drive and for blower The circuits consists of MCCBs, relays and contractors in series Ample overload protection is provided by the MCCB and the relay Wires coming out of the connections are numbered for easy recognition.

MOUNTING: The motor and gear box is mounted inside sturdy MS frame and the pan mounted on the Gearing housing fitted in the stand. Blower mounted by the side of the stand or placed in remote location if required.

FINISH: All joints argon Arc welded and all SS Parts polished to suitable finished required of pharmaceutical equipment MS parts painted to smooth finish.

 

Working Principle of Tablet Coating Pan

The sterilized powder is stored in powder hopper is agitated by pair of mechanical agitators for maintaining consistency and uniform bulk density. The powder wheel having twelve ports which rotates at pre-determined speed below the powder hopper with practically no clearance. Powder wheel consist of Piston in each port and behind the powder wheel vacuum plate is provided. There is no clearance between powder wheel and vacuum plate due to back spring pressure. Precise volume of powder is sucked into the port of powder wheel during vacuum; according to the piston length different fill size can be achieved. The excess powder is doctored off by a doctor blade. Doctor blades can be adjusted from outside also without removing powder hopper. When powder wheel indexes further and remain in the port due to the vacuum till it reaches just vertically above the container. The time dose of Compressed air (Nitrogen Gas), sterilized low pressure air sequentially flushes out powder from the port of powder wheel in to the container one by one.

The filled containers are immediately separated on the conveyor by vial separator and moves further for stoppering operation.

The sterilized, siliconised, rubber stoppers stored in the vibrator bowl moves to vibratory bowl and stacked vertically in the rubber stopper chute. The container is hold firmly between pair or timing belt to pickup rubber stopper from exit end of the chute. Further container is passed between two pressing roller for tight fit fixing of rubber stoppers.
