R&D Tablet Coater

R&D TABLET COATER

A revolutionary self-contained film coater is adapted to handle smaller trial batches of tablets and granules. The Pharma R & D tablet coating machine has elegant exterior fabricated of SS 304 box with coating pan supported in a tangential position of 35° to 45°.

Coating small batches of the tablets and granules.

REQUIREMENT

Research and development department of pharmaceutical companies had to manufacture unnecessary quantities of test drugs due to existing standards coating facilities which is resulted in huge wastage of effort as well as money.

SOLUTION

The new R & D tablet coating machine is designed to fulfill the specific need, with the help of unique array of smaller coating pan sizes of 4” & 6” which ensures the quantity of the test batch never exceeds the requirement.

FEATURES

The R & D tablet coating machine has the exterior appearance of an elegant fabricated box with coating pan supported in a tangential position of 35° to 45°. The entire drive mechanism is concealed with the box leaving only the hub, supporting the coating pan, projected outwards to enable vertical rotary momentum.

The R & D Coater is an integrated and semi-automatic unit consisting of stainless steel coating pan, a spraying system, a hot air blower, and an exhaust system. It uses the rotary momentum of the coating pan to tumble the tablets/granules contained within it. Baffles are provided along the interior walls of the pan to tilt the contents for efficient coating.

As film coating requires a spray technique, a spray gun delivers finely nebulized droplets of the coating solution onto the moving bed, in such a manner as to ensure uniform coverage. The tablets are dried by directing a stream of hot air onto the surface of the tablet bed and the exhaust between 60°C- 80°C, to achieve better performance. All the setting, including the temperature and rotation speeds can be measured and adjusted accurately using the advance control panel. Feeding and retrieving the tablets/granules from the pan should be done with scoop, and the various parameters for coating should be established through trials.

Tablet Coater R&D Model (small coating pan) uses for sugar/film coating onto tablets. All contact parts are made from Stainless Steel 316L, or FDA approved materials for cGMP compliance.

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 consist 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.
