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.

COATING PAN

Coating pan has been made from pure SS 304/SS 316 quality material, it consists of central cylindrical portion. Opening front side known as “pan mouth”. Baffles are

provided along the interior walls for efficient coating. The pan is detachable and available in an array of sizes 4” and 6”. Pan rpm can be set from 3 to 100 rpm

HEATER

The heater heats the inlet air at the desired temperature required to dry the tablets. It can be controlled to deliver the air at 30 C (ambient) to 80 C.

EXHAUST PIPE

Unwanted fumes and dust (generated by core tablets & coating material) can be cleared through the exhaust pipes from the coating pan.

AIR FILTER & CONTROLLER

It filters and removes moisture coming from compressor and also controls the flow rate. We can set air pressure in psi or bar.

CONTROL PANEL

Advanced control panel offers complete control over the various setting for the coater.

SPRAY GUN

Spray gun delivers droplets of the coating solution onto the tablet bed. Its superb performance is achieved by the use of a new range of nozzles made by pure SS 304/SS 316 & metered

PERISTALTIC PUMP

Peristaltic pump delivers exact amount of coating solution to the spray gun through silicon pipe dozing with the help of a peristaltic pump. It is easily adjustable along with its stand.

The R&D Coater is a versatile and semi-automatic unit designed for pharmaceutical research and development. This integrated system comprises a stainless steel coating pan, a precision spraying system, a hot air blower, and an efficient exhaust system. It harnesses the rotary motion of the coating pan to gently tumble the tablets or granules contained within it. Inside the pan, strategically placed baffles tilt the contents to ensure uniform and efficient coating.

For film coating, a specialized spray gun is employed to disperse finely nebulized droplets of the coating solution onto the moving bed, ensuring consistent coverage across all tablets. To complete the process, a stream of hot air is directed onto the tablet bed, with the exhaust temperature ranging between 60°C and 80°C, enhancing overall performance.

The advanced control panel offers precise control over various settings, including temperature and rotation speeds, allowing for tailored adjustments to meet specific research needs. When introducing tablets or granules into the pan or retrieving them, a scoop should be used. The optimal parameters for coating should be determined through experimentation and trials, ensuring the highest quality results in pharmaceutical research and development.
