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 an elegant exterior fabricated of SS 304 box with a coating pan supported in a tangential position of 35° to 45°. Coating small batches of the tablets and granules.

REQUIREMENT

The research and development department of pharmaceutical companies had to manufacture unnecessary quantities of test drugs due to existing standards coating facilities, resulting in huge wastage of effort and money.

SOLUTION

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

OPERATION

The R & D Tablet Coater is an integrated and semi-automatic unit consisting of a 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 settings, including the temperature and rotation speeds, can be measured and adjusted accurately using the advanced control panel. Feeding and retrieving the tablets/granules from the pan should be done with a scoop, and the various parameters for coating should be established through trials.

FEATURES

The R & D tablet coating machine has the exterior appearance of an elegant fabricated box with a 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.

    1. COATING PAN

The coating pan has been made from pure SS 304/SS 316 quality material, it consists of a central cylindrical portion. Opening the front side is 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

    2. HEATER

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

    3. EXHAUST PIPE

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

    4. AIR FILTER & CONTROLLER

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

    5. CONTROL PANEL

The advanced control panel offers complete control over the various setting for the coater.

    6. 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

    7. PERISTALTIC PUMP

A peristaltic pump delivers the 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.

In-Depth Guide to Ball Mill Machine, Tablet Coater, & Double Cone Blender in Manufacturing

The modern manufacturing industry relies heavily on advanced machinery to streamline production processes and ensure the highest quality output. Among the key players in this landscape are the Ball Mill Machine, Tablet Coater, and Double Cone Blender. In this comprehensive guide, we will delve deep into these three pivotal pieces of equipment, exploring their working principles, applications, and advantages in the world of manufacturing.   1. Ball Mill Machine 1.1 Working Principle The  Ball Mill Machine  is a versatile workhorse in various industries, including pharmaceuticals, chemicals, and mining. At its core, the ball mill operates on a fundamental principle – that of impact and attrition. A cylindrical shell, mounted horizontally, houses the material to be ground along with the grinding medium, typically steel balls. As the shell rotates, the balls cascade within, impacting and grinding the material, ultimately reducing it to a fine powder.   1.2 Applications P...
