INTRODUCTION

• TABLET PRESS

A tablet press is a mechanical device that

compresses powder into tablets of uniform size and

weight. A press can be used to manufacture tablets of a wide variety of materials,

including pharmaceuticals, illicit drugs such

as MDMA and cosmetics. To form a tablet, the

granulated material must be metered into a cavityformed by two punches and a die, and then the

punches must be pressed together with great force to

fuse the material together.



There are 2 types of tablet presses:

• 1. Single-punch• 2. Rotary tablet pressesMost high speed tablet presses take the form of a rotating

turret that holds any number of punches. As they rotate

around the turret, the punches come into contact with camswhich control the punch's vertical position. Punches anddies are usually custom made for each application, and canbe made in a wide variety of sizes, shapes, and can becustomized with manufacturer codes and scoring lines tomake tablets easier to break. Depending on tablet size,shape, material, and press configuration, a typical modernpress can produce from 250,000 to over 1,000,000 tabletsan hour.

COATING PAN• There are many ways to coat tablets. Sugar coating• was one of the earliest methods, and the process is still

• widely used in the confectionery industry. Wurstercoating is another means. It employs a cylindricalchamber

• in which tablets are suspended by air and a coatingsolution is introduced into the air stream. Fluid-bed

coating• is a similar process. Dry coating is the technique of

making a tablet within a tablet. But the principle meansof

• applying a coating to pharmaceutical and nutraceutical

1. Hi-Coater• "Stretched" Tablet Coating Design Provides ShorterProcess Times

• The most effective method to increase spray rates for

any tablet coating process is to increase the numberof spray guns within the coating pan. An increasedspray zone is accomplished by lengthening thecoating pan while maintaining the same diameter.The “Stretched” coating pan can incorporate as many

as ten spray guns – doubling the amount of spray guns in a typical batch coating system. The“Stretched” design also minimizes tablet attrition by reducing the tablet bed depth when compared to a

similar batch size in a larger pan diameter.



Manifold Spray Bar Provides Cleaning

Advantages

• Freund- Vector’s manifold spray bar eliminatesthe external nozzle air and solution lines on theexterior of the spray bar. Instead, nozzle air and

solution is delivered within the interior of thespray bar. Freund- Vector’s one-gasket designallows for quick assembly of the spray bar.Changing the number of spray guns has never been easier.



• Cleanable Design• For fully perforated pans, the pan cabinet is fully

welded. This allows the lower cabinet to be filled with water, allowing the bottom of the pan tosoak and rotate in cleaning solution. Further, thiseliminates seals and/or gaskets around the

cabinet that require additional cleaning orinspection.

• Anti-Marking Pans• Every coating pan is manufactured with a high-

buff mirror polish, anti-slide baffles and slottedperforations. Slotted perforations have beenproven to reduce tablet attrition when comparedto standard round perforations.



2.Perforated Coating Pan • FEATURES:• The control system of the coating pan consists of PLC and HMI. Touch

screen 10" Simatic Siemens panel view. The design is ergonomic andprogramming is easy and flexible.

• The coating system peristaltic pump, WM type, with constant pressuredelivers a constant rate. The quantity of sprayed coating suspension is balanced automatically, thereby stabilizing the effect of atomization,preventing the spray gun from clogging.
