Equipment Used In Pharmaceutical Industry

Pharma Equipment

Many students, freshers & qualified persons who have never visited any pharmaceutical industry are not aware of the equipment which are practically used in pharmaceutical industries for tablet manufacturing starting from granulation to packaging.

In this article, we will discuss the most commonly used equipment with their brief description for easy understanding for all who want to know about the list of equipment used in tablet manufacturing.

We will divide equipment according to their area of usage like the following,

  • Granulation
  • Compression
  • Coating
  • Blistering
  • Packaging

Equipment Used For Granulation

As we know there are two types of granulation, The first one is wet granulation & 2nd is dry granulation, so first of all, we will discuss the list of equipment for wet granulation.

Pharma Equipment

Wet Granulation Equipment

The most commonly used equipment for wet Granulation is given below,

  • Sifter
  • Granulating Equipment
  • Drying Equipment
  • Screening Equipment
  • Blending Equipment


Sifters are used for sifting or sieving & commonly used sifter in wet granulation is a Russell sifter or vibro sifter.

Russel Sifter

Russell sifter has a reservoir tank, vacuum suction delivery system, sieving chamber & vibratory system.

Granulating Equipment

For Kneading, wetting, or wet granulation various types of mixers or granulators are used. The most commonly used are as given below


RMG is a rapid-mixing granulator that is generally used for the Kneading & pre-mixing process. It has impeller & chopper blades for mixing & cutting.

Spiral Mixer

Spiral Mixer is a low-shear mixer also known as a sigma mixer where sigma shape blades are used for mixing & wetting products.

Other Mixers

Some other mixers like the diosana mixer, plough mixer, and dough mixer are also used for pre-mixing & kneading.

Drying Equipment

As we know dryers are used to remove excessive moisture during wet granulation & The following 2 types of dryers are commonly used.

  • Tray Dryer
  • FBD

Tray Dryer

Tray dryers are like big ovens where the product is placed in various trays & are dried by hot circulating air.

FBD is a fluid bed dryer where the product is dried by the fluidization process.

Screening Equipment

Screening or sieving equipment is used to reduce the particle size of granules after drying & to get uniform size granules.

The following are the most commonly used equipment for this process

  • Oscillating Granulator
  • Co Mill

Oscillating Granulator

It has a rotating arm known as a rotor & sieve is attached at the lower part of the sieving chamber. Product is added from top & reduced size product is collected from the lower side.

Co Mill

It is high-speed milling equipment used to screen the dried grains.

Blending Equipment

For final mixing or blending following mixing or blending equipment is used,

  • Double Cone mixer
  • Bin Blender
  • Twin Shell blender

Dry Granulation Equipment

In dry granulation, for sifting & mixing the same equipment is used as in the case of wet granulation. We know that in dry granulation the pressure is applied over powders to form granules & there is no wetting & drying stage in dry granulation so no wetting & drying equipment is used.

For pressure application, the following may be used.

  • Compression Machine for Slugging
  • Roller Compactor 

Direct Compression Equipment

In direct compression, no complex steps are involved so the following equipment is used,

  • Vibro Sifter
  • Bin blender or Double Cone Blender

Name Of Equipment For Compression 

When granules are prepared or powders are mixed the next step is to compress them to form tablets.

The following equipment is used during the tablet compression process.

  • Compression Machine
  • Deduster
  • Metal Detector

Compression Machine

Compression machines are used to compress granules or powder to form tablets using punches & dies which are installed on a rotating table.

Read Details Of Tablet Compression


When tablets are compressed & ejected they also have a fine powder along them & to remove it a deduster is used.

Metal Detector

All the tablets after compression are passed through the mental detector to remove any metal-contaminated tablets.

Name Of Equipment For Tablet Coating

Tablet coating is the process in which we deposit a layer of polymer over the moving bed of tablets.

The following equipment is used during the tablet coating process

  • Tablet Coater
  • Peristaltic pump
  • Mixing Tank

Tablet Coater Perforated Coating pans are used for tablet coating where spray guns are installed in the pan to deliver the automized coating suspension over tablets.

Peristaltic pump

The peristaltic pump supplies the coating suspension to the coating guns.

Mixing Tank

A mixing tank is used to prepare the tablet coating suspension.

Equipment Used For Tablet Blistering

After tablet coating the next process is to blister the tablets for which blister machines are used.

Blister Machines

Blister machines are used to pack tablets in alu alu or ALU PVC foils. Many advanced types of blister machines are used where pockets are formed & after tablet filling these pockets are sealed, embossed with Batch number & cut into individual blisters.

Packaging Equipment

The packaging is the process where blisters, bottles, sachets, etc. are packed into individual unit cartons also known as secondary Packaging.

Packaging Machines

Process of Packaging in pharma industries is a manual activity but some well-established pharma companies use cartonating machines as well.

Cartoning Machines

The cartoning machine is used to automatically insert a blister into the unit pack & all the activities like opening of unit pack, insertion of a blister, leaflet, etc., the closing of unit pack, and stamping are done by the cartoning machine.
