Fluid Bed Coating Machine - Description

Detailed Information About Wurster Coating Machine

SHREE BHAGWATI Multifunctional Fluidized Bed (also known as Wurster Coating Machine, Fluid Bed Coating Machine, Fluidized Bed Coater) is most helpful to apex industries such as food industry, chemical industry, pharmaceutical industry and various other industries to combine the process of bottom spray coating and tangent spray pelleting, top spray granulating, coating, drying, etc. into a single unit.

Wurster Coating machine

This single equipment production process is one of the best pelletization techniques. Most of the fluid techniques are known for high rates of heat and transfer techniques. Core penetration for even highly soluble material is possible with this water-based technique. Diverting the particles around the nozzle which releases the spray allows a faster frequency of the spray to be distributed or coated and also lowers the processing time. This machine is aimed to develop such an innovation that develops sustained-release formulations and to scale up the traditional or conventional method of coating particles. It is useful for the following processes or where such process is required:-

  • Controlled release coatings
  • A fine coating of particles
  • Aqua or solvent-based solutions
  • Active layering

Wurster Fluid bed Coating machine

To simplify the meaning of Wurster coating, it is the encapsulation of discrete particles in a fluidized bed using differential airflow to create a cyclic movement of material. There is a nozzle at the bottom of the fluidized bed from which the differential air flows up and coats it with an atomized material to form a core strong structure. This process involves the coating of individual particles till the desired number of layers are formed on the core shell-like structure. Scientific research proves that this liquid coating can provide the finest of coatings and with uniformity which reduces the need for a lot of coats and also reduces cost. The best part of this fluid bed coating process is that it can coat the tiniest of crystals or capsules. This perfection is very useful in the manufacturing process creating optimal and high quality for an end to end-users.

After the Wurster coating is done, they move out to a compartment where another layer of coating can be applied. The input is processed in a manner to avoid agglomeration. The advantages of using this machine are:

  • It ensures high mixing precision, shorter batch times, easy cleaning, and no residue in the form of discharge.
  • Different batch size capacity as per the model desired
  • Granulation system and technique using PLC control and MMI touch screens
  • High peristaltic pressure pump for accurate flow
  • It is a single-piece device with easy to detach and clean parts
  • Explosion flap to prevent any damage

This Fluidised bed coater allows the spray coating on small particles and the product property or requirement can be enhanced depending on the suitability and need. This encapsulating acts like a protective layer and is very helpful in increasing the shelf life of any product that is coated. The durability increase helps in the product being supplied globally without the fear of being altered. Another wonderful use of wurster coater is that some products may release odours or release certain chemicals on being exposed. This coating helps in curbing that and acts as a major protection substance.

This Fluid bed coater has universal applications and for expanding production capacity in many industries. In an industry where drug delivery plays a major role the era of advancement in such a field is very appreciable. These methods have gained much popularity due to their unique benefits, enhanced drug benefits, and uniform packing, and standardized products. The Wurster fluidization is named after its inventor Mr. Dale. E Wurster Ph.D. (1976) had immense knowledge of the formulation process. This process is sure to guarantee cost optimization, efficient manufacturing processes, and utmost satisfaction to its clients. This modified and homogenous system not only provides homogeneity to the product but also a boon to mankind in disguise.

Additional Features Of Wurster Coater

There are additional features that our Wurster coating machine has to offer. Additional features like the explosion flap present in the machine make sure the person or the worker who is coordinating with the machine is safe, and on the other hand, the machine doesn’t create an explosion or damage. Our fluid bed coater provides a convenient user interface, which is preferred for numerous industries. The fluidized bed coater also has a blower that instantly stops whenever air pressure present in the filter bag of the locking gasket faces any downfall, which is below the required set value of the Wurster coater.


Detailed Process Description & Features of Fluid Bed Coater Wurster Coater


Wurster Coating Machine (Fluid Bed Coating Machine, Fluidized Bed Coater) uses special airflow (radial, tangential and horizontal) to make the perfect mixing of the dissolvable products such as granules, pellets, extrudates and powder. These products are mixed in the unit of jinggong fluid bed.

All the fluidizable products.

Binder spraying on pulverized products can produce all kinds of requested granules.


  • WIP online cleaning system and Dehumidification system are optional.
  • Under the control of HMI and PLC, it can print and record operation parameters.
  • It can set many parameter groups and is easy to operate.
  • Within 60-120 minutes, spray granulating can be accomplished due to its high efficiency.
  • Our WURSTER Coating System allows pellet contact only with the atomizing area to maintain uniformity of coating and improvement in speed.
  • This Coating System uses heated air and centrifugal rotary disc technology for the tangent spray to produce pellets directly from the power.
  • All the three functions are performed in the closed unit to prevent dust pollution in the workshop.
  • The WURSTER System is made of stainless steel SS316 and SS314 as they do not react with the material chemically.
  • 2bar, 10bar, 12bar and anti-explosion categories can be selected to ensure safety.
