Fluid bed technology is an innovative solution for various industries, such as pharmaceuticals, nutraceuticals, foods, chemicals, and agrochemicals. It offers a versatile solution for processes like granulation, drying, and coating. At anish pharma, we are committed to excellence and provide comprehensive solutions that meet the evolving needs of our clients. Our fluid bed processors are designed with a focus on scalability and incorporating Industry 4.0 standards. They deliver optimal efficiency, high outputs, and batch-to-batch uniformity throughout the product lifecycle.

Fluid bed processors use different techniques, determined by the position of the spray nozzle, to suspend particles in the air. This process is based on the fundamental principle of fluidisation. It facilitates various operations such as drying, top spray granulation, pellet coating, powder layering, and hot melt coating, each with unique advantages and applications that cater to the diverse requirements of different industries. As we delve deeper into the intricacies of fluid bed technology, it becomes evident that anish pharma’s solutions are poised to revolutionise manufacturing processes. Our solutions drive innovation and help businesses succeed in today’s dynamic landscape.

Fluid bed processors operate through various techniques depending on the positioning of the spray nozzle, namely:

  1. Drying
  2. Granulation/Agglomeration by Top Spray
  3. Pelletising by Bottom Spray
  4. Pelletising by Tangential Rotor Loader
  5. Coating by Bottom Spray
  6. Hot Melt Coating

At its core, fluidisation is the principle behind fluid bed technology. This process involves passing gas or air at a velocity greater than that of the particles or solids, suspending them in the air and causing them to move upwards. This suspension of particles facilitates various operations.

Let’s delve deeper into each process of fluid bed technology:


When particles are initially wet, they undergo fluid bed drying, a process where the moisture within them is effectively removed, resulting in particles with significantly reduced moisture content. This method is crucial for ensuring product stability and shelf-life. By meticulously adjusting parameters such as the inlet temperature, blower speed, and bed height, we can precisely control the drying process, optimising heat exchange and drying time to achieve the desired outcome.

Granulation/Agglomeration by Top Spray:

Top spray granulation is a method where a liquid binder is sprayed onto powders or a mixture of active ingredients and excipients while they are fluidised. This results in the formation of granules with unique characteristics, such as low bulk density and high porosity. These granules are particularly advantageous for products requiring enhanced solubility and flowability, making them ideal for various pharmaceutical and industrial applications.

Pelletising by Bottom Spray:

During pelletising by bottom spray, layers of powdered drugs from drug solutions, along with excipients, are precisely sprayed over starter seeds using a bottom spray nozzle. This process ensures the uniform deposition of layers, facilitating the thorough mixing of drugs and excipients. The outcome is the production of smooth pellets with excellent sphericity, which is essential for applications demanding precise dosage delivery and uniform distribution of active ingredients.

Pelletising by Tangential Rotor Loader:

In contrast to bottom spray coating, pelletising by tangential rotor loader introduces a unique approach. The spray nozzle is inserted tangentially into the product bed, creating a circular motion through a motor-driven rotating disc. This innovative technique allows for faster dry powder loading and simultaneous semi-drying. It is particularly well-suited for applications requiring high loading on starter seeds and for producing Multiple Unit Pellet System (MUPS) formulations.

Coating by Bottom Spray:

Coating by bottom spray technology is employed for uniform coating, vital for applications such as barrier coating and extended-release formulations. This process harnesses the energy of fluidisation to uniformly coat particles or pellets, ensuring consistent thickness and reproducible drug release patterns. The result is a precisely coated product with enhanced performance and efficacy.

Hot Melt Coating:

Hot melt coating involves spraying a hot molten coating material onto particles or pellets to create a hydrophobic layer. This innovative method is utilised to achieve sustained release of specific chemicals or food preservatives, enhancing product stability and efficacy. Hot melt coating offers a versatile solution for various pharmaceutical and industrial applications, enabling precise control over release kinetics and product performance.
