Introduction – Fluid Bed Dryer Granulator

Main components:

• Drying Chamber:
  This is the main part where the fluid bed process occurs. The chamber is usually made of stainless steel, ensuring heat resistance and corrosion protection. It includes a mesh or perforated plate that supports the product and allows hot air to pass through.

• Blower System:
  Generates high-pressure airflow to keep the material in a fluidized state. The blower is equipped with filters to ensure clean air enters the drying chamber.

• Heater:
  Usually consists of electric heaters or gas burners to heat the air before it enters the chamber.

• Spray System:
  Used to spray binder solutions or other liquids onto the powder particles, aiding in granulation. Depending on the design, top-spray or bottom-spray nozzles can be used.

• Exhaust Air Filter:
  Removes dust and fine particles before releasing air into the environment, ensuring compliance with environmental standards.

• Control Panel:
  Allows operators to monitor and control process parameters such as temperature, airflow, spray rate, and drying time.

• Product Discharge:
  The outlet where the dried or granulated product is collected after processing.

Working Principle:

• Fluidization:
  Hot air is blown through the product bed, creating a “fluidized” state where particles behave like a fluid.

• Drying:
  The hot air evaporates moisture from the material, reducing the moisture content to the desired level.

• Granulation:
  Binder solution is sprayed during fluidization, causing powder particles to agglomerate and form uniform granules.

Applications of Fluid Bed Dryer Granulator:

• Pharmaceutical Industry:

  • Granulating powders for tablet or capsule production.

  • Drying granules or pharmaceutical raw materials to the required moisture level.

  • Coating tablets or granules for protection or controlled drug release.

• Food Industry:

  • Drying food powders, grains, and spices.

  • Granulating products such as milk powder, nutritional powders, and functional food granules.

• Chemical & Cosmetic Industry:

  • Drying and granulating powdered chemicals such as base powders and fillers.

🌟 Introduction to High shear mixer granulator TCT-200

The High shear mixer granulator TCT-200 is a critical piece of equipment in the pharmaceutical industry, primarily used for mixing and wet granulation during the production of solid dosage forms such as tablets.

Its key functions and applications include:

1. 🧪 Homogeneous Mixing

The mixer ensures thorough blending of all formulation components—including active pharmaceutical ingredients (APIs), excipients, and other additives—achieving uniformity in both physical properties and product quality.

2. 💧 Wet Granulation

In tablet production, the high shear mixer transforms powder blends into uniform wet granules by introducing a binder solution. These granules improve flowability and compressibility, enabling efficient tablet compression.

3. ⚡ Shortened Mixing Time

Thanks to its high-speed mixing and cutting mechanisms, processing time is significantly reduced compared to conventional methods, resulting in increased production throughput.

4. 🧭 Granule Quality Control

The combined cutting and mixing action allows precise control over granule size and shape, ensuring tablet properties such as dissolution, hardness, and other critical quality attributes meet industry standards.

5. 🌍 Versatile Applications

Beyond pharmaceuticals, high shear mixers are widely used in the food, cosmetic, and chemical industries to produce products with consistent structure and stable quality.

Film coater FSC-200JP manufactured by T&T MACHINERY applies advanced film-coating technology to protect tablets, enhance product quality, improve aesthetics, and increase production efficiency.

Introduction to Film coater FSC-200JP

A film coating machine is pharmaceutical equipment used to apply a thin film layer onto the surface of tablets. This coating layer helps protect the active ingredients, control the drug release rate, mask unpleasant tastes or odors, and improve the overall appearance of the product.

Main Components:

1. Coating Drum

• The chamber that holds and rotates the tablets during the coating process.

• Can be perforated or non-perforated to control airflow.

• Adjustable rotation speed ensures even movement of the tablets.

2. Spray System

• Consists of a pump, spray gun, and nozzle.

• Sprays the coating solution evenly onto the tablets.

• Can use either pressure spray or pneumatic spray technology.

3. Air Handling System

• Includes hot air blower, heater, and air filters.

• Dries the coating layer after spraying to form a uniform thin film.

• Some machines feature humidity control systems.

4. Exhaust System

• Removes solvent vapor and dust during the coating process.

• Ensures a clean and safe working environment.

5. Control Panel

• Equipped with a PLC touch screen or push buttons.

• Allows adjustment of temperature, drum rotation speed, and spray rate.

Applications of Automatic Film Coating Machine:

✅ Tablet Film Coating

• Applies a polymer film layer to protect the active ingredients.

• Controls the drug release rate (e.g., enteric coating, controlled release coating).

• Masks unpleasant taste and improves patient compliance.

✅ Enteric and Gastric-Resistant Coating

• Prevents the tablet from dissolving in the stomach, only releasing in the intestine.

• Suitable for acid-sensitive drugs such as anti-ulcer medications and digestive enzymes.

The Multi mill SH-200 manufactured by T&T MACHINERY is commonly known in the pharmaceutical industry as a granule sizing or re-granulating machine.
It is typically used in the wet or dry granulation process to:

• Adjust and standardize granule size after uneven granulation.

• Smooth and homogenize granules for more stable tablet compression.

• Separate oversized or undersized granules and bring them back to the desired size (by using sieves with different mesh sizes).

🔧 1. Machine Structure:

Depending on the model, the most common design is the oscillating granulator type. Main components include:

• Feeding hopper: Where the non-standard granules are loaded.

• Oscillating blade system: The blade moves back and forth (or rotates) to cut and push granules through the sieve.

• Sieve (screen): A stainless-steel mesh plate with specific mesh sizes for classifying granules.

• Drive motor: Powers the blade and moving parts.

• Discharge outlet: Where standardized granules are collected.

• Machine frame and housing: Usually made of stainless steel (SS304 or SS316), meeting GMP standards.

⚙️ 2. Working Principle:

• Wet or dry granules are fed into the hopper.

• The oscillating (or rotating) blade pushes the material through the sieve.

• Granules are cut, broken down, and filtered to the desired size.

• Standardized granules are collected at the discharge outlet, while oversized granules are reprocessed or discarded.

🧪 3. Applications in the Pharmaceutical Industry:

• Sizing granules after wet granulation to ensure uniformity before drying.

• Resizing dried granules to reduce size and prevent agglomeration.

• Preparing granules for tablet compression — resulting in consistent, durable, and visually uniform tablets.

• Also applied in functional food, cosmetics, chemical, and food industries (e.g., instant tea granules, nutritional powder).
