🔹 Various Types of Blenders and Their Purpose

1. Double Cone Blender (DCB)

• Purpose: Used for homogeneous mixing of dry powders and granules.

• Advantages: Gentle mixing, suitable for fragile materials, low shear force.

• Applications: Commonly used in powder mixing for tablets and capsules.

2. V-Blender (Twin-Shell Blender)

• Purpose: Provides uniform mixing through tumbling action.

• Advantages: Effective for free-flowing powders, simple design, easy cleaning.

• Applications: Used in blending active pharmaceutical ingredients (APIs) with excipients.

3. Bin Blender / IBC Blender (Intermediate Bulk Container Blender)

• Purpose: Material is blended directly in a bin (container) that doubles as storage.

• Advantages: No transfer loss, reduced cross-contamination risk, scalable.

• Applications: Widely used in large-scale production for flexible batch mixing.

4. Ribbon Blender

• Purpose: Horizontal blender with helical ribbons for continuous mixing.

• Advantages: Good for cohesive powders, wet granules, and viscous materials.

• Applications: Mixing of granules, powders, and sometimes wet mass before granulation.

5. Planetary Mixer

• Purpose: High-shear mixer used for semi-solid and viscous materials.

• Advantages: Uniform mixing of ointments, creams, gels, and dough-like materials.

• Applications: Topical formulations, wet granulation.

6. Octagonal Blender

• Purpose: Gentle mixing with less space requirement.

• Advantages: Suitable for crystalline or fragile materials, occupies less headroom.

• Applications: Blending APIs with excipients in small to medium batches.

7. High-Shear Mixer / Granulator

• Purpose: Mixing, wet granulation, and homogenization in one unit.

• Advantages: Fast, efficient, produces uniform granules.

• Applications: Tablet and capsule granulation.

8. Fluidized Bed Processor (FBP) – as a Blender

• Purpose: Fluidization ensures mixing of powders before granulation or coating.

• Advantages: Efficient mixing with drying and coating capability.

• Applications: Blending, drying, granulation, coating of powders/granules.
