Various Types of Blenders and Their Purpose

🔹 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.
