Ribbon Blender

The Ribbon Blender is designed for efficient mixing of pharmaceutical powders, dried granules, excipients, and other suitable bulk solid materials. It operates using a horizontal mixing trough fitted with a rotating shaft and specially designed helical ribbons. The inner and outer ribbons move material in opposing axial directions while also creating radial movement, promoting continuous circulation and ingredient distribution throughout the mixing chamber.

Intence Engineering offers Ribbon Blenders as part of its pharmaceutical blending equipment portfolio. The equipment supports dry powder mixing, granule blending, and suitable powder conditioning applications. Unlike conventional tumble blenders, the Ribbon Blender uses an internally driven agitator within a stationary vessel to move material through the mixing zone. Appropriate mixing parameters and equipment configurations are selected according to batch size, bulk density, flow characteristics, and formulation requirements.

Applications of Ribbon Blender

1. Pharmaceutical Powder Blending: Mixing suitable active ingredients, excipients, and dry formulation powders to support the required ingredient distribution before downstream manufacturing.
2. Dry Granule Blending: Blending previously dried and sized pharmaceutical granules with compatible formulation ingredients for subsequent processing operations.
3. Powder and Additive Incorporation: Distributing suitable minor ingredients, processing aids, and additives within bulk powder formulations under controlled mixing conditions.
4. Pharmaceutical and Allied Processing: Supporting compatible dry powder and granular mixing applications in pharmaceutical, nutraceutical, food, chemical, and allied manufacturing.

Key Features

• Horizontal Mixing Chamber: Uses a stationary horizontal trough to accommodate powder and granule blending during batch processing.
• Helical Ribbon Agitator: Ribbon blending technology employs inner and outer helical mixing elements mounted on a horizontal rotating shaft.
• Counter-Current Mixing Action: Opposing ribbon pitches promote material movement in different axial directions to support thorough mixing.
• Axial and Radial Material Movement: Continuous circulation moves ingredients along the vessel and across the mixing chamber.
• Efficient Dry Powder Mixing: Suitable for blending compatible powders, dried granules, and formulation ingredients.
• Mechanically Driven Agitation: Uses internal ribbon movement to mix materials without requiring rotation of the entire blending vessel.
• Batch Processing Capability: Supports mixing of individual batches according to the required production workflow.
• Flexible Material Processing: Suitable mixing arrangements can be selected based on powder flow, bulk density, and blending requirements.
• Downstream Process Integration: Supports preparation of suitable materials for subsequent conveying, sifting, filling, and other manufacturing operations.

Available Capacity

Blender Equipment Range: 1 L to 10,000 L or Higher

Intence Engineering’s documented blending equipment portfolio covers capacities from 1 L to 10,000 L or higher, depending on equipment type and customer requirements. This range applies to the broader blending portfolio and is not confirmed as the capacity range of the Ribbon Blender alone. Appropriate Ribbon Blender capacity depends on the gross vessel volume, working fill level, material bulk density, agitator configuration, and required batch quantity. Specific model capacities and operating parameters should be confirmed with Intence Engineering.
