Small Scale Double Cone Blender

Q: What is the capacity of the Small Scale Double Cone Blender?

The standard model (DCB-5) offers: Gross Capacity : 8 Liters Working Capacity : 4 Liters (approx.) Interchangeable cone design allows different capacities on the same base machine. Models up to 100 liters are also available for small-scale production.

Description

Small Scale Double Cone Blender is a compact, low-shear mixing device designed for uniform blending of dry powders and granules in small batches, typically ranging from 5 to 100 liters. Its distinctive double-cone shape, with two conical ends connected by a cylindrical section, facilitates efficient mixing through tumbling motion. Widely used in pharmaceuticals, food, chemicals, and cosmetics, it is ideal for R&D, pilot plants, or small production runs where precision, hygiene, and minimal material degradation are critical.

Working Principle of Small Scale Double Cone Blender

The Double Cone Blender operates on the principle of free-flow tumbling, where the vessel’s rotation causes materials to cascade and intermix. The process involves:

Loading: Powders or granules are loaded through the top port(s), typically filling 50-70% of the vessel to optimize mixing.

Mixing: The vessel rotates on its horizontal axis, creating a tumbling motion. The conical shape ensures axial and radial mixing, as materials flow from the ends to the center and back. Mixing time is 5-15 minutes, depending on material properties like particle size, density, and cohesiveness.

Discharge: The vessel is stopped, and the blended material is released through the bottom/side valve, often gravity-fed or assisted by slight tilting.

Key Components of Small Scale Double Cone Blender

Double Cone Vessel: A stainless steel (SS304/SS316) container with two conical ends, polished for GMP compliance. Capacities typically range from 5-100 liters for small-scale models.

Drive System: Electric motor with a gearbox for controlled rotation. Variable frequency drives (VFDs) allow speed adjustment.

Charging/Discharge Ports: Top port(s) for loading; bottom or side valve for discharge, often manually or pneumatically operated.

Frame/Stand: Robust mild steel or SS stand, sometimes with lockable wheels for mobility.

Control Panel: Includes start/stop, speed control, and safety interlocks.

Optional Features: Spray nozzles for liquid addition, vacuum loading, or jacketed cones for heating/cooling.

FAQ for Small Scale Double Cone Blender

What is a Small Scale Double Cone Blender and what is it used for?

The Small Scale Double Cone Blender is a compact, low-shear tumble mixer designed for uniform blending of dry powders and granules in small batches. It is ideal for R&D labs, pilot plants, and small production runs in Pharmaceutical, Ayurvedic, Herbal, Nutraceutical, Biotech, and Cosmetic industries. With capacities typically ranging from 5–100 liters, it is perfect for formulation development, scale-up studies, and small-batch manufacturing while maintaining cGMP standards.

How does the Small Scale Double Cone Blender work?

The blender operates on the principle of free-flow tumbling. The double-cone vessel rotates on a horizontal axis, causing materials to cascade and intermix gently through gravity. The conical shape promotes excellent axial and radial mixing. Materials are loaded to 50–70% of gross volume, achieving high homogeneity in just 5–15 minutes with minimal shear and heat generation.

What are the key features and advantages of the Small Scale Double Cone Blender?

Compact cantilever design with interchangeable cones
All contact parts made of SS 316 with mirror polish
Gentle low-shear mixing preserves particle integrity
Easy charging and discharge via butterfly valve
Safety guards, VFD control, and worm gear reduction
