Laboratory Double Cone Blender

Description

Laboratory Double Cone Blender is a small-scale mixing device designed for uniform blending of dry powders, granules, and crystalline materials in R&D settings, primarily for pharmaceutical, food, chemical, and cosmetic applications. Its double-cone shape—two conical ends joined by a cylindrical section—facilitates gentle, low-shear tumbling motion for homogeneous mixing without degrading fragile materials.

Working Principle of Laboratory 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.

Advantages of Laboratory Double Cone Blender

Simple, cost-effective design, easy to clean, and low maintenance.

Ideal for straightforward blending tasks but less efficient than octagonal blenders for complex or sensitive blends due to fewer mixing planes.

Key Components of Laboratory Double Cone Blender

Design and Construction: Made of stainless steel for durability, hygiene, and cGMP compliance. Features a polished interior, charging port, bottom discharge valve, and optional baffles for enhanced mixing. Safety guards and quick-release mechanisms ensure ease of use and cleaning.

Capacity: Typically ranges from 1–50 kg or 2–100 liters, ideal for lab-scale or pilot batches. Optimal fill level is 50–60% of volume for effective mixing.

Power and Controls: Powered by a 0.5–2 HP motor with variable frequency drive (VFD) for adjustable speed, digital timer, and RPM display for precise control. Low-speed rotation minimizes heat and particle breakdown.

Operation: Materials tumble via gravity-driven flow, ensuring uniform blending of free-flowing solids, even with varying densities or particle size. Discharge occurs through the bottom valve, often with dust-free options.

FAQ for Laboratory Double Cone Blender

What is a Laboratory Double Cone Blender?

The Laboratory Double Cone Blender is a compact, small-scale mixing machine designed for uniform blending of dry powders, granules, and crystalline materials in R&D labs. It features a double-cone vessel (two conical ends joined by a cylindrical section) that provides gentle, low-shear tumbling action. It is ideal for pharmaceutical, nutraceutical, Ayurvedic, herbal, cosmetic, and chemical industries for pilot batches and formulation development.

What are the key features of the Laboratory Double Cone Blender?

Key features include:

Compact cantilever design with interchangeable cones for different capacities.
All contact parts made of SS 316 with mirror polish (inside & outside).
Safety guards, butterfly discharge valve, and easy charging/cleaning ports.
VFD control panel with start/stop/inch buttons.
Worm reduction gear for smooth operation and low maintenance.

What is the working principle of the Laboratory Double Cone Blender?

It works on the principle of free-fall tumbling. The double-cone vessel rotates on a horizontal axis, causing materials to cascade and intermix through axial and radial movement. Materials are loaded (typically 50-70% capacity), tumbled for 5-15 minutes, and discharged via the butterfly valve. This gentle action ensures homogeneous mixing without generating heat or damaging fragile particles.
