Small Scale Octagonal Blender

A Small Scale Octagonal Blender also known as a mini, lab, or R&D octagonal blender is a compact mixing machine primarily used in pharmaceutical, chemical, food, and cosmetic industries for blending dry powders, granules, and crystalline materials. Its octagonal (eight-sided) container design promotes efficient, gentle tumbling action, ensuring uniform mixing at low speeds while minimizing shear and heat generation. This makes it ideal for sensitive or fragile products, such as delicate granules or heat-sensitive compounds. Unlike larger industrial models, small-scale versions are designed for research and development (R&D), pilot testing, or low-volume production, typically handling batches from 1-50 liters.

These blenders are often cGMP-compliant, easy to clean, and feature quick-connect mechanisms for integration with other lab equipment.

Key Features

• Design: Octagonal-shaped body with a rectangular central section and polygonal frustums at top and bottom. Includes removable baffles for enhanced mixing and a slow-speed rotation to reduce power consumption and material degradation.

• Capacity: Small models range from 1-25 liters, filling to about two-thirds capacity for optimal tumbling.

• Controls: Digital timers, speed displays, and optional PLC-based HMI for automation. Motors are usually 0.5-1 HP, single-phase.

• Materials: Stainless steel construction for corrosion resistance and hygiene.

• Advantages Over Other Blenders:

  • More space-efficient than V or double-cone blenders.

  • Lower RPM requirements due to multi-directional granule flow from eight sides.

  • Balanced operation even at higher capacities within small scale.

• Applications: Homogeneous blending of powders/granules in pharma, cosmetics, food, and chemicals.

How It Works

1. Load material into the octagonal container (up to 2/3 full).

2. Secure the blender to a drive unit via locking screws.

3. Set speed and time on the digital controls.

4. The slow rotation causes materials to cascade from all eight sides, achieving homogeneity in 5-15 minutes.

5. Unload via a discharge valve; clean in place (CIP) compatible.

Salient Features of Octagonal Mixer

• Compact GMP model.

• The octagonal shape & slow speed of rotating gives sufficient continuous movement to the granules, result in good quality.

• General structure & safety guards made out of mild steel & colored in Standard Model and made out of SS 304 & polished to the matt finish in GMP Model.

• Maximum care has been taken to ensure safe operation of the unit.

• Manual rotating facility with hand wheel for inching.

• Bigger size batch at low power consumption

• Suitable for dry mixing of products in granule form.

• Easy for loading and unloading of material.

• Easy for cleaning.

• All contact parts are made out of SS 304 / SS 316 or SS 316 L quality material, as per customer requirement.

Process Operation of Octagonal Blender Machine

The Octagonal Blender is an efficient and versatile blending machine for mixing and lubrication process of dry granules homogeneously. Two third of the volume of the Cone Blender is filled to ensure proper mixing. The Octagonal Blender Machine gives best result for granules due to very slow speed and octagonal shape of container. It is uses in application of Pharmaceutical, Food, Chemical and Cosmetic products.

In Octagonal Blender the granules come from all sides due to the octagonal shape of the product container, hence requirement of blender RPM is less. Octagonal blender design suitable mainly for Crystalline & Granular type material. This type of material gets sufficient continuous movement due to their shape if container have only slow movement and will results in good quality of blending / lubrication of granules.
