Lab Scale Octagonal Blender

A Lab Scale Octagonal Blender is a compact mixing device designed for research and development (R&D) or small-batch production, primarily used in pharmaceutical, food, chemical, and cosmetic industries to achieve homogeneous blending of dry powders, granules, or crystalline materials without degrading particle structure. Its octagonal container promotes multi-directional tumbling motion at low speeds, allowing materials to cascade from all sides for efficient, gentle mixing with minimal RPM requirements—typically filling the container to about two-thirds capacity for optimal results.

Key Features and Specifications

• Design and Construction: Features an octagonal body with a rectangular central section and polygonal top/bottom frustums, often equipped with baffles for enhanced mixing efficiency. Made from stainless steel for durability, hygiene, and cGMP compliance; includes safety railings, quick-locking mechanisms for easy attachment/detachment, and dust-free operation options.

• Capacity: Lab models typically range from 5–10 kg up to 50–300 kg for pilot-scale, suitable for small batches in labs or testing.

• Power and Controls: Often powered by a 1 HP single-phase motor with AC variable frequency drive, digital speed display, timer for automated cycles, and a gearbox for high torque at low speeds.

• Operation: Slow tumbling action ensures uniform lubrication and blending, ideal for fragile or free-flowing materials like those used in tablet/capsule formulations; discharge via bottom valve.

• Advantages Over Other Blenders: Provides more uniform blends than cone blenders due to the eight-sided entry points, reducing dead zones and enabling faster, more efficient mixing for sensitive materials.

These blenders are versatile for applications like homogenizing powders irrespective of density variations and are easy to clean/maintain, often with validation support for pharmaceutical use.

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.
