Overview
The Octagonal Blender Machine is a tumble blender designed for low-shear, uniform mixing of dry powders and granules. Available in laboratory and production scales with cGMP-compliant configurations for pharmaceutical, nutraceutical and food industries. Product-contact surfaces are stainless steel SS316 / SS316L; non-contact structures typically SS304 or mild steel cladded with SS304.

Key features

• Capacity range: laboratory units up to 5000 kg industrial batches.
• SS316 / SS316L product-contact construction for hygiene and cleanability.
• VFD speed control, jog mode and digital timer options.
• Safety features: interlocks, safety railing and emergency stop.
• Options: PLC/HMI automation, recipe control, vacuum/dust-tight charging and custom discharge valves.
• Designed for gentle tumbling to protect fragile or heat-sensitive powders.

Model variants (typical)

• Laboratory scale octagonal blender: compact R&D model; batch capacities 2 kg, 5 kg, 10 kg; gross volumes 6 L, 15 L, 30 L.
• 100 kg model: GMP production model, gross volume ~300 L (suitable for 100 kg batch).
• 200 kg model: GMP production model, gross volume ~600 L (suitable for 200 kg batch).
• 500 kg model: GMP production model, gross volume ~1500 L (suitable for 500 kg batch).
• Production/industrial models scalable up to 5000 kg batch capacity.

Working principle
The octagonal chamber rotates about a horizontal axis causing powder to lift, cascade and intermix in multi-directional patterns. The polygonal geometry reduces dead zones and promotes uniform mixing with minimal heat generation and particle degradation. Typical blend cycles: 10–20 minutes, depending on material and fill level.

Options & customization

• Dust-free bin charging / vacuum loading systems to minimise airborne particles.
• Discharge choices: TC-ended discharge, manual butterfly valves (e.g. 6" or 10" depending on model) or automatic valves on request.
• Automation: VFD speed control, RPM indicator, timers, PLC/HMI with recipe control and data logging.
• Electrical options: standard three-phase or flameproof/ex-proof assemblies for hazardous areas.
• Validation support: DQ, IQ, OQ, PQ and FAT documentation available.

Applications
Suitable for pharmaceuticals, nutraceuticals, herbal & ayurvedic powders, food ingredients and spices, cosmetics and speciality chemicals where hygiene, repeatability and low-shear handling are required.
