Product Description
An
octagonal blender (also called an
octagonal powder blender) is a
specialized industrial mixer commonly used for
dry powders and granules in the pharmaceutical, food, chemical, cosmetics, and related industries. Heres what sets it apart:
Shape & Motion
Its eightsided (octagonal) shell creates a unique tumbling motion that gently moves materials from side to side, improving mixing uniformity at low rotational speeds
Gentle Mixing for Fragile Materials
Designed for coarse or brittle granules, it minimizes shear forcesideal for formulations needing granule integrity or uniform lubrication .
cGMP & Hygienic Construction
Typically built with SS316 contact surfaces, SS304 external parts, mirror-polished interiors, food-grade gaskets, and butterfly-discharge valvesall for cleanability and containment
Capacity Versatility
Available in capacities from small lab-scale (~130L) to large production-scale (hundreds to thousands of liters); some manufacturers offer sizes up to 10,00020,000L
Efficient Mixing
Lower power usage compared to V or doublecone blenders, while still delivering uniform blending in 1030 minutes, thanks to enhanced angular momentum from its shape
Dust-Free Handling
Many units support bin or vacuum charging, pneumatic valves, and sealed lids, maintaining environmental control and avoiding contamination
Easy Cleaning & Maintenance
Designed with hatches or manways for CIP/SIP, removable baffles, and safety interlocks, aligning with cGMP standards
Common Applications
-
Pharmaceutical: Blending active ingredients, granules, excipients, and coatings.
-
Food & Cosmetic: Mixing spices, powders, talcs, pigments.
-
Chemicals / Minerals: Uniform dispersion of solids or dry additives.
