Precision Blending Technologies for Powders and Granules
Achieving a perfect blend is the critical first step in assuring product quality, whether it is a uniform spice mix for MTR or a precise chemical formulation. Ven-Tech Systems offers a range of industrial mixers engineered to handle materials with varying bulk densities, particle sizes, and flow characteristics.
Double Helical Ribbon Blenders for High-Speed Mixing
The Ribbon Blender is the workhorse of the dry powder processing industry. Ven-Tech’s design features a U-shaped horizontal trough with a specially engineered double helical agitator.
Working Principle:
The agitator consists of two ribbons: an outer ribbon that moves material toward the centre discharge and an inner ribbon that pushes material toward the ends. This counter-current action creates a vigorous mixing environment, generating a fluidized bed that ensures rapid and homogenous blending, typically within 15 to 20 minutes.
Key Engineering Features:
- Dead-Zone Elimination: We maintain a precision clearance (3-5mm) between the ribbon tip and the trough shell to prevent material stagnation, ensuring that every gram of product is part of the mix.
- Heavy-Duty Drive: Equipped with high-torque gearboxes to handle high-viscosity loads or sudden start-ups under load.
- Shaft Sealing: We utilize air-purge stuffing boxes or mechanical seals to prevent fine powders from leaking into the bearings or the environment.
Applications:
- Spice Industry: Mixing turmeric, chilli, and coriander powders with oil/oleoresins.
- Bakery: Pre-mixing flour with minor ingredients like baking soda and flavours.
- Chemicals: Blending dry detergent powders and additives.
For fragile materials where particle degradation must be avoided, the Ven-Tech Double Cone Blender is the ideal solution. Unlike ribbon blenders that use mechanical shear, cone blenders rely on gravity to tumble the material as the vessel rotates.
Benefits:
- Gentle Handling: Ideal for mixing fragile pharmaceutical granules or crystals without breaking them.
- Total Discharge: The conical shape allows for 100% gravity discharge, leaving no residue—critical for batch-to-batch cross-contamination prevention in pharma.14
- Easy Cleaning: The interior is mirror-polished and free of internal baffles or shafts, making CIP (Clean-In-Place) procedures fast and verifiable.
