LRMIX ribbon blenders and conical mixers are used across the following food powder production categories:
Choosing the Right Food Powder Mixer: Ribbon Blender vs. Double Spiral Conical Mixer
Both the horizontal ribbon blender and the double spiral conical mixer are widely used in food powder production, but they suit different materials and process requirements. The table below summarizes the key differences to help you select the correct machine:
| Criteria | Horizontal Ribbon Blender | Double Spiral Conical Mixer |
|---|---|---|
| Mixing Principle | Mechanical mixing — inner and outer helical ribbons move material axially in opposite directions | Gravity-assisted mixing — twin spiral screws orbit the conical vessel wall, lifting material upward |
| Best For | Medium to high-volume batches; cohesive, sticky or unequal density powders; powders with liquid addition | Free-flowing fine powders; fragile granules; products requiring gentle, low-shear mixing |
| Mixing Uniformity | ✓ Very high — counter-flow ribbon action ensures thorough homogenization | ✓ High — especially for free-flowing powders with similar particle sizes |
| Liquid Addition | ✓ Suitable — spray nozzles can be installed for even liquid distribution | Not recommended — better suited to dry-only blending |
| Discharge | Bottom butterfly valve — fast, complete discharge | Bottom cone outlet — gravity discharge with no residue |
| Cleaning | Good — large access cover for manual cleaning; CIP option available | Excellent — smooth conical interior, no dead zones, easy inspection |
| Typical Batch Size | 100L to 3,000L+ | 200L to 2,000L+ |
| Typical Applications | Seasoning blends, baking premixes, protein powders, feed premixes | Fine spices, pharmaceutical-grade powders, fragile granules, nutraceuticals |
LRMIX Food Powder Mixing Equipment
Both machines are available with SS304 food-contact surfaces, polished interior finish and sanitary discharge valves as standard for food industry applications:
Horizontal Ribbon Blender
The horizontal ribbon blender is the most widely used dry powder mixer in the food industry. The U-shaped trough contains a central shaft fitted with inner and outer helical ribbon blades that rotate in opposite directions — moving material toward the center and outward simultaneously. This counter-flow action produces fast, highly uniform blending of dry powders, granules and powder-liquid combinations. Mixing cycle typically 3–15 minutes depending on material and batch size.
- SS304 trough, shaft and ribbon — food-grade standard
- Inner and outer counter-rotating ribbon design
- Butterfly valve bottom discharge — complete evacuation
- Liquid spray nozzle option for coating and wetting
- Heating/cooling jacket available
- Capacities from 100L to 3,000L per batch
- Full cover with safety interlock
Double Spiral Conical Mixer
The double spiral conical mixer (also known as a nauta mixer or conical screw blender) uses two spiral screw agitators that orbit the inner wall of a conical vessel while rotating on their own axis, continuously lifting material from the bottom to the top of the cone. This gentle, low-shear mixing action is ideal for fragile food granules, fine powders and hygroscopic ingredients that could be damaged or degraded by high-shear mixing equipment.
- SS304 conical vessel — food-grade, polished interior
- Twin spiral screws — gentle, low-shear mixing action
- No dead zones — full conical interior coverage
- Gravity discharge — complete emptying, easy cleaning
- Suitable for fragile granules and fine powders
- Capacities from 200L to 2,000L per batch
- Dust-tight cover with inspection port
