Ribbon Mixers

Davis Ribbon Mixers are equipped with a double ribbon agitator will mix hog and poultry feed in only three minutes. They are available with several options to suit your specific application including scales, gear drive systems, liquid fat handling systems and various legs and outlet options.

Ribbon mixers are industry-leading batch mixers engineered for rapid, homogenous blending of powders, granules, and semi-dry pastes. Featuring a counter‑flow double helix ribbon mounted on a horizontal trough, these mixers provide consistent, low-shear mixing that preserves particle integrity while ensuring tight blend uniformity.

Quick FAQ:

Q: Are ribbon mixers suitable for fragile materials? A: Yes — their low-shear action gently blends delicate particles with minimal breakage. Q: How long does a typical batch take? A: Many mixes reach target uniformity in 2–10 minutes depending on recipe and scale. Q: Can ribbon mixers handle moisture? A: They handle slightly moist blends; for high-moisture pastes, consider paddle or high-shear mixers.

Why ribbon mixers are awesome:

• Uniform blending: Double-helix ribbon creates counter-current flow for fast, consistent homogeneity.
• Low-shear action: Gentle mixing protects fragile or coated particles and minimizes heat generation.
• High throughput: Fast cycle times and efficient residence distribution reduce batch times.
• Scalability: Available from lab to large production sizes with easy scale-up.
• Energy efficient: Optimized ribbon geometry reduces motor load and power consumption.
• Versatile material handling: Works with powders, granules, flakes, and some pastes; compatible with dry and slightly moist mixes.

How ribbon mixers work:

A central shaft carries inner and outer helical ribbons. As the shaft rotates, outer ribbons push material toward the ends of the trough while inner ribbons bring it back to the center, producing a continuous counter‑flow that uniformly redistributes particles until the target mix uniformity is reached.

Common features to highlight:

• Double-helix ribbon agitator
• U-shaped stainless steel trough
• Discharge valve types: slide, butterfly, plug
• CIP/SIP or sanitary finishes for food & pharma
• Vacuum or dust collection ports
• Lifting/labor-saving loading options (hopper, conveyor)

Industries & applications:

• Food: flour blends, spices, seasoning mixes, powdered beverages
• Pharmaceuticals: API blends, excipients, tablet mixes
• Chemical: detergents, pigments, catalysts
• Plastics & masterbatch: color concentrates, additives
• Construction: cement additives, dry mortar blends
