Ribbon Blender
Shrijee Nut Company's Ribbon Blender is a high-efficiency, food-grade mixing machine designed to homogeneously blend dry powders, granules, pastes, and viscous materials in peanut butter and food processing operations. The counter-directional inner and outer ribbon helices create a gentle yet thorough mixing action, achieving uniform blends in short cycle times with minimal product degradation.
Used for blending additives, stabilisers, salt, and sugar into peanut butter, as well as mixing spice blends and dry food ingredients, this machine is an essential component of a complete peanut processing facility.
The Ribbon Blender by Shrijee Nut Company features a horizontal U-trough mixing vessel with a twin-helix ribbon agitator assembly. The outer helical ribbon moves material from the ends toward the centre, while the inner helical ribbon moves material from the centre toward the ends — creating a counter-flowing, thorough mixing action that achieves blend uniformity of ±5% or better in 10–15 minutes.
Constructed entirely from food-grade SS304 or SS316 stainless steel with polished internal surfaces, the Ribbon Blender is easy to clean and compliant with food safety requirements. It is ideal for blending peanut butter additives, dry ingredients, and food formulations requiring consistent, uniform mixing.

- Achieves ±5% blend uniformity in 10–15 minutes
- Food-grade SS304/SS316 construction with polished interior
- Handles dry powders, granules, pastes, and semi-viscous materials
- Full-length bottom discharge for complete product evacuation
Counter-Directional Ribbon Mixing
Inner and outer counter-directional helical ribbons create continuous material cross-flow, achieving thorough, homogeneous blending in minimal cycle time.
Gentle Mixing Action
Low-shear ribbon design handles fragile granules, flakes, and coated particles without breaking or degrading the product structure during mixing.
High-Volume Batch Capacity
Available in capacities from 100 L to 1000 L, the Ribbon Blender supports small pilot batches through to large industrial production volumes.
Full-Length Bottom Discharge
Full-length butterfly or slide gate discharge valve enables rapid, complete product evacuation with minimal residue, reducing cleaning time between batches.
Heating/Cooling Jacket Option
Optional jacketed trough allows mixing under controlled temperature conditions for temperature-sensitive food formulations or heated peanut butter blending.
Easy Clean Design
Removable end covers, polished interior surfaces, and full-access cleaning doors facilitate thorough CIP or manual cleaning, minimising cross-contamination risk.
Ingredient Loading
Ingredients are loaded into the blender trough through the top cover or loading ports. Major ingredients are typically loaded first, followed by minor components for even distribution.
Ribbon Mixing Cycle
The twin ribbon agitator rotates, creating counter-directional material flow — outer ribbons move product inward while inner ribbons move it outward — achieving thorough blending throughout the batch.
Blend Uniformity Achieved
After the set mixing time (typically 10–15 minutes), the blend reaches ±5% uniformity, confirmed by the pre-programmed cycle timer or optional in-line sensors.
Complete Discharge
The full-length bottom discharge valve opens and the blended product is completely evacuated from the trough, ready for filling, packaging, or downstream processing.

Thorough Blend Uniformity
Counter-directional ribbon action achieves ±5% blend uniformity across the entire batch in 10–15 minutes, ensuring consistent product quality in every production run.
Gentle Product Handling
Low-shear ribbon design mixes without breaking fragile peanut granules or damaging ingredient particle structure, preserving product quality and appearance.
Hygienic Food-Grade Design
Full SS316 mirror-polished construction with easy-clean access and CIP-compatible design meets food safety standards for direct food contact mixing applications.
Versatile Application Range
Handles dry powders, granules, pastes, and semi-viscous peanut butter mixtures, making it the single solution for diverse mixing and blending needs in the processing facility.
Easy Clean & Low Maintenance
Full-length bottom discharge, removable covers, and polished surfaces minimise cleaning time between batches, reducing downtime and cross-contamination risk.
Energy Efficient Operation
Geared motor drive with optional VFD speed control delivers high mixing efficiency at low power consumption, keeping operating costs minimal across continuous batch production.
