Super Votator in Butter Production & Margarine Production
Function & Advantage of Super Votator
Role in Butter Production
Butter is a water-in-oil emulsion (~80% fat) that requires controlled cooling and crystallization for optimal texture and spreadability.
Key Applications:
Rapid Cooling & Fat Crystallization
The votator quickly cools cream or melted butter from ~40°C to 10–15°C, promoting the formation of β' crystals (small, stable fat crystals that ensure smooth texture).
High shear prevents large crystal formation, avoiding graininess.
Working/Texturizing
Some systems integrate the votator with a pin worker or kneading unit to further refine butter texture, improving spreadability and mouthfeel.
Continuous Processing
Unlike traditional batch churning, votators allow high-speed continuous production, increasing efficiency and consistency.
Advantages Over Traditional Methods:
Faster cooling → Better crystal structure control
Reduced fat separation → More uniform product
Higher throughput → Suitable for industrial-scale production
Role in Margarine Production
Margarine (an oil-in-water emulsion, often plant-based) relies heavily on votators for structuring fats and stabilizing emulsions.
Key Applications:
Emulsion Cooling & Crystallization
The oil blend (e.g., palm, soybean, or sunflower oil) is hydrogenated or interesterified to achieve the desired melting profile.
The votator rapidly cools the emulsion (~45°C → 5–20°C) under high shear, forming β' crystals (ideal for smoothness, unlike β crystals, which cause sandiness).
Plasticity & Spreadability Control
Adjusting cooling rate, shear force, and pressure modifies hardness, making it suitable for different applications (e.g., table margarine vs. bakery margarine).
Low-Fat & Dairy-Free Variants
Super votators help stabilize water-in-oil emulsions in low-fat spreads (40–60% fat) by ensuring proper crystallization and preventing phase separation.
Advantages in Margarine Production:
Prevents coarse crystals → Smoother texture
Enables flexible formulations (plant-based, trans-fat-free, etc.)
Improves shelf-life stability by optimizing fat crystal network

Industry Examples
Butter Production:
APV, Gerstenberg Schröder, Alfa Laval and Shiputec supply votators for continuous butter-making lines.
Margarine/Spreads:
Used in plant-based margarine (e.g., made with palm or coconut oil) to mimic dairy butter’s melting behavior.
Key Considerations for Optimization
Cooling rate & shear force must be adjusted based on fat composition.
Worn scrapers reduce efficiency → Regular maintenance is critical.
Pressure settings affect emulsion stability (especially in low-fat spreads).
Conclusion
Super votators are indispensable in modern butter and margarine production, enabling:
Faster, continuous processing
Superior texture control (no graininess, ideal spreadability)
Flexibility for dairy & plant-based formulations
By optimizing cooling and crystallization, they ensure consistent quality in high-fat products while meeting industrial-scale demands.
