Shuanglong Mixer – The Preferred Choice for Intelligent Carrageenan Processing in Chile

Customer Background:
A globally leading producer of algae-based hydrocolloids in South America, specializing in the R&D and production of Carrageenan and Agar.

Product Introduction: Carrageenan

• Natural Origin: A natural hydrocolloid extracted from specific red algae.

• Functional Properties: Thickening, gelling, stabilizing, and emulsifying.

• Three Main Types and Characteristics:

  • κ-Type Carrageenan:

    • Forms firm and brittle gels (activated by potassium ions).

    • Applications: Dairy products (chocolate milk/ice cream), meat products (water retention and elasticity enhancement).

  • ι-Type Carrageenan:

    • Forms soft and elastic gels (activated by calcium ions).

    • Applications: Dairy products (yogurt/cream), pet food.

  • λ-Type Carrageenan:

    • Non-gelling, highly effective thickening.

    • Applications: Sauces, ready-to-drink beverages, toothpaste.

• Key Advantages:

  • Clean label: Aligns with natural food ingredient trends.

  • Broad compatibility: Works across various pH and temperature conditions.

  • Synergistic effects: Enhances performance when combined with locust bean gum, etc.

• Industry Solutions:

  • Food: Replaces animal gelatin (suitable for vegan/halal certification).

  • Cosmetics: Rheology modification in toothpaste/shampoo.

  • Pharmaceuticals: Excipient for sustained-release formulations.

Model Selection:
The customer specified the NAUTA® mixer, a registered trademark of Hosokawa Micron B.V. (Netherlands), primarily used for blending powders and high-viscosity materials. The brand was later acquired and integrated into Hosokawa Micron.

• This iconic Conical Screw Mixer (Nauta Mixer) is renowned for its gentle yet efficient mixing achieved through planetary rotation and self-rotation.

• A prevalent model in the early stages of mixer development, it remains popular today due to its exceptional cost-performance ratio and flexible sizing, suitable for high-standard industries like food, pharmaceuticals, and chemicals.

Shuanglong Equipment:

As a leader in China’s mixing equipment manufacturing sector, Shuanglong Group’s DSH series (single/double/multi-screw mixers) has established a dominant market presence through decades of technological expertise. Our equipment leads the industry in adoption, a testament to our deep understanding of localized production needs and continuous engineering advancements—from material science to mechanical dynamics, every technical detail embodies the wisdom of three generations of engineers.

• Core Innovations:

  • We’ve built a comprehensive material-power matching database:

    • For powders/pastes with varying bulk densities (0.2–2.8 g/cm³).

    • Developed adaptive power algorithms (motor configurations: 0.75–315 kW).

    • Achieves optimal balance between energy efficiency and mixing uniformity (CV ≤ 5%).

• Revolution in Conical Mixer Technology:

  • From early single-motor centralized drives to modern split-rotation systems, the evolution of conical mixers mirrors China’s industrial leap:

    • Transmission Revolution (2005–2015):

      • Introduced planetary gear reducer technology, improving rotation/self-rotation control precision to ±1 rpm.

    • Material Upgrade (2016–2020):

      • Applied plasma cladding to screw blades, extending wear life by 300%.

• Transmission System Optimization & Performance:

  • Our transmission system features variable-frequency control (self-rotation gearbox + reducer), enabling flexible speed adjustment to suit different materials while reducing energy consumption.

  • The use of cycloidal reducers ensures stability, lowers costs, and simplifies maintenance.

• Long-Term Operational Validation:

  • A DSH-6 mixer (power-enhanced version) delivered in 2017 remains in stable operation at a client site:

    • Accumulated operation: 50,000+ hours.

    • Processed materials: 100,000+ tons.

    • Core components (e.g., screw blades, reducers) remain in excellent condition.

  • Compared to standard models of the same size, this unit demonstrates superior durability and cost-efficiency, delivering sustained value to customers
