Adelphi Group

Helical Stirrer

The Helical Stirrer is designed for applications that require gentle, controlled agitation, making it ideal for medium to high viscosity products (Up to 5000 cPs) and formulations that are particularly delicate. It is perfect for processes where the goal is creating a homogeneous solution or keeping particles in suspension rather than intensive blending.

  • 316L Stainless Steel
    Constructed entirely from hygienic 316L stainless steel, all product‑contact surfaces are finished to an exceptional 0.4 μm Ra, with ground welds to ensure superior cleanability and compliance for regulated environments.
  • Stirrer Matches the Exact Shape of your Mixing Vessel
    With a carefully engineered close‑tolerance design, the stirrer matches the exact shape of your mixing vessel, ensuring thorough, uniform mixing coverage. Operating at low speeds of 50–100 rpm, it delivers smooth, low‑shear agitation that preserves product structure, texture and integrity.
  • Customisation Options
    Configure your Spiral Stirrer to meet your exact process requirements:
    • Custom sizes tailored to your application
    • Motor options to match your mixing needs
    • Full integration with a Pharma Hygiene Products mixing vessel system
  • Engineered for Delicacy & Precision
    The Spiral Stirrer provides controlled, uniform movement ideal for materials that cannot tolerate high shear. Whether maintaining a suspension or gently homogenising sensitive formulations, this design ensures reliable, repeatable results with minimal mechanical stress on the product.
