    What is a Spiral Stirrer?

    A Spiral Stirrer is a three-bladed curved stirrer that generates vertical flow in the product, generally pulling product from the bottom upwards. This is mostly used for gentle stirring rather than vigorous mixing, for example to create a homogenous solution or keeping particles in suspension, as opposed to blending powders and liquids.

    Another application could be something that is easily damaged, such as a protein, as it is a low shear stirrer that won’t damage the product. Low speed mixing, less than 500 rpm.
