Mixing

The Modulomix horizontal paddle mixer consists of a cylindrical process chamber with a central shaft fitted with paddles that rotate at a fixed clearance from the chamber wall. The paddles generate both axial and radial motion, continuously conveying the powder forward and backward for rapid, homogeneous mixing.

The intensive agitation regime achieves complete mixing with very short residence times, enhancing energy efficiency while maintaining product integrity. Although high shear can be applied, particle attrition is limited by the paddle geometry and controlled clearance.

Rotor speed and paddle configuration can be adjusted to suit specific product characteristics and mixing objectives. For example, blending magnesium stearate requires a different mixing regime than drug or excipient blending — easily managed by cascading multiple Modulomix units in series.

The Modulomix is also well-suited for coating applications. For instance, many difficult-to-wet proteins can be instantised with the addition of less than 1% lecithin surfactant, while calcium carbonate powders can be encapsulated or rendered hydrophobic with a coating of less than 1% stearate powder.

distinct regimes — gentle pre-mixing, high-intensity dispersion, post-conditioning — you can cascade Modulomix units in series. Each stage operates with its own speed, residence time and paddle geometry, forming a compact, scalable train that delivers consistent quality, precise control and reliable scale-up.
