High-efficiency kneading solution designed specifically for high-viscosity, difficult-to-discharge materials.
Bottom discharge sigma mixer is a heavy-duty mixing machine specifically designed for high-viscosity, high-solids-content, semi-solid, or paste-like materials. Direct discharge via a bottom valve or extrusion device significantly reduces residue and improves discharge efficiency.

1. More thorough discharge
Material is discharged directly from the lowest point.
Significantly lower residual material rate compared to hydraulic tilting sigma mixer.
Especially suitable for expensive raw materials or high-value-added products.
2. More suitable for high-viscosity systems
More suitable for materials with viscosity >100,000cps or even “dough-like” consistency.
Safer as it does not rely on manual scraping.
3. Easy integration with downstream equipment
