Sigma Mixer Line Toilet Soap Kneading Mixer

It handles tough, sticky, high-viscosity materials such as soap noodles/base chips along with fragrances, colorants, fillers, and additives to produce homogeneous blends for toilet soap bars. It is optimized for dense, dough-like formulations.

The mixer is offered in Mild Steel (MS), Stainless Steel 304 (SS 304), or Stainless Steel 316 (SS 316). Finishes can be customized from matte to high-gloss. Mild steel units receive an anti-corrosive red oxide base coat plus dual epoxy top coats. PTFE shaft seals ensure sanitary, food-grade compatibility.

Precisely synchronized differential-speed ‘Z’-profile (sigma) agitators create tangential kneading motion for continuous axial material transfer. The process combines mass displacement, stretching, folding, splitting, and re-merging with intense shearing against the blades and trough walls, delivering uniform homogeneity while minimizing dead zones.

Tangential ‘Z’ blades (typically running at a 3:2 speed ratio) are ideal for high-viscosity sticky materials like soap dough. Overlapping blades (same speed) suit lower-viscosity free-flowing substances. The ultra-tight clearance between blades and trough prevents product buildup.

Models range from ASM-50 (50 L working / 80 L gross, 5–7.5 HP) to ASM-3000 (3000 L working / 3800 L gross, 100–120 HP). Intermediate sizes include 75 L, 100 L, 150 L, 200 L, 400 L, 500 L, 750 L, 1000 L, 1500 L, and 2000 L, with general and heavy-duty motor variants. Voltage can be customized.

Discharge is available via manual hand-wheel tilting, automated hydraulic tilting, bottom-mounted outlet valves, or a lateral extrusion screw. These options suit different viscosities and production preferences.

Yes. Adaptable temperature jackets allow internal heating or cooling. The trough is insulated with high-density mineral wool and clad externally. Optional blades cooling arrangements further support temperature-sensitive processes.

Optional systems include a liquid spray system, vacuum processing unit (for de-aeration), blades cooling arrangement, screw/extrusion system, and automatic valve discharge system. Modular configurations can be supplied on request.

While optimized for toilet soap manufacturing lines, it is also widely applied in the pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries for high-viscosity mixing and kneading tasks requiring consistent homogeneity.
