Bechamel Sauce Sigma Mixer High Quantity Sigma Mixer

It handles high-viscosity, sticky, and heat-sensitive food mixtures with intensive kneading, folding, and shearing actions. This thoroughly incorporates roux, milk, cream, butter, cheese, and seasonings into a smooth, lump-free, homogeneous, and velvety sauce with consistent texture and superior quality.

The mixer is available in Stainless Steel 316, Stainless Steel 304, and Mild Steel. Stainless-steel versions can be polished to matt or mirror finish as required. Mild-steel units receive one coat of red oxide primer followed by two coats of epoxy paint. PTFE shaft sealing ensures food-grade compatibility.

Tangential ‘Z’-type (Sigma) kneading blades rotate accurately at different speeds (typically a 3:2 ratio) toward each other. This creates bulk movement, stretching, folding, dividing, and recombining of the material, along with shearing against the blades and side walls for thorough mixing and a uniform sauce consistency.

Discharge can be performed manually via a hand-wheel-operated mechanism or automatically via a hydraulic tilting system. Additional options include bottom valves or a screw extruder for efficient and controlled product removal.

Yes. An optional jacket for heating or cooling can be fitted, complete with mineral-wool insulation and cladding. This supports precise temperature management for melting fats, dissolving ingredients, or cooling the batch while ensuring excellent heat transfer.

Models range from ASM-50 (approx. 50 L working / 80 L gross capacity) to ASM-3000 (approx. 3000 L working / 3800 L gross capacity). Motor power is offered in general and heavy-duty ratings (from 5–7.5 HP up to 100–120 HP). Voltage can be adjusted to match local power requirements.

It delivers batch-to-batch consistency even at 1–3 tons per batch, reduced cooking time through excellent heat transfer and constant mixing, minimal product loss with easy CIP cleaning, the ability to add cheese, cream, spices, or stabilizers in the same vessel, and optional ATEX explosion-proof versions for flour-dust zones.

Tangential ‘Z’ blades maintain a minimum gap between the trough inner shell and blades to eliminate sticking. The robust construction, PTFE seals, and optional spray or vacuum systems further enhance hygiene, mixing efficiency, and product quality.

Optional features include a liquid spray system, vacuum system (to remove air bubbles and improve stability), blade cooling arrangements, hydraulic tilting discharge, variable-speed drives, computerized controls, and safety interlocks for greater process flexibility and efficiency.
