Dough mixer SIGMA SAU-T-200HD

An overturnable spiral mixer automates the transfer of mixed dough from the bowl to a worktop or divider without manual lifting. A spiral-shaped agitator rotates inside a fixed bowl, kneading the dough by stretching and folding it in a continuous motion. The bowl itself tilts forward on a sturdy frame, allowing the dough to slide out under its own weight once mixing is complete, eliminating the need for operators to scoop or lift heavy batches.

To operate the SIGMA 290 L overturnable spiral mixer, the operator loads the ingredients into the bowl, closes the safety guard and selects the mixing programme. The spiral agitator begins rotating, pulling the dough towards the centre and then pushing it back outwards in a repeating cycle. Once the set time elapses, the bowl tilts forward automatically, depositing the dough onto a prepared surface or directly into a divider. The operator then resets the bowl to its upright position for the next batch.

The mixer is built on a heavy-duty steel frame, with the bowl and agitator constructed from stainless steel to withstand daily use in a professional bakery. The tilting mechanism is driven by a robust motor, ensuring smooth and controlled movement even when the bowl is fully loaded. A control panel mounted on the side of the unit allows the operator to set mixing time and speed, with safety interlocks preventing the agitator from operating when the guard is open.

A power rating of 9.95 kW indicates the load this mixer places on the electrical supply, requiring a dedicated 400 V three-phase circuit. The 290 L bowl capacity allows large batches to be processed in a single cycle, reducing the number of mixes needed for high-volume production. The unit's weight of 1650 kg means it is installed as a fixed piece of equipment, typically positioned on a reinforced floor to support its mass. Its footprint of 2300 mm long, 1470 mm wide and a height adjustable between 2150 mm and 3300 mm determines the space it occupies in the bakery layout, including clearance for the tilting bowl.

Cleaning involves removing any dough residue from the bowl and agitator after each use, using a plastic scraper to avoid damaging the stainless steel surfaces. The bowl can be tilted to its full forward position to access the underside, and the agitator can be lifted out for thorough cleaning if required. The control panel and frame should be wiped down with a damp cloth, avoiding direct water contact to prevent electrical damage.

The SIGMA SAU-T-200HD is part of the SAU line, which includes models for dough capacities of 120 kg, 160 kg, 200 kg and 280 kg. This model is positioned in the SIGMA catalogue for high-capacity bakeries requiring automated dough transfer to streamline production workflows.
