Dough sheeter ROLLMATIC DIRO DR-S/52

A sigma-arm dough divider rounder automates the portioning and rounding of dough pieces by passing them between rotating rollers and a shaping belt. The rollers press the dough into uniform weights, while the belt rounds each piece into a smooth ball, ready for proofing. This method eliminates manual scaling and hand-rounding, reducing labour and ensuring consistent results across batches. The process relies on calibrated pressure and speed settings, which can be adjusted for different dough types and hydration levels, making it suitable for bread, rolls, and sweet doughs alike.

The DIRO DR-S/52 is operated via a 4.5-inch touchscreen that stores up to four programmes, each saving pressing parameters and hopper height settings. To begin, the operator loads the hopper with dough, selects the desired programme, and activates the rounding cycle using the front-mounted pedal. The pedal replaces a traditional handle, freeing both hands for handling dough and reducing the machine's footprint. Once activated, the rollers divide the dough into equal portions, which are then rounded by the belt. The operator removes the finished balls from the discharge tray, ready for the next stage of production.

Constructed with three rollers, the DR-S/52 is built from stainless steel and engineered for continuous use in professional bakeries. The touchscreen interface allows for quick adjustments to pressing force and hopper height, accommodating different dough consistencies. A built-in cleaning cycle simplifies maintenance, flushing out residual dough and reducing downtime between batches.

The 400 V power supply requires a three-phase circuit, standard in commercial bakery setups. At 255 kg (net) and 278 kg (gross), the unit is heavy but designed for mobility: two handles and a lever-activated wheel set (sold separately) allow the machine to be lifted and rolled for floor cleaning. Its 96 x 98 cm footprint fits into most bakery workspaces, while the 182 cm height ensures ergonomic loading and unloading.

The DR-S/52 is a semi-automatic model, meaning it requires operator input for loading and unloading but automates the dividing and rounding processes. It is part of Rollmatic's DIRO series, positioned for medium-volume production where consistency and speed are critical.
