Dough sheeter ROLLMATIC DIRO DR-A/30s

A sigma-arm automatic divider rounder transforms bulk dough into uniform balls ready for proofing or shaping. Three rotating cylinders grip the dough, portion it by volume, then roll each piece into a smooth sphere under controlled pressure. The method eliminates manual scaling and rounding, giving every portion the same weight, texture and rise without operator variation.

The DIRO DR-A/30s loads a batch of dough into the hopper. A touch-screen interface displays stored programmes; the operator selects one by name or creates a new setting for portion size, pressing force and hopper height. Once started, the machine divides, rounds and deposits the balls onto a conveyor or tray at a steady rate. The operator monitors the cycle, adds dough as needed and removes the finished portions.

Construction is stainless steel throughout, with two side handles and a lever-activated trolley (sold separately) that lifts the unit clear of the floor for cleaning. A 4.5 in colour touch-screen stores up to twelve programmes, each holding portion parameters and hopper settings.

The 0.75 kW motor draws a 400 V three-phase supply, typical of larger bakery equipment. The 255–278 kg weight requires a solid floor and two-person handling; the 96 × 98 cm footprint fits a standard worktop depth. Capacity of 2,700 pieces per hour matches medium-volume production lines.

Daily upkeep involves wiping the cylinders and hopper with a damp cloth, then drying to prevent dough adhesion. The touch-screen is cleaned with a soft, dry microfibre cloth. Programme settings are reviewed weekly to ensure portion consistency across shifts.
