The RB-DM-4000 (machine designation BM 3-40) is RotoBake's largest dough moulder, built in New Delhi with a 3-set, 6-roller system for shaping dough pieces weighing 200 to 1,100 grams at under 4,000 pieces per hour. It uses 1 pressure cushion (a second is optional), a 450 mm band width, and handles dough up to 350 mm wide with a pillow length of 300 to 450 mm. Dough enters at 900 mm and exits at 750 mm, powered by a 1.5 to 2.2 kW motor on a 380–415V three-phase supply. The machine measures 900 × 5,850 × 2,065 mm and weighs approximately 320 kg. Every RB-DM-4000 ships with on-site installation, commissioning, and operator training included, backed by RotoBake's 10-year spare-parts guarantee. RotoBake has manufactured bakery machinery in New Delhi since 1964 and exports to bakeries across the Middle East, South Asia, and Africa.
