Automatic Food Server Machine

This research introduces an innovative automated hostel mess food serving machine designed to dispense multiple food varieties rice, roti, dal, and dry sabji in precise, hygienic portions, addressing inefficiencies in traditional serving systems. The compact system (134 × 112 × 165 cm footprint) integrates four specialized compartments: rice (54 × 36 cm) with a rotary auger dispenser for volumetric control; roti (55 cm diameter) using a conveyor-press stack release mechanism; dal (40 cm diameter) via a servo-controlled valve spout for flow regulation; and dry sabji (62 × 46 cm) employing a rotary gate for bulk dispensing. Constructed with a stainless-steel inner frame for structural integrity (load capacity >200 kg) and an insulated outer enclosure for contamination prevention, the machine features IP65-rated components, caster wheels for mobility, integrated drainage, and a centralized electrical control panel with PLC-based automation. Motorized actuators (stepper/servo motors, 24V DC) enable programmable portioning (e.g., 200g rice, 4 rotis/serve), reducing wastage by 30-40% and serving time by 60% compared to manual methods. User interface includes a touchscreen HMI for menu selection, hygiene monitoring, and real-time inventory tracking via load cells. Safety features encompass emergency stops, food-grade materials compliant with FSSAI standards, and self-cleaning cycles. Preliminary testing in a 500-student hostel demonstrated 95% uptime and user satisfaction ratings above 4.5/5. This scalable solution mitigates labour shortages, enhances portion control, and maintains hygiene in high-volume settings like hostels, canteens, and institutional kitchens, paving the way for semi-automated food service infrastructure
