Automatic Food Server Machine

Abstract

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.

Introduction

The text presents the design and evaluation of an automated food serving machine developed to address persistent problems in hostel messes, such as long queues, poor hygiene, uneven portioning, high food wastage, labor shortages, and intensive cleaning requirements. Traditional manual serving methods cause 30–45 minute wait times during peak hours, contribute to 40–60% food contamination, result in 25–35% food wastage, and require 8–12 workers per shift, leading to high operating costs and staff fatigue. These issues became more critical after COVID-19, increasing the demand for touchless, hygienic food service systems.

To overcome these challenges, the study proposes a compact, fully touchless automated food serving machine designed specifically for Indian hostel meals. The system dispenses rice, roti, dal, and dry sabji using dedicated mechanisms—rotary auger, conveyor-press, servo-valve spout, and rotary gate—ensuring accurate, spill-free portions. A PLC-controlled system with stepper and servo motors delivers programmable servings, while load cells track inventory in real time. The machine is built from food-grade stainless steel, supports loads over 200 kg, maintains food temperature, and includes IP65 waterproofing, caster wheels, drainage, emergency stops, and self-cleaning cycles.

Performance trials in a 500-student hostel demonstrated major improvements: serving time reduced by 60–70%, food wastage cut to under 10%, hygiene improved by up to 95%, and labor requirements reduced by about 70%. The system achieved 95% uptime and high user satisfaction (4.5–4.6/5). Although the initial cost is ?3.5–4 lakh, savings in labor and food waste allow payback within 12–18 months.

Conclusion

This research successfully demonstrates an automated hostel mess food serving machine that transforms traditional meal service into an efficient, hygienic, and cost-effective system. By integrating specialized dispensing mechanisms for rice, roti, dal, and dry sabji within a compact 134 × 112 × 165 cm footprint, the machine addresses core challenges like long queues, contamination risks, portion inconsistencies, labour shortages, and food wastage. Real-world testing in a 500-student hostel confirmed key performance metrics: 60% faster serving (20-30 seconds per meal), 30-40% waste reduction, 95% uptime, and 4.6/5 user satisfaction. The system\'s standout features touchless touchscreen interface, PLC automation, precise load-cell portioning, IP65 hygiene protection, and FSSAI-compliant materials make it reliable for daily high-volume use. Economic analysis shows full ROI within 12-18 months through ?2-3 lakh annual labour savings and ?12,000-18,000 monthly waste cuts, proving strong value for ?3.5-4 lakh investment. Beyond hostels, this scalable solution suits canteens, corporate cafeterias, hospitals, and community kitchens across India. Future enhancements could include AI demand prediction, mobile app integration, solar power compatibility, and expanded menus for global cuisines. In summary, the proposed machine sets a practical benchmark for semi-automated food service infrastructure, promoting healthier meals, happier students, and sustainable operations in resource-constrained environments.
