DESIGN AND FABRICATION OF PADDY FILLING MACHINE FOR BAGS FILLING

Mechanical Engineering

In modern agriculture, efficient packaging systems are essential for reducing labor cost and increasing productivity. This paper presents the design and fabrication of an automated paddy bag filling machine developed to improve speed, accuracy, and hygiene in grain packaging operations. Conventional manual filling methods are slow, labor-intensive, and often result in weight variation, grain spillage, and contamination. To address these limitations; the proposed machine combines vacuum conveying, controlled grain discharge, sensor-based filling, and automatic sealing in a compact and user-friendly unit. A vacuum pump transfers paddy from storage to the hopper through a flexible suction line, minimizing manual handling and material loss. The hopper discharge is regulated through a control valve, while sensors and a programmable control unit ensure accurate bag filling through dual outlet nozzles. An automatic sealing mechanism completes the packaging cycle efficiently. The fabricated prototype was tested under practical conditions and showed reduced filling time, improved weight consistency, lower spillage, and decreased labor dependency compared with traditional methods. The machine offers an economical, scalable, and efficient solution for farms, rice mills, and small packaging industries, thereby supporting agricultural mechanization and modern post-harvest processing.
