Abstract: This project aims to design and develop a motorised paddy cleaning machine that effectively separates paddy dust and other impurities from grains. The traditional methods of grain cleaning are labour-intensive, time-consuming, and inefficient, posing significant challenges for farmers. The proposed paddy cleaning machine incorporates a sturdy wooden frame, a mesh sieve, and wheels for mobility. It utilises a motor to drive the sieve, facilitating the separation of debris such as sticks, leaves, stones, and dust from the harvested and dried grains. Additionally, fans are integrated into the system to blow away lightweight particles like husks and dust, enhancing the overall cleaning process.The key advantage of this machine lies in its versatility, as it is designed to handle grains of different varieties. By adapting to various grain sizes and characteristics, it enables farmers to utilise the machine across multiple crop types, promoting its widespread applicability and usability.By streamlining the grain cleaning process, the motorised paddy cleaning machine not only saves considerable time and effort for farmers but also improves the quality of the harvested grains. By utilising readily available materials such as wood, mesh, and standard components, the project aims to offer a practical and affordable solution that can be easily adopted by agricultural communities. Overall, this project endeavours to empower farmers by providing an efficient, versatile, and cost-effective solution to the challenges associated with grain cleaning. The motorised paddy cleaning machine has the potential to significantly enhance the agricultural sector's productivity, improve grain quality, and contribute to the economic welfare of the country.
