MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641024540 A) filed by Dr. R. M. Muthuraman; Mr. K. Vallarasu; Logeshkumar T; Kathiresan M; and Moongilthisipiriyan T, Erode, Tamil Nadu, on March 2, for 'design and fabrication of multi-crop seeds cleaner suitable for small scale farming.'
Inventor(s) include Dr. R. M. Muthuraman; Mr. K. Vallarasu; Logeshkumar T; Kathiresan M; and Moongilthisipiriyan T.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "Design and fabrication of multi-crop seeds cleaner suitable for small scale farming is the proposed invention. Agriculture forms the backbone of the Indian economy, with most farmers belonging to small and marginal categories who often face challenges in obtaining clean and pure seeds for cultivation. The presence of impurities such as stones, chaff, dust, husks and broken seeds greatly affects seed quality, reduces germination rate and ultimately impacts crop yield. Manual cleaning of seeds is not only time-consuming but also labor-intensive and inconsistent in quality. To overcome these problems, this project focuses on the design and fabrication of a multi crop seed cleaner suitable for small-scale farming operations. The proposed machine is designed to separate impurities from various types of seeds including paddy, wheat, maize, pulses and millets by employing both mechanical sieving and air aspiration techniques. The working principle of the machine is based on the difference in physical properties such as size, shape and density between good seeds and unwanted materials. The seed cleaner consists of a feed hopper with an adjustable gate for uniform feeding, a set of vibrating sieves of varying apertures and an air blower system."
