MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641007439 A) filed by R. M. K. Engineering College, Chennai, Tamil Nadu, on Jan 26 for 'solar powered winnowing machine for efficient separation of grains and husks using airflo.'
Inventor(s) include Mr Ravi Kumar M.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a solar powered winnowing machine designed for efficient separation of grains and husks from agricultural chaff. The machine comprises a funneled input port for receiving chaff, a vertical guiding pipe, and at least two output ports configured to separately collect cleaned grains and removed husks. Multiple fans are mounted at different levels of the machine and oriented at optimized angles to generate controlled airflow. As the chaff passes through the vertical pipe, the airflow produced by the fans selectively blows away lighter husks while allowing heavier grains to fall naturally due to gravity. An optimized opening positioned opposite the fans provides a direct flow path for the expelled husks. The system operates using solar energy, ensuring low power consumption and suitability for rural and off-grid environments. The invention offers a cost-effective, eco-friendly, and portable solution that reduces manual labor, improves separation efficiency, and supports sustainable agricultural practices."
