MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541113023 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Nov. 18, 2025, for 'smart onion sorting and storage system.'
Inventor(s) include S. Maheswari; S. R. Navanith; D. Naveen Kumar; and S Mohana Prasath.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "This system keeps onions safe through the rainy season by doing two simple things really well: it checks each batch before it goes in, and it keeps the storage room steady at 10-15 C once they're inside. A small conveyor outside the chamber uses a Raspberry Pi camera and soft lighting to spot bad bulbs; a gate flicks those aside so only clean sacks enter. Inside, the room is built like a compact cold space using insulated PUF/PIR panels, so it holds temperature without wasting power. Sensors watch temperature, humidity, air movement, and even gases that rise when rot starts. If gas spikes, the system first pushes that air out, then gently brings the room back to its setpoints- no harsh cycling that wears out compressors. Everything is tracked: which batch got in, what the room felt like, and what the equipment did. That history lives on a simple dashboard so teams can tune settings for their onions and season. The result is fewer surprises-less rot, less sprouting, less weight loss-without the cost and complexity of deep cold rooms. It's modular, easy to run, and ideal for small warehouses and farmer groups looking to steady supply and prices."
