MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641061134 A) filed by Sona College Of Technology, Salem, Tamil Nadu, on May 14, for 'automatic pneumatic grain de-husking machine.'
Inventor(s) include V. Kaviarasan; R. Vignesh; and M. Pradeepkumar.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an automatic pneumatic grain de-husking machine (100) for removing the outer husk from agricultural grains such as paddy, maize, millet, and pulses. The machine comprises a grain hopper (101), a de-husking chamber (102) including a mortar (103), a pneumatic cylinder (104) connected to a reciprocating pestle (105), a die member (106), and a blower-based separation system (109). Grains introduced through the hopper are held within the mortar where the pneumatically actuated pestle repeatedly applies controlled impact force to loosen and remove the husk while minimizing grain breakage. A secondary pneumatic cylinder (107) may assist in auxiliary operations such as discharge or chamber resetting. The processed mixture is directed to a separation chamber (108) where airflow generated by the blower separates lighter husk particles from heavier de-husked grains. The invention provides a compact, cost-effective, and energy-efficient agricultural processing machine suitable for small and medium-scale farming applications."
