Seed Grading Screen Sieve Punching & Wooden Frame Fabrication

Kisan Beej Chhalni Screen & Sieve Manufacturing Works

Seed processing plants and village grain grading units cannot separate weed seeds, chaff, and undersized kernels without screens punched with exact, microscopic slot dimensions. Standard round perforations let oblong pulse seeds slip through, while warped wooden frames cause seed lots to bypass screens and contaminate certified seed bags. This specialized workshop uses mechanical turret punch presses to punch precise oblong, slotted, and round perforations into galvanized zinc and brass sheets. The carpenter crafts sturdy, mortise-and-tenon wooden frames from seasoned, warp-free timber, tensioning the perforated metal sheets with heavy brass staples and steel edge bands. Seed processors, grain cleaning mills, and agricultural universities order customized sieve sets matched to exact seed varieties like chickpea, mustard, or wheat. Operators appreciate durable frames that slide snugly into seed cleaner shaker shoes without vibrating loose or leaking grain.
