LiviNest Hand Corn Sheller — Cast Iron Manual Thresher with Adjustable Screw & Wooden Handle, 40-60 kg per hour, 98% Kernel Recovery

Designed for classroom and outdoor demonstrations, this LiviNest manual hand-crank corn sheller lets educators teach traditional shelling techniques without electricity, so students aged 8+ can safely take part in hands-on lessons. Built from heavy-duty cast iron with a reinforced A-frame stand (17.5"H × 12"W × 11"D), the unit withstands frequent student use; its 12.8 lb weight helps keep it steady during operation and the orange enamel finish resists rust from outdoor storage. The adjustable screw mechanism adapts to small through large cobs, delivering 40-60 kg per hour throughput with 98% kernel recovery. Mechanical cob ejection reduces interruptions and handling, keeping demonstrations flowing. Beyond corn shelling, the sheller also effectively hulls walnuts for comparative agricultural activities. The wooden handle and fully mechanical operation provide an authentic, hands-on experience that supports lessons in farming history and traditional food preparation.
