The Weiwei groundnut sheller is built around those two settings. Pods are poured into a hopper with an opening of 41.5 × 39.7 cm and fall into the drum, where the beaters rub them against the concave until the shells open. Kernels and husk fragments drop through the screen — 8 mm for small-seed varieties, 10 mm for larger nuts, 12 mm on request — and a fan lifts the light husks out of the discharge while the kernels fall clear into the sack. Both air inlets can be opened or closed by hand, so the operator raises or lowers the air volume to suit pod size and how dry the crop is; that one adjustment decides how much chaff travels with the kernels.
The machine measures 0.54 × 0.53 × 1.0 m and is driven by belt from a gasoline engine, a diesel engine or an electric motor — so it can work in a field with no power line, or under a shed with three-phase supply. The frame sits on small wheels and two people can push it between drying floors. It shells groundnut for seed production, for oil pressing and for confectionery lots.
Zhengzhou Weiwei Machinery has built farm machinery in Xingyang, Henan since 1980, to CE and ISO9001 standards, and ships shellers, threshers and processing lines to Africa, Southeast Asia, South Asia and the Americas.
