Shelling groundnuts by hand is slow and hard on the hands, and the bruised kernels that come out lower the price paid at the oil mill. In-shell peanuts also arrive from the field mixed with stones, dust and light chaff. A proper peanut shelling line does three jobs in one flow: crack the pods, separate the kernels from the husks, and clean the kernels so they can be bagged or pressed.
At the centre of the line is the Weiwei Model 650 groundnut sheller. A 2.2 kW single-phase motor drives the drum at 800 kg/h, and the 1,300 × 650 × 1,300 mm frame fits on a small concrete pad. Dried pods feed through the top hopper, are cracked inside the shelling chamber, then drop to a double-fan winnowing section and a vibrating sieve that blow the light husks away and let clean kernels fall through the outlet. For household and smallholder use, the Model 360 does the same job at 300 kg/h on a 1.5 kW, 220V single-phase motor.
Breakage is controlled by the drum clearance and the soft-roller feed, so seeds stay whole and germination rates hold up. The two models cover the whole market: the 2.2 kW Model 650 suits oil mills and feed plants that need 800 kg/h, while the 1.5 kW, 220V Model 360 gives small farms and households a single-phase machine at 300 kg/h. Husks are collected separately and sold on as animal feed, biomass fuel or garden mulch, turning a waste stream into extra income.
