 ABSTRACT

Shelling is one of the important post harvest technology operation where the kernels are to be separated from the cobs to use as seed, fodder, and oil extraction and to prepare the value added products and also to maintain the quality of end product. The maize shellers which are manually or power operated, are used to remove the corn pearls from the cobs. But traditional maize shelling equipments are not fully effective. Also labours are not available in peak season. High wages of labour, changing environment affects the quality of maize kernels. The factors affecting maize shelling efficiency are level of moisture content in the crop, size and quality of cobs, rate of supply of cobs and the extent of the dehusking of the machine.  In view of this, it is highly essential to develop a continuous hand maize sheller for enhanced capacity with low grain broken percentage and a modified tubular hand maize sheller for the benefit of small and marginal farmers, especially for seed purposes. A more efficient shelling is achieved when the grain has been suitably dried to 13 percent to 14 percent moisture content. The physical properties of maize at moisture contents were recorded like grain mean diameter, cob mean diameter, cob length, cob width, grain cob mean weight and shelled cob mean weight. Broken seed was 1.96 per cent.

1. Spread seed was 2.23 per cent.
2. Unshelled seed was 4.25 per cent.
3. Input and Output capacity was 21.35 kg/h and 14.34 kg/h respectively.

Keywords: Sheller, Traditional method, Broken seed, Shelling efficiency etc.
