of groundnut there is a need of shelling the ground nuts and obtaining the peanuts in safe, fast and economic form. The agricultural industries in our country heavy machines to do the same but the farmers in rural areas and in small industries its necessary to have a economical and high efficiency machine

The design and construction of motorized melon shelling machine using impact method was done in order to meet the domestic, commercial and industrial demand of melon for food processing and for other industrial uses. The Melon shelling machine is made up of the following main units; hopper, shelling chamber, electric motor and supporting base.

Dec 07, 2017· Design and Construction of Melon Shelling Machine. Mellon seeds are an important oilseed that meets the needs of many foods. The shelling of this crop is crucial until it is used in large quantities. To solve the melon-related challenges, a muskmelon harrow was designed and built.

The machine was tested with melon seeds at constant speed and feed rate, using moisture contents of dried seeds, 5%, 10%, 15%, 20% and 25% by weight (w.b). The melon shelling efficiency (MSE) increased as the moisture content increased, but beyond 20% w.b, there was a decrease. The maximum shelling efficiency was obtained at a moisture content ...
