Abstract: Groundnut is one of the vital oilseed crops cultivated in India. India ranks first in groundnut area under cultivation and is the second-largest producer in the world, with 101 lakh tonnes and a productivity of 1863 kg per hectare in 2021-22. Small-scale farmers primarily cultivate groundnuts in India, which is the most predominant dryland crop. Initially, the peanuts were separated from their shells by the workers, and the output from this method was significantly less, failing to meet market demand due to its time-consuming nature. It is a time-consuming and tedious operation. Hence, a portable groundnut decorticating machine is designed and fabricated, which is small in size, easy to carry anywhere, and very easy to operate (at any time). This is more useful for domestic purposes such as households, hotels, and restaurants. This paper describes the design and fabrication of various components of a hand-operated groundnut decorticator. Small farmers or business owners can start businesses with less capital investment. The output is approximately 40-42 kg/hour, with a shelling time of 1.5 minutes per kilogram, and a high costbenefit ratio of 1:28.6. The machine is also lightweight, easy to operate, and maintain, and its spare parts are available locally. Maintenance is straightforward, the purchase cost is low, and it is highly economical to use. No electric power, diesel, or technical knowledge is required. The shelling operation can be done by women at any time, accommodating it within the house itself. Small and marginal farmers can use regular shelling for sowing groundnuts. This is convenient equipment and can be used at any time (during the day or at night) based on their convenience. Not much labour is required, and one person can manage the decortication process; it is also cost-effective.
