ABSTRACT Groundnuts have been used since the origin of humanity. It is rich in oil and protein and has a high energy value. Oil extraction from groundnut is more common at village in most of the developing countries. Groundnut is very common and eatable item and its oil is used as a cooking medium. Also the by-product groundnut cake after oil extraction also contain 43 to 65 percent protein and 6 to 20 percent fat which is mostly used as food for cows and goats. At present there is a lack of workers in the field o f agriculture and due to more cost in harvesting. Due to the above factors, farmers are not involved in groundnut cultivation. The removing of groundnut pods is a time consuming process and cost expensive. Temperature is very high at harvesting time so people finds difficult to work. To overcome these difficulties groundnut thresher is used in groundnut pod removing process which minimize the time and cost. Key words: Groundnut Pods, Strip, Thresher, Performance Analyse
1. INTRODUCTION 1.1 GROUNDNUT
They have a rich nutty flavour, sweet taste, crunchy texture and above a relatively longer shelf life. Soil conditions in some producing regions are ideally suited for dry, clean and spotless Groundnuts in Shell. Groundnut is the major oil seed crop in India and it plays a major role in bridging the Vegetable oil deficit in the country. Groundnuts in India are available throughout the year due to a two-crop cycle harvested in March and October. Groundnuts are important protein crops in India grown mostly under rain-fed conditions. The awareness and concern for quality amongst the Indian groundnut sellers and processors are growing steadily. Multiple sorting and grading are fast becoming a norm. Indian manufacturer have the capability to prepare and supply edible peanuts conforming to highest standards. The groundnut legume is shown in the figure 1.
Groundnut or peanuts is a species in the legume or "bean" family. The peanut was probably first domesticated and cultivated in the valleys of Paraguay. It is an annual herbaceous plant growing 30 to 50 cm tall. The leaves are opposite, pinnate with four leaflets two opposite pairs; no terminal leaflet, each leaflet 1 to 7 cm long and 1 to 3 cm broad. Peanuts are known by many other local names such as earthnuts, ground nuts, goober peas, monkey nuts, pygmy nuts and pig nuts. Despite its name and appearance, the peanut is not a nut, but rather a legume. India is the second largest producer of groundnuts in the world in the order shown in the table 1. Indian groundnuts are available in different varieties as bold or Runner, Java or Spanish and Red Natal. Table 1. Production of groundnuts in different countries RANK
