    Design and fabrication of pea depoding machine
    (Punjab Agricultural University, Ludhiana, 2011) Parminder Kamboj
    Agro processing is regarded as a sunrise sector of Indian economy in view of its large potential for employment and income generation. In India, post- harvest processing of agricultural produce is very low in comparison to other countries, which may be mainly due to lack of processing technologies. There is a dire need to develop more processing machinery for value addition of agricultural produce with a reduction in time and labour. Pea is an important cool season, leguminous crop of India. Manual removal of peas from pods is a labourious and time consuming job with one person depod about 3-3.5 kg of peas from pods in one hour. In view of non-availability of efficient pea depoding machine work on design and fabrication of power operated pea depoding machine was undertaken by Department of Processing and Food Engineering, Punjab Agricultural University, Ludhiana. Computer aided design of machine was made by using “Solid Works” software. The machine is based on the principle of friction generated by the rubbing of pea pods between the blade and the sieve of the machine which helps in opening the pods of pea grains. The model of machine was fabricated by using the low cost material available in the market and computer aided design helps to find dimensions of various components of machine in very small time. A simulation model of machine was made, which gives very fine representation of machine components. Performance evaluation of machine was done to optimize these machine parameters by such as RPM of blades shaft, blade size and clearance between sieve and blades. Based upon performance analysis the depoding efficiency of pea was 95.4% and whole grain efficiency of peas was 91.3% with grain damage of 2% was obtained at 60 RPM and 10 mm clearance between blades and sieve by using blades of 2.5” size aligned at angle of 1800 with respect to each other. This machine is simple in design and is capable of extracting 30 kg/h of shelled peas. This technology will save time and labour and will provide maximum benefits to the farming community by enhancing their income
