Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Design, development and performance evaluation of laboratory scale hydrodynamic cavitator
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Bhore, Nilesh Shivaji; Lohani, U.C.
    The present study entitled, “Design, Development and Performance Evaluation of Laboratory Scale Hydrodynamic Cavitator” was conducted in the department of Post-Harvest Process and Food Engineering, G.B.P.U.A.T, Pantnagar, Uttarakhand during 2016-18. Agriculture is the backbone of the Indian economy because 75% of India’s population depends on agriculture or agro-industries for livelihood. Thus, there is a huge amount of agricultural residues generated in Indian farms which are either unutilized or burnt in open farms causing environmental problems. With the annual Indian production of fruits and vegetables alone estimated as 243 million tons, assuming the processing levels at 2% for the organized sector and 30% residue generation, one could expect generation of about 1.45 million tons of fruits and vegetables processing waste annually in India alone. One of the most beneficial approaches is to recover the bioactive constituents, especially the phenolic compounds, making full use of them in the nutraceuticals/functional foods, medicines, pharmaceuticals and cosmetics industries. Hydrodynamic cavitation is one such innovative technology which can be used for extraction of valuable bioactive compounds from agricultural and horticultural waste. Therefore, the present research work was undertaken for design, development and performance evaluation of laboratory scale throttle valve based hydrodynamic cavitator. The experiments were conducted to study the effect of process parameters on cavitation characteristics for optimum performance of cavitator. A full factorial design with three independent variables at three levels was used for conducting the experiments. The independent variables selected were throttle valve open area (22, 42 and 62%), number of passes (5, 10 and 15) and downstream elevation (2, 2.5 and 3 m). The cavitation number, cavitation yield (g/J), and output product temperature (ºC) were analysed. The data from all 27 experiments were analysed using Design Expert 10.1.1 and the response functions were developed using multiple regression analysis. The optimum level of variables of process parameters obtained for optimum performance of cavitator were 22% throttle valve open area, 5 number of passes and 3 m downstream elevation. The optimum values of responses were of 0.5 cavitation number, 2.76 x10-7g/J of cavitation yield and 33.1ºC output product temperature. Significant (p<0.05) effect of process parameters were found in all responses. On validation of the model for optimum performance of cavitator, it was found that the model was accurate as the prediction error was only in the range of - 4.16 to 13.2%.
