Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Utilization of seed from tomato processing industry for extraction of oil
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Nirmala; Attkan, Arun Kumar
    The study was conducted for utilization of seed from tomato processing industry for extraction of oil. The tomato waste was dried to a moisture content of 7% (wb.). Seeds were separated using hammer mill and gravity separator. The two oil extraction techniques, temperature controlled water bath, ultrasound assisted solvent oil extraction method. The process parameters for TCWBM were extraction temperature (20, 25 30℃), extraction time (6, 8, 10min), solid to solvent ratio (1, 5, 10) and mean particle size (0.25, 0.55, 0.85mm). The process parameters for UASOEM were extraction temperature (40, 50 60℃), ET, extraction time (25, 35, 45min), solid to solvent ratio (5, 7.5, 10) and mean particle size (0.25, 0.55, 0.85mm). RSM was employed for optimizing the process parameters. The effect of process parameter was seen on oil yield, extraction efficiency and oil quality (API0). Maximum OY of 25.47%, EE of 93.1% and API gravity of 26.18 was found for UASOEM. RSM was employed for optimization of process parameters. The optimum process parameters for TCWBM obtained were 30˚C, 8min, 4.6 and 0.25mm of mean particle size and optimum OY of 14.48%, EE of 58.42% and API gravity of 24.93, with the desirability of 0.79 and for UASOEM obtained were 49.7˚C, 38.7min, 6.3 and 0.42mm of mean particle size and optimum OY of 18.20%, EE of 86.36% and API gravity of 26, with the desirability of 0.80. The cost economics of oil extraction was evaluated on the basis of economic indicators viz. breakeven point (313.4litre), payback period (0.8yr/ 9 months, 18days) and operating cost of (790 Rs./liter) of tomato seed oil at selling price of Rs. 1500/liter. The physicochemical properties such as density, specific gravity, saponification value, iodine value, color, sulfur content and fat content of oil were analyzed. It can be concluded that tomato seed is a potential source of oil. It will minimize the problem of utilization of tomato processing waste.

    Development and Performance Evaluation of Machine for Dehulling of Hempseed (Cannabis sativa L.)
    (hisar, 2022) Mittal, Vipul; Gupta, Ravi
    The study was conducted to develop a hempseed dehuller machine for dehulling of hempseed (Cannabis sativa L.). The development of the machine was based on a 2D design made from AUTOCAD software. The raw hempseeds were cleaned and graded for observation of their engineering properties. To study the effects of dehulling process variables on the dehulling efficiency of hempseeds, two seed grades: Medium (3 – 3.5 mm), Large( ≥ 3.5 mm), four levels of valve opening (100, 75, 50 and 25 % ) and five levels of initial seed moisture content (2-4, 4-6, 6-8, 8-10, 10-12 %) (wb) were selected by conducting preliminary trials. Statistical analyses viz., correlation and regression analysis of the responses was performed to estimate the coefficients of the fitted equation of the responses and to check the significance of the regression coefficients of independent and interaction variables, respectively. A three-phase (0.75 kW) electric motor was used for the power supply of the machine. The performance of the dehuller was found optimum at 2100 rpm, feed valve opening of 50% and fed with raw hempseeds of medium grade at 6-8 % MC range. At these levels of independent variables the throughput capacity, dehulling efficiency, output capacity and broken were found to be 67.4 kg/h, 38.7%, 26.25 kg/h and 8.84%. The break-even point, benefit-cost ratio and payback period for the machine were found to be 4223 units of hemp kernel, 1.029 and 0.237 years respectively. The developed machine for dehulling of hempseed was found energy-efficient, economically usable, and capable of maintaining the good quality of hempseed kernels.
