University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    DESIGN, DEVELOPMENT AND PERFORMANCE EVALUATION OF SOLID STATE COOLING MODULE FOR RAW MILK COOLING
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2019-09-03) MALLIKARJUNA; Ramachandra, C.T.
    Milk is the perfect growing medium for micro-organisms. At 4 °C microorganisms cannot duplicate and thus spoilage can be avoided. The global increasing demand for refrigeration in field of cooling and storage led to usage of more electricity and consequently release of CO2, CFC and HCF carbons over the world, contributing factor of global warming. Thermoelectric cooling is the new alternative technique used for producing cooling and heating effect. The developed solid state cooling module consist of three Peltier modules, hot and cold side heat sinks, exhaust fans and one SMPS. The solid state cooling module was developed with interior cooling volume of 4.5 and 5 L for water and milk, respectively. The dimensions of developed solid state cooling module were 460 H×330 D×20 T mm. The heat sinks were used to improve the rate of heat transfer between both sides of the module and SMPS were used to convert the alternate current of 110/ 220 V to direct current of 12 V and 10 amps. The performance evaluation of solid state cooling module was carried out with water and raw milk, the achieved temperature was 30 to 9 °C in 3 h and 37 to 17 °C in 1 min and 50 s, respectively. The COP, cooling load and power consumption of developed cooling module was 0.036, 146.188 kJ and 1.125 kWh, respectively. The developed cooling module was easy to operate, economical, green technology and eco-friendly. The B-C ratio of developed module was 1:1.18.
