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 AND DEVELOPMENT OF TUNNEL TYPE SOLAR DRYER FOR DEHYDRATION OF ONION AND AMLA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-08-12) PRIYANKA, U.; A. Carolin, Rathinakumari
    Solar tunnel dryer of 6x3x2.7 m (LxWxH) with galvanized frame structure was constructed and covered with 200 micron UV-stabilized LDPE sheet. Two fresh air inlets of 0.6 x 0.3 m size and two exhaust fans each of 9 inches dia and 50 watt capacity were installed at the rear side and front side of the dryer, respectively. The amla pretreated with 2 per cent sodium chloride and 0.1 per cent potassium meta-bi-sulphite and onion pretreated with 0.25 per cent potassium meta-bi-sulphite were subjected for drying. In solar tunnel dryer, the drying required 12-15 h and 13-14 h for various pretreated amla segments and onion slices to reduce from moisture content of 422.32- 521.46 per cent (d.b.) to a safe moisture content of 17.01-17.39 per cent (d.b) and from moisture content of 572.92 -797.29 per cent (d.b.) to attain a safe moisture content of 6.08-6.24 per cent (d.b), for amla and onion, respectively. Chemical analysis indicates that the quality of solar tunnel dried products are superior to open sun dried products .The vitamin-C retention was found to be highest (125.68 mg/100g) in untreated amla samples dried in solar tunnel dryer. The highest total phenolics, FRAP was found to be 325.09 (μg/g) and 1617.09 (μg/g), respectively in 0.25 per cent KMS pre-treated onion dried in solar tunnel dryer. The payback period for amla is 6 months and for onion it is 9 months. The results showed that the rehydrated products could be well utilized for substituting the fresh product in off season.
