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.

    Development of a dehumidified air dryer
    (CCSHAU, 2011) Pandhari, Sandeep Chavan; Garg, M.K.
    The present investigation entitled “Development of a dehumidified air dryer” was carried out with the objectives to development of a dehumidified air dryer and to test the performance of the dehumidified air dryer for drying of cauliflower. The development of dryer was based to maintain the low relative humidity in the drying chamber at the range of 35-450C temperature. The drying performances of heat pump dryer were compared with tray dryer. The temperature and relative humidity were recorded inside and outside of the dryer. The relative humidity were observed lower than ambient air in heat pump dryer as compared to relative humidity of the tray dryer. The rehydration ratio, nutritional characteristics, reconstitutional quality and their physic-chemical parameters of the dehydrated cauliflower were better in the heat pump dryer as compared to tray dryer. Drying in heat pump dryer at 400C took less time compared to tray dryer at 500C and 550C. The energy consumption of heat pump dryer for 24 hours of operation was found less (6, 7.5 kWh) than tray dryer (7.25, 7.8kWh) and cost of drying was found to be more in tray dryer at 50 and 550C as compared to 400C in heat pump dryer. All the analysis justifies that dehumidified air dryer did improve the quality of dried food. By using it, the products owned less browning colour, better texture, retention of nutrients and increased overall acceptability, So the dehumidified air dryer is best alternative in food industries for drying fruits and vegetables.
