    Energetics and techno economic assessment of different paddy straw densification processes
    (CCSHAU, 2018) Hemant Kumar; Vijaya Rani
    In India, a large portion of the residue is burnt on-farm primarily to clear the field for sowing of the succeeding crop. The burning of straw creates health, soil and environment hazards. From the total crop residue, cereal crops (rice, wheat, maize, and millets) contribute 70% while rice crop alone contribute 34%. Management of this huge amount of paddy straw becomes difficult for farmers. Many solutions are being tried to manage the paddy straw one of them is straw removal from field by making bales which can be easily handled and transported for animal feed, power generation, brick kiln etc. In the present study different densification process viz., using field baler after operation of stubble shaver with and without operation of hay rake. In third case loose straw was directly collected from field and baled by field baler in stationary mode. Further, full length straw and chopped by chaff cutter was used to make bale in hydraulic pressed type fixed stationary. In the study it was found that, if the harvesting of paddy is done by combine, then operating field baler after operation of stubble shaver and hay rake was most appropriate providing a maximum field capacity of 0.54 ha h-1, baling capacity 4.43 t h-1, volume compaction ratio of 5.26 with minimum time required of 0.44 h, man-h 3.57, energy of 102.65 MJ t-1 and cost of baling Rs 624 t-1. The scented variety of rice is mostly harvested manually for which the full length densification by a hydraulic press type fixed baler is appropriate with baling capacity 1.13 t h-1, maximum volume compaction ratio 6.87 and lowest cost of operation Rs 595 t-1. The transportation, storage become easy and safe with bales than loose straw. Maximum benefit was obtained with stationary baler for full length straw.

    Effect of ohmic heating on oil recovery from rice bran
    (CCSHAU, 2018) Ashwini S.C.; Garg, M.K.
    This study describes a new technological method for rice bran oil extraction. The method deals with the combined effect of ohmic heating and enzyme assisted aqueous oil extraction process (EAEP) on improvement of oil recovery from Rice bran. The experimental procedure consisted of following fundamental steps, i.e., wet grinding, enzymatic treatment, ohmic heating, aqueous extraction and centrifugation. The effect of ohmic heating parameters particularly electric field strength (EFS), end point temperature (EPT) and holding time (HT) on aqueous oil extraction procedure were investigated. Three levels of electric field strength (i.e., OH450V, OH550V and OH650V), three levels of end point temperature (i.e., 75, 85 and 95 °C) and three levels of holding time (i.e., 0, 5 and 10 min.) were taken as independent variables utilizing full factorial design. Percentage oil recovery from rice bran by EAEP alone and EAEP combined with ohmic heating had been 71 % and 73.59 % to 82 % respectively. The maximum oil recovery (82 %) was acquired when the sample was heated and maintained at 95 °C the usage of electric field strength of OH650V for a holding time of 10 min. The free fatty acid (FFA) of the extracted oil (i.e. in range of 1.89 to 2.24 %) was within the adequate limit of 3 % (oleic acid) and 0.5–3 % recommended respectively with the aid of PFA and BIS.
