Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola

Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    Title : DEVELOPMENT OF POWER OPERATED LEMON CUTTING MACHINE.
    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2020-12-12) Authors : WAGH, RANI SURESH.; Advisor : Mate, Dr. V. N.
    Abstract : Present work is entitled “Development of power operated lemon cutting machine”. The physical properties of lemon were studied and lemon cutting machine was developed and evaluated for performance. The major components of the machine include the feeding unit, cutting mechanism, frame, drive unit, electric motor and outlet tray. The machine is powered by 1 hp a single phase electric motor. The performance of the machine was evaluated for cutting of lemon into 4 pieces, at three feed rate 100 kg/h, 150 kg/h and 200 kg/h respectively at three motor speeds of 10 rpm, 25 rpm and 40rpm, respectively. The response parameters investigated were cutting efficiency and waste percentage. Two variable three level central composite rotatable design model of response surface methodology by using Design Expert Software was used to optimize machine parameter for better cutting efficiency and lower waste percentage. The length, width and thickness of lemon fruit was found out to be 32.18 mm, 29.39 mm and 30.55 mm respectively. The geometric mean diameter was 30.68 mm while sphericity was 0.9535 and aspect ratio was 1.09. True density and bulk density of lemons were 0.673 g/cc and 0.98 g/cc respectively. Moisture content was 93% (w.b) for lemon fruit while coefficient of friction static and dynamic was 0.63 and 0.57 respectively. Cutting force required to cut the lemon was found out to be 375 N. A feed rate 150 kg/h, motor speed of 25 rpm was found to favour the cutting efficiency of 97.12 % and waste percentage 2.88 %. The machine was therefore observed to perform best at the optimum operating speed of 25 rpm. The result of the study shows that the machine can dice satisfactorily.
