Acharya N. G. Ranga Agricultural University, Guntur (AP)

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    DEVELOPMENT AND EVALUATION OF MULTI SEATED AONLA SEED REMOVING MACHINE
    (ACHARYA N.G. RANGA AGRICULTURAL UNIVERSITY, GUNTUR, 2014) NAZMA HAFEEZA, SHAIK; BHASKARA RAO, D
    Indian goose berry (Emblica officinalis) popularly known as Aonla is one of the precious gift of nature to the mankind and considered as “wonder fruit for health”, for its inherent qualities. It is a vitamin C rich fruit. The raw fruit, due to its high acidic nature and astringent taste, it is unacceptable to consumers. The fruit offers great potential for processing it into quality products. Recently, a number of processed products of aonla such as candy, supari, RTS (ready to serve), nector, squash, pickle, juice, shreds, dried powder etc., are prepared from aonla fruits to improve their acceptability and exploit nutritional qualities, besides its use in ayurvedic formulations. For making candy, supari and any processed products of aonla, deseeding and segmenting is needed. These operations are being done by using hand tools which is time consuming and may require several workers to perform the operation and thus increase the operating cost. Therefore, in this study, a machine was developed to combine the process of deseeding and segmenting in one device. A power operated multi seated aonla seed removing machine was designed and developed for small scale processing, based on physical properties of aonla varieties namely, Chakaiya and NA-7. The moisture content of aonla cultivar viz., Chakaiya and NA-7 were 80.5 and 78.5%, respectively. The size, sphericity, aspect ratio, surface area, volume, density, pulp to seed ratio of cultivars Chakaiya and NA-7 were 36.33 and 32.95 mm; 95.8 and 94.7%; 90.84 and 88.23%; 4249.9 and 3601.8 mm²; 28.95 and 22.56 cm3; 1.06 and 1.07 g/cc and 21.14 and 15.77, respectively. The seed radial diameters of Chakaiya and NA-7 were 13.46 and 13.54 mm, respectively. The maximum diameter of seed was found as 13.88 mm, thus plunger diameter of 14 mm was considered. The seed (stone) weight of Chakaiya and NA-7 were 1.4 and 1.45 g, respectively. It was observed that the maximum force required for cutting the Chakaiya variety along the stem end side and apex end side was found to vary in between 8.4 to 9.9 kgf and 8.9 to 9.1 kgf, respectively. The maximum force required for cutting the NA-7 variety along the stem and apex end side was found to vary is between 8.6 to 11.8 kgf and 8.8 to 10.5 kgf, Name of the Author : NAZMA HAFEEZA SHAIK Title of the thesis : “DEVELOPMENT AND EVALUATION OF MULTI SEATED AONLA SEED REMOVING MACHINE” Degree to which it is submitted : Master of Technology Faculty : Agricultural Engineering Major field of study : PROCESSING AND FOOD ENGINEERING Major Advisor : Dr. D.BHASKARA RAO University : Acharya N.G Ranga Agricultural University Year of Submission : 2014 respectively. The machine consisted of a main frame, circular platform with fruit rests (6 Nos.), plungers (6 Nos.) with cutting blades, plunger reciprocating mechanism, worm and worm gear, belt drive and 1hp motor. The machine was operated at 9 rpm speed of worm gear with 14 mm diameter plunger. The machine has deseeding cum segmenting efficiency of 91.1 and 88.8% for Chakaiya and NA-7, respectively with effective capacity of about 84 kg/h for Chakaiya and 67.5 kg/h for NA-7 cultivar, and 2700 fruits/h for both the cultivars. The pulping efficiency, per cent fruit pulp, fruit juice wasted and per cent whole segmented fruit recovery were found as 86.1%, 7.7%, 6.0% and 84.4% for Chakaiya cultivar and 85.3%, 8.7%, 5.9% and 80.0% for NA-7 cultivar. The operating cost of the machine per kg is Re.0.38/- or Rs. 377.9/tonne. The cost of operation of machine for cutting 16.6 kg is Rs.6.25/- as compared to hand operated machine developed by earlier researchers was Rs.10.20/- for same production. The saving in cost was 38.7%. Products such as Chakaiya candy, NA-7 candy, Chakaiya supari and NA-7 supari were prepared from aonla fruits. Among these products, Chakaiya candy and NA-7 supari recorded the highest organoleptic score for taste (8.5 and 8.5) color (7.5 and 7.5) and overall acceptability (8.5 and 8.5). Hence, for candy preparation Chakaiya variety was considered to be more acceptable where as for supari preparation NA-7 variety was more preferred. Key words: Aonla fruit, Chakaiya and NA-7 cultivars, power operated multi seated machine aonla candy, aonla supari, plunger, worm gear, reciprocating mechanism, pulping efficiency, percent fruit pulp, sphericity, aspect ratio, pulp to seed ratio.
