Manufacturing and testing the performance of prototype for grading of dates

Paper ID- AMA-10-04-2021-10501

The specifications of locally produced orchard crop sorters are determined without the use of appropriate methods that take into account the graded materials, and design factors also affect the grading efficiency. A study was conducted on the possibility of using a prototype of a rotating drum screen sorter for grading data to determine optimal values that affect design factors for grading efficiency. A rotating screen sorter with a 244x84 cm skeleton was constructed and tested during 2016 at a regional factory located in the city of Kafr Eleheikh. Maximizing the classification efficiency of the sorter represents a predictive response as a dependent variable. Box-Behnken is a three-factor, three-level method using the response surface methodology to determine the rotation speed, inclination angle, and supply speed on the rating efficiency. It is necessary to establish an interaction quadratic polynomial model generated by statistical design. Three different varieties representing date palms known in Egypt called Bartamuda, Grandilla and Shamiyya were selected and graded after studying their physical properties. The model created predicts rotational speed, tilt angle and feed rate levels, with 26.004 rpm, 4.720 degrees and 1 kg / min optimal for the maximum response of grading efficiency (61.669%) for Bartamuda species, respectively. For the maximum response of grading efficiency (77.327%) for Gandika varieties, 26.468 rpm, 1 degree and 1 kg / min were optimal, respectively, and grading efficiency (40.988%) for Shamiyya varieties.) Was optimal at 26.003 rpm, 1.085 degrees and 5 kg / min, respectively. These apparent differences in efficiency for each variety were entrusted with studying the correlation between the physical properties of these varieties and the maximal grading, and principal component analysis was performed. The results show that physical properties such as fruit thickness and spheroidity have the greatest negative effect on optimized grading efficiency. Properties such as bulk density have been shown to have a positive effect. This study dealt with all the factors that affect the efficiency of the rotating screen sorter for a certain number of days.

Design and development of thresher for onion umbels (Allium Cepa Variety Aggregatum L.)

Paper ID- AMA-10-04-2021-10500

Freshly harvested sun-dried onions were peeled on a farm-level peeler to increase seed damage and overcome the heavy labor of traditional peeling methods, which affect germination and vitality factors. High quality seeds can be produced through effective peeling and separation processes. The peeling machine basically consists of a pre-peeling machine, a peeling machine and a blower. The PEG toothed pre-peeler separates the florets from the hard onion head and then sends them to the peeler for the separation of seeds from the florets. The raps bar type peeler separated seeds from floret and good seeds from dust and skin material. The performance of the peeler was evaluated for florette peeling efficiency at different feed rates, ambient and wash air rates, good seed rate collected, seed loss rate, and seed loss. It was concluded from the evaluation that a 6 mm concave gap gives good results at a supply rate of 100 ± 5 kg / h, an ambient speed of 7 m / s, and a washing air rate of 4.5 m / s. The peeler recorded maximum peeling efficiency, good seed rate collected, seed damage and cleaning efficiency of 99.85, 97.70, 1.75 and 96.46%, respectively.
