Nigeria is known for its annual production of over 265,000 tonnes / year of palm. Palm dehulling has been done manually using machete. Due to the difficulties involved in manual palm dehulling, it is necessary to mechanize the work by developing an indigenous palm shell peeling machine. This machine consists of spikes, chain drive, gears, electric motors, bearings, shafts, reduction gears and sprockets. The machines performed best with local varieties of palm with an average water content of 5.08% (db), giving average mechanical capacity and percentage throughput of 175 coconuts / h and 84%, respectively.
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.
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.
Drying is a common method for preserving apples. The effect of slice size on the drying rate and drying time of apples (Malus Domestica) was observed. Experiments were performed with slice sizes of 2,4,6 cm. The drying characteristics were examined by drying at 50 ° C for 720 minutes using a temperature cabinet dryer. During the critical drying time, total mass, drying rate, moisture content and moisture ratio were monitored. Using SPSS software, the effect of size on drying time was clarified. The results showed that the drying time decreased with slice size.
The existing area of vegetable planting in India is declining and cannot meet demand due to lack of mechanization. Labor costs associated with sowing and transplanting operations in vegetable planting are very high. Therefore, mechanization in sowing is important for increasing the area of vegetable planting. In this regard, a precision multi-variety transplanter for onion cultivation was evaluated for the selected onion crop, the local sowing variety Punjab Naroyawas. The sowing interval was adjusted to 0.02x0.75 m in the laboratory. A 1.25 m wide floor was created by a rotary cultivator and bedformer, and the average fuel consumption was 6.93 and 7.01 lh -1 for cultivated and non-cultivated soils, respectively. Four lines of onions were sown on each bed using a pneumatic transplanter. Average speed 3. 36Km.H -1, average fuel consumption 2.65Lh -1, average RTR spacing, 20.42cm, the average depth of the seed 2 cm, the average PTP spacing 7.86Cm, average field amount 0. 17Ha.H - It was 1. The mean observation index (PI) of the transplanter was 4.52%. Mean bulbs weight and yield of onion seed by pneumatic precision-mix transplantation machine, 57.45G and 9,562kg. acre relative grafting method -1 and 57.86g and 10,515Kg. Acre -1 was. The cost and time savings of the pneumatic precision high-mix transplanter were 55.12% and 98.53% compared to the transplantation method. The profit-cost ratios for onion sowing by the pneumatic precision high-mix transplanter and the manual transplantation method were 5.11: 1 and 2.62: 1, respectively.
