A portable apparatus for separating the expended husks from bird seed mixtures after the bird has shelled the seeds and left the husks among the seeds has been designed. It includes a hopper, rectangular case divided in two parts (one for receiving seeds and other collecting un-seed materials) and air supply means. The air stream agitates the mixture and floats the husks and fine dust up wardly for collection in the husk receiver while the air exhausts through holes at the opposite side. The experiments included four cleaning air speeds (2.5, 3.0, 3.5 and 4.0 m/s), four baffle angles (35, 40, 45 and 50°), two fiberglass baffles (with or without rubber covered) and two seed samples (before and after feeding). Cleaning efficiency and seed losses were measured. Results showed that, the maximum value of cleaning efficiency (98.7 %) for seed mixture before feeding was achieved at cleaning air speed of 4.0 m/s, baffle angle of 35° and baffle without rubber. The minimum value of seed losses (0.3 %) for seed mixture after feeding was achieved at cleaning air speed of 2.5 m/s, baffle angle of 50° and baffle with rubber. It is recommended to use the cleaning device at cleaning air speed of 4.0 m/s, baffle angle of 35°, baffle without rubber to increase the cleaning efficiency and use it at cleaning air speed of 2.5 m/s, baffle angle of 50°, baffle with rubber to lessen seed losses.
This research aimed to develop and evaluate flipping and sterilization machine "FSM" for poultry litter. The developed was done on the base of rotary blades by adding a steam sterilization unit. The "FSM" attached with sterilization unit was an electrical heating wire. On both side of heater case a two fans were fixed for pumping hot air to poultry litter during flipping process. To avoid a dust and impurities that can be found during operating a flipping unit a filtration system was identified. Evaluation "FSM" performance were done at laying hens farm under fluctuates experiments that included; blades revolutions "Br" (240, 480 and 960 rpm), blades depths "Bd" (5, 8 and 10 cm) and litter life periods (6, 8 and 10 months) per using and un-using sterilization process (St). The measurements included litter properties as bulk density "D", clodsize distribution "CD", mean weight diameter "MWD" and total bacterial counts (BC) CFU/g. All above parameters conducted less than three litter life from cycle period (6, 8 and 10 months). The results showed that using "FSM" reduced bulk density to 0.3 g/cm 3 and the maximum percentage of particle litter size distributions of "CD" recorded 60.3% with "MWD" of < 2cm. and reducing microbial count to 105.7 CFU/g under "FSM" operating depth of 5 cm with rotating shares of 960 rpm at litter life of 10 months from cycle period and using sterilization unit.
This study was conducted to compare between the new integrated quail rearing unit with egg hatching sub-unit, and common egg incubator with traditional rearing system for (black Japanese quail and white jumbo quail) at two eggs hatching positions (vertical position with small end up and down). An integrated unit provided with upper egg incubator and furnished rearing battery cage located lower of it. The chicks were reared for 40 days of age in traditional litter floor and in furnished battery cage. The evaluation include the percentage of hatchability, chick weight, growth performance and mortality number of quail. The result indicated that the new incubation unit was able to maintain a high hatching percentage of 78.53 % for eggs of white jumbo quail with vertical egg position with small end down in average of hatching period 17 days. Chicks were growing in normal weight at 6.99 and 8.19 gram and did not suffer from any disability for black Japanese and white jumbo quail eggs, respectively and with vertical position with small end up. At different time intervals the growth performance of quail didn't show significant difference among the treatment viz. common commercial egg incubator and new incubation sub-unit. The mortality number at the first days increases for quails hatched in common commercial egg incubator. The same capacity attached egg incubator saved about 81.25 % of the total cost compared to the common commercial egg incubator, so it is recommended to use the integrated unit for incubating and rearing quail
A small grading machine was developed, fabricated and evaluated technically and economically acts by using cylinder system of rod for grading system for crops such as Baladi eggplant variety be used in small horticultural holdings, small grading stations and small factories. Series of experiments were carried out to study effect of some parameters such as rotary speed of grading unit (0.31; 0.41; 0.59) m/sec and slope angle of grading unit (0.0; 1.0; 2.0; 3.0 deg.) on grading machine capacity (ton/h), grading efficiency (%), mechanical damage of eggplant (%), specific energy consumption (kW. h/ton) and total operation cost (LE / ton) to evaluate the grading prototype. The optimum results were obtained at rotary speed 0.41 m/sec and grading slope angle 2.0 degree. At above variables the grading efficiency recorded 84.6 %, damage index of 2.71%, specific energy consumption of 0.32 kW. h/ton and total productivity cost for one ton was 5.62 LE / ton for Baladi eggplant variety.
