The performance of paddy and rice separator was theoretically and experimentally investigated as a function of change in separator sieve angle, paddy moisture content and feeding ratios. The separator performance was evaluated in terms of separator productivity, crack percentage, separator efficiency and energy requirements. The theoretical analyses reveal that the optimum sieve speed of 0.5 m/sec. (200 rpm) is recommended to prevent riding of material on the sieve surface. The experimental results reveal that the separator performance was in the optimum region under the following conditions: • Sieve angle of 15 deg.
The experimental work was held in commercial broiler house at Babil village, Menofia Governorate, latitude and longitude angles are 30. 67°N and 30.98°E, respectively) during winter season of 2015 in order to evaluate the performance of manufactured heating system and its effect on indoor air temperature and energy requirements. The indoor air temperature above the floor surface, indoor air relative humidity, fuel consumption, heat energy addition and specific heating power for every cubic meter of house volume were measured and specific fuel consumption also. Broilers performance evaluation was also determined in terms of live body mass. The obtained results showed that using manufactured heater in heating broiler house the weekly average indoor air temperature ranged between 31.61 to 23.26 ºC at first and fifth week respectively. Whereas, the indoor relative humidity ranged between 26.15 to 52.48% at the same ages. The average heat energy addition to the house was 63.28 kW throughout the bird's life and specific heating power was 148.4 W/m 3 at the first week and reduced to be 37.07 W/m 3 at fifth week. Heating energy requirements decreased from 422.59 kJ/h.kg at the first week of age until reached to 19.45 kJ/h.kg at fifth week of age where the average broilers body mass was 2.2 kg.
INTRODUCUTIONeating broiler houses for provide a better thermal environment is important in broiler houses for maximizing broilers meat production especially during the first seven to ten days of the chick's life. Because, in the first week their body temperature, metabolic rate, body mass to surface area ratio, insulation from feathering and thermoregulatory ability are all relativity low .
The main objective of this research was to determine the amount of oil fish were extracted from fish west resulted from butchering, cutting and splitting processes before salmon smoking by using cold pressing `methods. The amount and the characteristics of extracted of oil were tested at Regional Centre for food and feed the USDA Agricultural Research Center laboratory. The samples were used from fresh Salmon waste about 1000g from each of the (head, skin, viscera, backbone, frames and cuts off). This waste recorded more than 22% of the total mass from salmon fish with used modern extract machine. in this experiment the results revealed the fresh salmon waste have more than 16 % of oil fish per one kg of salmon waste. The oil weight from Salmon waste for (head, skin, viscera, backbone, frames and cuts off). was increased with pressing time increase as well as oil productivity increased. The optimum conditions at pressing time was 200 min, for all salmon waste components . Oil productivity fluctuated according to waste sources was 190, 210, 86, 188, 178 and 90 g.oil/1000 g. by head, skin, off cuts , terming, , viscera , and backbone frames, Salmon by-products, oil productivity was ranged between 8.60 to 21.00% at constant pressure. High contents of functional EPA (20:5 ω 3) and DHA (22:6 ω 3) for oil fish
The transmission system of the combine cutting device was developed and manufactured from local material to be suitable for the harvesting operation under Egyptian conditions. Performance evaluation of the combine before and after development during the harvesting operation of rice crop was carried out in terms of grain losses, field capacity , field efficiency, fuel consumption, required power, energy, wearing rate, wearing resistance and cost requirements. The combine performance was studied as a function of change in combine forward speed and grain moisture content and operating time. The results were obtained to gave maximum field capacity, field efficiency, wearing resistance and minimum energy, power, fuel consumption wearing rate, and cost requirements for the two systems of the combine cutting device before and after development as following: 1-It is recommended to used the developed combine. 2-The combine forward speed of about 3.5 km/h. 3-The grain moisture content about 23%.
