| Abstract | ||
| Seven sequence processing operations were conducted in a private commercial poultry slaughterhouse in order to determine the effects of the variations in the slaughterhouse operation capacity, and in the processed live bird weight, on the energy being consumed, under Egyptian conditions. The energy types used in the processing operations were electrical, gas fuel, and human energy. The respective proportions of these energy forms of the total consumed energy are varied automatically in accordance to the slaughterhouse production capacity. The energy accounting process were proceeded for the specific energy consumption (SEC) in reception, and hanging up; killing and bleeding; scalding; defeathering; evisceration and washing ; chilling ;and packing departments(sections) of the slaughterhouse.The gained results of the present study indicated that:-*Sensible decreases of about 49.4 and 46.4%, in the energy use per kg of poultry product (ready-to-cook), were happened as increasing the slaughter operation capacity from 1000 to 3000 and from 3000 to 6000 respectively. The results also indicated that increasing the average processed live bird weight, from 1.6 to 1.8 Kg and from 1.8 to 2.0 Kg caused reductions in the energy use per kg of product by about 19.7 and 25.3% respectively.* The average specific electrical energy consumptions represents 73.8%, of total specific energy consumption in the investigated slaughterhouse, followed by the average specific thermal energy (gas fuel energy), and human energy which represent 23.43%, and 2.77%, respectively .*Analysis the energy consumption data in the seven defined slaughtering processing operations revealed that the scalding and defeathering are the most consumptive operations, requiring 29.53%, and 36.79% of all energy consumed in processing operations, respectively. Other operations consuming energy in the following order: - Hanging (1.07 %), slaughtering (1.26 %), evisceration (7.91 %), chilling (18.08 %) and packing (5.37 %). | ||
