Abstract

ABSTRACTEnergy use for a poultry broiler processing plant was analyzed using available monthly utility bill information, utility-provided 15-minute interval data, and short-term 30-second submetered data at the unit operation level. Energy intensities were determined in terms of the whole plant and unit operations, and both compared to three broiler processing plants that operated in the late 1970s. It was found that secondary utilities, including water chilling, ice making, and compressed air, are the largest energy consumers in the process, followed by offal, receiving, killing and picking (RKP) and evisceration. On a total energy (MMBtu) basis, natural gas usage for steam generation by boilers was higher than site electricity consumption. Overall, the total annual energy intensity was found to be 2.46 MMBtu/1000 head of broilers processed. The largest opportunities for reducing energy intensity exist in the process refrigeration and hot water generation systems. Finally, it was concluded that measuring...
