Important Equations Flash Freezing of Chicken Theory Simulations Objectives Why is the project being carried out? Conclusions • Achieve a cold box type refrigeration system, which allows the freezing of chickens in the specified time ( 16 hours) • Understand the process of freezing chickens in cold boxes • Optimize a current cold box model, prioritizing the reduction of freezing time • Obtain a successful simulation of an optimized cold box model • This project is carried out due to the food industry, specifically raw chickens, which must be refrigerated and frozen for prolonged storage Due to this situation and the FDA regulations, the duels of this type of business try to freeze their product in the stipulated time of 24 hours, but to increase production and sales, it is desired that the 40 lb of chicken that is stored per cold box, they can freeze in 16 hours H eat Transfer J uan Jose Erazo, Jacqueline Lincango , Jose Bilbao, Jassir Chalá • Heat transfer : exchange of heat in a system • Three important phases : • Conduction • Convection • Radiation • Thermodynamics : • Refrigeration cycle : the extraction of energy from a system to reach a suitable temperature • Four main stages : • Expansion • Evaporator • Compressor • Condensation • it was possible to obtain a cold box model optimized both analytically and in simulation • It is concluded that the pressure in the system can achieve a faster freezing without a large decrease in temperature Bilbiography • Bergman, T L , Incropera , F P , DeWitt , D P , & Lavine , A S ( 2011 ) Fundamentals of heat and mass transfer John Wiley & Sons • Ali, S , Zhang, W , Rajput, N , Khan, M A , Li, C B , & Zhou, G H ( 2015 ) Effect of multiple freeze – thaw cycles on the quality of chicken breast meat Food Chemistry , 173 , 808 - 814
