Diseño y simulación de un autoclave para la esterilización de alimentos enlatados

The research project is based on the design and simulation of an autoclave for the sterilization of canned foods. An autoclave with discontinuous system was selected since they are the most used in the food industry. The design of the pressure vessel was carried out under the criteria of the ASME Section VIII Division 1 code, which provides the necessary information for the calculation of the design pressure, optimum thickness, materials, maximum stresses, welding efficiency. AISI 304 stainless steel was selected to avoid corrosion with a maximum allowable stress of 107000 kPa (15519 psi), as indicated in the ASME Section II Part D code. The operating pressure was determined to be 15 psi, while the design pressure is 45 psi. Obtaining a thickness of 5 mm for the cylindrical body and head of the autoclave. Through the SolidWorks software, the autoclave was modeled to perform the computational simulation with the use of the ANSYS DISCOVERY LIVE software, in which the physical properties of the fluid at the inlet and outlet of the pressure vessel are added, allowing to observe the behavior of the fluid and the heat transfer by convection between the steam and the cans inside the autoclave, in order to analyze the correct distribution, temperature and pressure of the steam according to the established times for each stage of the sterilization process. Obtaining favorable results in the multiphysics simulation.
