Design and manufacturing an electromagnetic hybrid retort system

In todays's world, due to population growth and bus work pace, the demand for ready to eat food is stedily increasing. In the absence of any preservation treatment, food deteriorate rapidly, posing significant risks to human health. Ready- to- eat products must undergo the necessary heat treatment to ensure a long shelf life and to be suitable for consumption in the long term from a human health perspective. Thermal treatments aimed at food preservation are carried out using retort technology. Today, retort systems, which are extensively employed in the food sector, are generally high energy consuming systemse that utilize resources such as solid fuel and fossil fuel. During the production stages in the food industry, which also involve retort systems, a high amount of energy is consumed. Therefore, retort systems contribute significantly to carbon emissions. In the study, an electrically operated retort system was designed and manufactured as an alternative to the fossil fuel consumption required for generating the working fluid steam or hot water in traditionally used pressurized retort systems. In the first stage of this research, mathematical model development studies and analyses conducted simultaneously in Comsol and Ansys/Maxwell. The magnetic field distribution and temperature distribution within the system and the product were investigated. In mathematical model development studies, the frequency, ampere value, coil geometry and system dimensions to be used within the system were tested at different values and the optimum system values were obtained. The frequency values were compared at 10, 25 and 100 levels, and the optimal frequency was determined to be 25. The coil geometry has been tested and compared in both circular and rectangular analyses. The outcomes of the modeling research were found to be in close agreement. In the system, canned containing prodcuts to undergo thermal treatment were designed in quantities of 1,3 and 4 and their temperature distributions were examined. In the design containing 4 cans, the temperature was distributed homogeneously, heat exchange occured between the cans, and uniform heating was achieved. The effect of different thickness values on the system was examined as a result of mathematical modelling for polymer body material of FR4 and production was completed within the parameters of mathematical model development studies. In the context of this thesis, the design of a retort system based on the principle of working with electric has been completed abd production has been carried out. An first experiment was carried out to thermal treatment of the canned within the system, and the target surface temperature of 120 ° C was achieved.
