Given the physical design of the system, volume
capacity and volumetric flow rates, the application of microwave energy for the pasteurization of apple cider is a feasible thermal process, especially with increased power. One major factor in designing a continuous-flow microwave pasteurization system is to insure the fluid is obtaining uniform thermal energy. The large cavity oven showed to produce uniform heating throughout the cavity and the use of helical coils would narrow the residence time distribution as indicated by the large Dean numbers. A significant improvement on the efficiency of the process would be to insulate the coils within the cavity. Research
