Simulation And Validation Of Radio Frequency Heating Of Shell Eggs, Soon Kiat Lau
Simulation And Validation Of Radio Frequency Heating Of Shell Eggs, Soon Kiat Lau
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Finite element models were developed with the purpose of finding an optimal radio frequency (RF) heating setup for pasteurizing shell eggs. Material properties of the yolk, albumen, and shell were measured and fitted into equations that were used as inputs for the model. When the egg was heated by itself, heating tend to be focused at the air cell to result in a “coagulation ring.” The focused heating near the air cell of the egg prevented satisfactory pasteurization of the egg, but deeper analysis of the simulation results offered a new perspective on how non-uniform RF heating could occur in …
Investigation Of Rf Curing Parameters In Resin Infusion Molding, Christopher K. Love
Investigation Of Rf Curing Parameters In Resin Infusion Molding, Christopher K. Love
Theses and Dissertations
The purpose of this study is to investigate RF or Radio Frequency energy as a viable alternative to traditional heating methods for the purpose of curing resins used in resin infusion molding, a molding system for polymeric composites. Traditional heating/curing methods include technologies such as room temperature, oven, microwave, infrared, and ultraviolet. Although RF curing provides far more advantages than disadvantages, its implementation into a manufacturing process can be challenging. Specifically, three critical elements must be present in order for RF to function in a manner that is profitable to the manufacturer. Those elements are: (1) the proper generator (voltage …
