ABSTRACT: Ohmic
Heating (OH) is one of the emerging thermal technologies used in food
processing which can produce rapid and uniform heating with close to 100%
energy transfer efficiency. Although mathematical modelling for OH processes has been studied by many researchers in
recent years, systematic simulations of OH have not been developed for
model-based control of the processes. In this paper, mathematical model for a Colinear Ohmic Heater is presented,
analyzed, and studied based on the selected configuration. A numerical solution
for the mathematical equations has been defined and proposed. MATLAB/Simulink
model is hence developed and validated against the available data. Simulation
results have shown that MATLAB/Simulink
model can produce robust outputs at low computational costs with an accuracy of
up to 99.6% in comparison to the analytical solution. This model can be used in
further studies for analysis of the OH processes and development of advanced
controllers.
