Simulation Study of a Helical Treatment Chamber for PEF Pasteurization
Abstract
Pulsed electric field (PEF) is a developing non-thermal way for the treatment of fruit juices. Due to the low consumption of energy in this treatment, the temperature of the sample liquid remains low. So, it helps to preserve the taste as well as the nutritional value of the liquid food. However, non-uniform distribution of electric field is a common problem inside the treatment chambers. The laminar flow inside the treatment chamber is a reason for treatment inhomogeneity in the chambers. The helical shape is a motivation due to its favorable features, including the tabular flow of the liquid inside the chamber. Numerical simulation is a way to analyze the distribution of the electric field before designing any treatment chamber. The simulation results indicate a homogenous electric field strength in the helical treatment chamber. This study provides new insights into industrial-scale set-up by using multiple helical chambers in a continuous flow PEF pasteurization.
