Abstract [en]
A pilot-scale process for continuous in-flow microwave heating of pumpable foods was designed, built and evaluated for heat treatment of high-concentrated particulate foods at temperatures up to 135°C and at the microwave frequency 2450 MHz. In this work, the temperature uniformity of a particulate model soup after microwave heating is evaluated for selected goal temperatures and holding times, and the heating up time to goal temperature is investigated. Furthermore, choice of radial dimensions of the tube is discussed, as well as strategies for achieving an improved microwave heating uniformity of the product, based on calculated radial temperature profile and electromagnetic field distribution.
