For the prototype chamber, experiments were carried out taking into account four different configurations of magnetron operation (top only, bottom only, both and both with a MW mixer). Fugures below shows the temperature profiles for each analysed configuration and photos of food samples after the process.
Food product temperature profiles for MW heating in the prototype chamber with operation of (a) the lower magnetron, (b) the upper magnetron, (c) both magnetrons and (d) both magnetrons with the MW mixer
Appearance of food product samples after the MW heating process in a prototype chamber using: (a) the lower magnetron, (b) the upper magnetron, (c) both magnetrons and (d) both magnetrons with the MW mixer
