Abstract A microwave oven with interlayer was designed for the problem of heating heterogeneity in microwave reactor. The multi-physics simulation method was used to explore the influence of waveguide position and interlayer thickness on heating efficiency and heating uniformity. The results show that the waveguide position can generally achieve higher heating efficiency under the liquid level of the material, but the heating uniformity is poor; and the interlayer can effectively improve the heating uniformity of the reactor and, in some cases, increase the heating efficiency. The response surface methodology (RSM) was used and the maximum heating efficiency of the optimized up to 99.19%, the waveguide height with the best heating uniformity is 389.74 mm, and the interlayer thickness is 30.09 mm.
