With the further expansion and implementation of similar smoking bans around the world, research on heat-not-burn tobacco is considered to be one of the most important research areas for the transformation and upgrading of tobacco companies. At present, the working principles of the heat-not-burn tobacco heating equipment currently on the market or under research are mainly categorizeded into three types: carbon heating type, resistance heating type, and induction heating type. High-cost issue. Radiofrequency heating is a method of wireless energy transmission, which has the advantages of fast heating speed, high efficiency, non-contact, and so on, and has a wide application prospect in tobacco heating. However, the research and application of radiofrequency heating for tobacco heating is very limited at present. Therefore, it is significant to conduct related research on radiofrequency heating-not-burn tobacco. Based on the finite element simulation software COMSOL Multiphysics, this paper starts with the three-dimensional simulation model of bipolar plate RF heating tobacco and describes the simulation settings in detail. The solid heat transfer module simulates the heating results of the tobacco matrix from the transient and steady-state aspects, analyzes the simulation results, and obtains the temperature rise law of the tobacco matrix under different conditions, which provides a basis for subsequent equipment development. theoretical basis.
