Abstract

The invention belongs to the field of microwave heating application technology and discloses a high efficiency microwave feed excitation system for a heating cavity. The system includes a microwave excitation source. An output port of the microwave excitation source is connected to a first port of a circulator through a first connection waveguide. A second port of the circulator is connected with the heating cavity through connecting with a second connection waveguide. A third port of the circulator is connected with one end of a chamfer curved waveguide. The other end of the chamfer curved waveguide is connected with one end of a polarization reversing waveguide. The other end of the polarization reversing waveguide is connected with the heating cavity through connecting with a third connection waveguide. According to the invention, the efficiency of energy feed from the microwave excitation source to the heating cavity and the efficiency of microwave energy absorption of a target are improved substantially.

Description

technical field [0001] The invention belongs to the technical field of microwave heating applications, and in particular relates to a high-efficiency microwave heating cavity feed excitation system. Background technique [0002] Microwave heating is a high-efficiency and energy-saving heating method. The basic principle is to irradiate the target with high-power microwaves, so that the irradiated target generates an oscillating current from the inside to the outside, and generates heat to achieve heating. Because the microwave heating system is non-polluting, high in efficiency, fast in heating speed, and can simultaneously realize the sterilization of the target, it is widely used in various aspects such as grain drying heating, feed processing heating, and food production heating. However, it should be emphasized that in the field of high-power microwave heating involving industrial production, there are still some problems: (1) When the cavity is directly excited by the w...
