Problems solved by technology

[0002] Most of the existing microwave heating equipment is static heating, and it is impossible to realize the tunnel kiln with continuous cycle and non-stop work. For the new structure, it needs a lot of structural innovation and improvement. Direction, heating, and then complete unloading, such a cyclical process requires a new structure to be designed for a series of problems such as its specific kiln car, track, and walking mechanism, and it also needs to be adapted to the new microwave heating and drying form.

[0003] Moreover, the traditional microwave heating cavity structure adopts a built-in thermal insulation structure. Although it can achieve good thermal insulation effect, long service life of the reflective surface of the resonant cavity, low working temperature and low failure rate, it is mainly used in microwaves with low magnetic flux density. In heating equipment, the requirements for the purity of the refractory material of the insulation layer are high, and the insulation layer cannot contain microwave-absorbing components, but conventional materials contain such microwave-absorbing components, so the built-in insulation structure cannot be used in high-density microwave equipment
