Background
The honeycomb ceramic is a novel ceramic product with a structure similar to a honeycomb shape, and the use of the honeycomb ceramic is more and more extensive. The honeycomb ceramics are composed of countless equal holes into various shapes, and have the characteristic of porous thin wall. A large amount of automatic equipment, such as an automatic forming machine or an automatic drying machine, is adopted for limiting the production of ceramic products, and the drying equipment adopting microwaves in the automatic drying process has the characteristics of high temperature controllability, good drying effect and energy conservation. The microwave drying method is completely different from the traditional drying method, and is a process of making the dried material become a heating body without heat conduction. However, due to the characteristic of the porous thin wall of the honeycomb ceramic, a large amount of heat can be generated inside the honeycomb ceramic in the drying process, so that the inside and the outside of the honeycomb ceramic are heated unevenly, local expansion is generated, and the forming of the honeycomb ceramic is influenced. Moreover, in the drying process, the water vapor generated in the honeycomb ceramic is difficult to volatilize, and the drying effect is also influenced, so that the water vapor generated in the drying process needs to be discharged in time.
