Microwave drying equipment Application in paper products industry. Microwave has the characteristics of fast heating, uniformity, energy saving, safety, no breakage, no deformation, continuous production, greatly improving working conditions, and has been widely used in paper products and other industries.

Paper products have poor thermal conductivity, and the surface moisture is not removed in time, which will produce certain stress, causing dry paper products to bend and deform.

The traditional hot air drying furnace needs time because it is heated and dried by heat conduction. The surface moisture is dried first, and the dried paper products will be bent and deformed. The microwave drying equipment heats the materials inside and outside at the same time, making paper products produce a series of physicochemical processes such as rapid heating and expansion. However, in order to achieve the purpose of heating, the surface of the materials directly contacts with the air, and its central temperature is slightly higher than the surface temperature, which is conducive to the diffusion and volatilization of water from inside to outside.

The utility model has the advantages of uniform microwave heating, short drying cycle and continuous automatic production. In the process of processing paper products, the process is very important. According to the material variety (such as round paper tube, square paper tube, cardboard, etc.) and moisture content, balance the evaporation rate of water on the surface of the material and the internal diffusion rate, and the heating temperature should not be too high.
