DWP type belt dryer belt drying type jet stream, hot air from a slit or hole beam up or down simultaneously sprayed material on the belt, because the jet gas velocity up to 15m / s or more, so the convective heat transfer membrane electrode thin, heat transfer coefficient, and fast drying. The equipment used for gas-impermeable material class, the upper jet stream still returns above, below exhausts still returns the following, and then participating in the loop. Applications: DWP type jet stream belt dryer is mainly used for fiberboard, gypsum board, carton board, pulp molding, coating and drying, also applies to the sheet material and dried some special materials. DWP type jet stream type belt drying, hot air from a slit or hole beam up or down simultaneously sprayed material on the belt, because the jet gas velocity up to 15m / s or more, so the spread of thin film heat, heat transfer coefficient of big, fast drying. The equipment used for gas-impermeable material class, the upper jet stream still returns above, below exhausts still returns the following, and then participating in the loop. An air flow of breathable material with strong penetration and diffusion inside the material. Heat source can be steam, electricity, stove and fuel smoke ventilation and so on.
