Under normal circumstances, when using a tray dryer for evaporative drying, other mechanical equipment will not be added for integrated operation, but other special circumstances are not excluded. For example, it is necessary to increase the continuous drying during the drying process of the tray dryer, and there is no continuous dryer equipped. At this time, you can equip the tray dryer with a fin heater , To achieve continuous drying of the dryer.
This kind of drying mechanical equipment is suitable for drying process with high evaporation intensity. On the basis of the basic configuration, a fin heater is added, and a small flow of hot air is introduced into the dryer to absorb the water vapor that escapes from the material during the drying process and prevent moisture from being on the top of the dryer and exhaust Condensation in the tube.
During drying, a heating medium is introduced into the hollow drying plate. The heating medium includes saturated steam, hot water and heat transfer oil. The heating medium enters from one end of the drying plate and exits from the other end. The dried materials fall from the last layer of the drying plate to the bottom layer of the shell, and are finally moved by the rake leaves to the discharge port for discharge. The moisture escapes from the material and is discharged from the moisture outlet provided on the top cover. The moisture of the vacuum type disc dryer is pumped out by the vacuum pump provided on the top cover.
The dry materials discharged from the bottom layer can be directly packaged. By adding finned heater, solvent recovery condenser, bag filter, dry material backmixing mechanism, induced draft fan and other auxiliary equipment, it can improve its drying production capacity. Dry paste and heat sensitive materials can be easily recovered Solvent, and can perform pyrolysis and reaction operations.
