What is the industrial application range of the flash dryer?
The flash dryer is a vertical fluidized bed dryer with a rotary pulverizing device, which can simultaneously perform pulverization, drying, grading and the like of materials. The main body of the device is a cylindrical drying chamber, which is composed of a pulverizing fluidized section at the bottom, a central drying section, and a top grading section. The bottom pulverizing section is equipped with a stirrer to drive the hot air entering the drying chamber from the distribution chamber to generate a high-speed rotating airflow to form a fluidized bed; at the same time, the material is strongly stirred and pulverized, the mass transfer heat transfer is enhanced, and the material is accelerated. Drying speed. A screw feeder is arranged in the drying section, and the feeder is dragged by the speed regulating motor, and the rotation speed is adjusted by the frequency converter. The top grading section has a grading ring that selects the diameter of the grading ring according to the granularity requirements of the product. The dried fines of the material can be sent to the cyclone or bag filter for collection with the gas stream.
Â The flash dryer is ideal for handling dispersible filter cakes and viscous paste materials. Zui has long been used in the dye industry. After years of application practice, a variety of models have been developed and a series of products have been formed. According to the way that different materials are connected in series with other drying equipment, the application range of the equipment is increased. At present, flash dryers have been widely used in dyes, pesticides, and industrial production such as organic chemicals and inorganic chemicals.
