The 6-type flash dryer ordered by Hebei customers has been shipped on schedule. The company is mainly engaged in the manufacturing and sales of chemical products (excluding hazardous chemicals), pesticides (except highly toxic pesticides), fertilizers, and agricultural and sideline products.
Working principle of flash dryer:
◆ The air blower cuts the heated air from the bottom of the dryer into the mixing and crushing drying chamber at a suitable spray speed. The material that enters the host through the quantitative feeder produces strong shearing, floating, and rotating effects. The material is subjected to centrifugation and shearing. Cut, collide, and rub to be micronized, and water evaporates quickly. In the lower part of the dryer, the larger and wetter particle clusters are forced to be dispersed and broken under the shearing action of the stirring blade. The particles with lower moisture content and smaller particle size are entrained by the rotating airflow to rise, and are further dried during the ascent. Because the gas-solid two phases are rotating, the inertia of the solid phase is greater than that of the gas phase. The relative speed between the solid and gas phases is larger, which enhances the mass and heat transfer between the two phases. The dried material is collected by a cyclone or a bag filter, and the exhaust gas is passed through an induced draft fan. Discharge (or discharge after washing and cooling and condensing).
Features of flash dryer:
◆ This model is suitable for large-scale continuous drying of powder, granular and filter cake-like materials with high moisture content.
◆ Set up a variety of feeding devices to choose from, the feeding is continuous and stable, and the process is not easy to cause bridging.
◆ The bottom of the dryer can be equipped with a cooling device as required to avoid the phenomenon of bonding and carbonization of the material in the high temperature area at the bottom.
◆ The special air seal and bearing cooling device effectively extend the service life of the transmission part.
◆ The secondary heating and drying method can be designed according to the requirements to effectively extend the drying residence time and reduce the discharge moisture.
◆ The drying chamber can be equipped with a grading ring and a swirling plate, so that the fineness and final moisture of the material can be adjusted appropriately.
◆ High circumferential air velocity in the drying chamber, spiraling up and drying along the peripheral wall of the main machine, which not only reduces the height of the main machine, prolongs the drying residence time, but also has a certain wall sweeping effect.
