Working principle of WYH series rotary flash dryer:
& nbsp; & nbsp;Hot air enters the mixing and crushing drying chamber from the bottom of the dryer at a suitable spraying speed through the inlet pipe, generating strong shear, blowing, and rotating effects on the material. As a result, the material is subjected to centrifugation, shear, collision, and friction, and is atomized, enhancing mass and heat transfer. At the bottom of the dryer, larger and wetter particle clusters are mechanically crushed under the action of the agitator. Particles with lower moisture content and smaller particle size are carried up by the rotating airflow and further dried during the upward process.
& nbsp; Due to the rotating flow of gas-solid phases, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity between the solid and gas phases is higher, which enhances the mass and heat transfer between the two phases. Therefore, the production intensity of this machine is high. WYH series rotary flash dryer.
Flash drying characteristics:
Due to the material being subjected to centrifugation, shearing, collision, and friction, it becomes highly dispersed and the relative velocity between solid and gas phases is high, which enhances mass and heat transfer and increases the production intensity of the machine.
The dry gas enters the bottom of the dryer, generating a strong rotating airflow that has a strong flushing effect on the material on the wall, eliminating wall sticking.
In the high-temperature zone at the bottom of the dryer, thermosensitive materials do not come into direct contact with the hot surface and are equipped with special devices to solve the problem of coking and discoloration of thermosensitive materials.
Due to the high circumferential gas velocity in the drying chamber, the material residence time is short, achieving fast, small equipment, and large production.
Installing ceramic rings and swirl plates on the upper part of the drying chamber can control the particle size and humidity of the outlet materials to meet the requirements of different final moisture particle sizes for different materials.
