Working principle of SXG series fast rotary flash dryer:
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 shearing, blowing, and rotating effects on the material. As a result, the material is subjected to centrifugation, shearing, 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 by the agitator, while particles with lower moisture content and smaller particle size are carried up by the rotating airflow and further dried during the upward process. 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.
Product features of SXG series fast rotary flash dryer
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. Therefore, the production intensity of this machine is high.
The dry gas enters the bottom of the dryer, generating a strong rotating airflow, which has a strong flushing effect on the material on the wall and eliminates 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 high efficiency, speed, small equipment, and large production.
The upper part of the drying chamber is equipped with ceramic analyzer rings and swirl blades, which can control the particle size and humidity of the outlet materials to meet the requirements of different final moisture particle sizes of the materials.
