Flash drying machine

rotateFlash drying machine：It is a new type of high-efficiency fluidized bed drying equipment developed by our company to overcome the low efficiency and high consumption of static drying. In the design process, the machine fully combines the characteristics of ordinary fluidized bed drying such as air flow drying, maximizes strengths and avoids weaknesses, so that the whole machine has a reasonable process structure and excellent performance, truly achieving the low consumption and high efficiency goals of fluidized bed drying.

This machine has an extremely wide range of applications and can be used for dehumidification and drying of rubber additives, pesticides, pigments, dyes, fine chemicals, feed, pharmaceuticals, and some intermediates.

rotateFlash drying machinePrinciple:

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, leading to particle reduction and enhanced 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.

Features:

The special air distribution device reduces equipment resistance and effectively provides the processing air volume of the dryer.

The drying chamber is equipped with grading rings and swirl blades, and the material fineness and final moisture content can be adjusted. (If the final moisture content of calcium carbonate can be adjusted to ≤ 0.1%)

The drying chamber has a high circumferential gas velocity and short material retention time, effectively preventing material sticking to the wall and thermal sensitive material deterioration, achieving high efficiency, speed, small equipment, and large production.

Multiple feeding devices are available for selection, ensuring continuous and stable feeding without bridging during the process.

A special cooling device is installed at the bottom of the dryer to prevent material deterioration in the high-temperature zone at the bottom.

Special pneumatic sealing device and bearing cooling device effectively extend the service life of the transmission part.
