The feed inlet of the fluidized bed is equipped with a distribution device to allow the wet salt to enter the fluidized bed evenly, preventing the wet material from entering the fluidized bed into lumps and forming hard lumps of salt.

Set up the fluidized bed mixing zone. The wet materials dispersed by the distribution device fall evenly into the mixing area and are fully mixed with the dry materials in the bed to prevent the wet materials from clumping into blocks and being instantly heated and scarred when entering the fluidized bed, and accumulating in the blanking area, causing agglomeration and the fluidized bed been stuck.

The reasonable discharge port structure (the combination of the quick discharge door and the overflow weir) will ensure product quality and discharge a very small amount of lumps produced during the fluidization drying process through the quick discharge door at the lower part of the discharge end to prevent the lumps from being The dead bed phenomenon of the fluidized bed occurs internally, and the product is discharged through the overflow weir at the discharge end.

According to the special properties of the material (particle size, fluidity, moisture content, viscosity, etc.), a reasonable air chamber structure is designed to control a reasonable fluidization speed (while ensuring normal fluidization, try to reduce the wind speed), which effectively reduces the system operation Energy consumption, while ensuring the uniformity of material particle size and good product quality.

The system adopts a composite fluidized air distribution plate structure with uniform air outlet gaps, which effectively improves the fluidized state of the material. There are no dead corners or blow-through phenomena. The material is fluidized evenly and can effectively prevent the material from leaking into the lower air chamber. And due to the use of the side air outlet structure can make the material move to the discharge port continuously and stably, achieving controllability of the residence time of the material within the design range of the dryer. At the same time, the agglomerated materials can move to the discharge port in a smaller volume and be discharged in time. Fast material to prevent dead beds caused by the generation of large pieces of material.

The equipment occupies a small area and has high thermal efficiency. The reasonable internal heat exchanger structure ensures normal fluidization of materials and improves the heat exchange efficiency of the heat exchanger.
