◆Feeding liquid can be solvent,suspension or emulsion,which is conveyed through a high pressure pump to a atomizer (spray gun)on the top of the tower.
◆The liquid from pressure gun atomizes to enter high speed airflow intower,the atomized droplets are driven from downward air stream to the fluidized bed and are dried into particles.
◆While the particles go into the fluidized bed,the airflow runs in reverse flow and is discharged from the top of drying tower.
◆The ultrafine particles separated from discharged air are re-circulated back into drying tower.Fluidization within the fluidized bed,fine powder circulation,and particle movement within the dry gas stream occurs in an air environment that is higher dust density of conventional drying systems.To overcome the problem of particle surface bonding,high water content of particles can be dealt with.
◆The moisture content of particles entering fluidized bed can be controlled to a certain extent,resulting in larger particles and structural changes (agglomeration or granulation).
◆When it necessary,the final drying and cooling of the product can be carried out in another external fluidized bed connected to the outlet of the built-in fluidized bed.
◆Large adjustment range of product particle size,water content;
◆The total height of equipment is lower than original parallel tower;
◆Energy saving,due to high negative pressure evaporation on top of wind return chamber of tower,it reduces the evaporation temperature
and saves both heat and energy;
◆Product quality is good,uniform particles,wide particle size adjustment range,particle color,flush performance is better.
