Vertical FBD could be the most generally made use of dryer in the pharmaceutical business and is simple and easy to work and retain.
Airflow velocity needs to be controlled for efficient fluidization to come about. For an effective drying procedure, airflow pace ought to be optimized. When the pace is just too high, then the gas won't be heated to our target temperature. And whether it is also slow then fluidization will likely not come about.
Mechanical shaking is The simplest way to clear away the dust layer and it is finished via the pneumatic cylinder on the set intervals and seems We've got two filtering chamber the shaking is alternated amongst The 2.
This drags read more and condenses the h2o Or dampness in the air and can make it dry. The chilled drinking water piping (supply and return line), along with, the control valve are beyond the AHU.
