Airflow pace needs to be controlled for efficient fluidization to manifest. For an efficient drying system, airflow pace really should be optimized. If your speed is simply too superior, then the gasoline will not be heated to our concentrate on temperature. And if it is as well gradual then fluidization will not likely arise.
This point out is known as fluidized state. Just about every granule is thoroughly dried through the as, which envelops them.
Heating: The new air transfers its heat to the stable particles. This heat causes the moisture inside the fabric to evaporate, shifting more info from a liquid to a vapor condition. The hot air also carries absent the moisture vapor.
