8.What are the Important Factors Governing the Drying Time of Mesh Belt Dryer?

Many factors govern the drying time of the mesh belt dryer which include:

Type Of Material

If the material has high amounts of moisture it tends to consume more time till it is dried to the desired percentage.

The Thickness of the Material

Materials that are thick and bigger in size tend to take more time in the drying processes. However, the powders and other delicate materials get dried up in lesser time and in greater quantity.

The Humidity of The Air Circulating Through The Dryer

Higher drying rates are attained when the circulating air is less humid so that it has more capacity to withhold water vapors.

The Speed Of The Belt

The speed of the belt needs to be monitored and set up according to the requirement. If the objects are smaller and have less moisture the belt moves faster resulting in quicker outputs while objects that have more moisture content or are bigger in size take more time and hence the belt is set to slower speeds. Setting up the belt at higher speeds can result in improper drying outcomes.
