Fluid bed dryer with built-in bag filter

Fluid bed dryer with built-in bag filter is a device that integrates a bag filter unit within the fluidized bed. During the drying process, the dusty airflow directly passes through the bag filter for dust removal. The fine powder is captured and returned to the bed layer, thereby reducing material loss. It is suitable for materials prone to generating fine powder, eliminating the need for an external dust removal system. The structure is compact, with a yield increase of over 98%, and is commonly used in drying and granulation processes that require efficient recovery of fine powder.
