Fluid Bed Dryer Bags
Fluid Bed Dryer Bags
Fluid bed dryers are industrial drying machines used to remove moisture or solvents
from solid materials by suspending them in a stream of heated air or gas. Fluid bed
dryer bags, also known as fluid bed dryer filter bags or fluid bed dryer filter sleeves,
are essential components of these machines. They help to separate and retain the
dried material while allowing the hot air or gas to pass through. Here’s an overview
of fluid bed dryer bags :
Purpose
Fluid bed dryer bags serve the primary purpose of containing and retaining solid particles or
granules being dried within the fluid bed dryer chamber. They ensure that the material is
properly suspended and exposed to the heated air or gas for efficient drying
Construction
These bags are typically constructed from specialized filter media designed to with stand the high
temp, abrasion, and mechanical stresses encountered in fluid bed drying processes. Materials like
polyester, polypropylene, PTFE (Teflon), and fiber glass are commonly used for the filter media.
The bags are cylindrical or tubular in shape, with one end closed and the other end open. The
open end is attached to the fluid bed dryer’s outlet.
Applications
Fluid bed dryer bags are used in a variety of industries and applications, including:
- Pharmaceutical manufacturing: For drying granules, powders, and particles in the pharmaceutical industry.
- Chemical processing: In the drying of chemical substances and powdered products.
- Food and beverage: In the production of food products like instant coffee, powdered milk, and breakfast cereals.
- Mineral processing: For drying minerals, pigments, and dyes.
- Agrochemicals: In the drying of fertilizers and agricultural chemicals.
- Plastics and polymers: For drying plastic pellets and resin powders.
