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:

Technical Specifications

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 withstand the high temperatures, abrasion, and mechanical stresses encountered in fluid bed drying processes. Materials like polyester, polypropylene, PTFE (Teflon), and fiberglass 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.

Filtration Mechanism –

The filtration mechanism in fluid bed dryer bags is based on the retention of solid particles within the bag while allowing heated air or gas to pass through. The filter media captures and holds the particles as the drying process progresses.

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.

Maintenance –

Regular maintenance of fluid bed dryer bags is essential to ensure efficient drying and product quality. Depending on the type of material being processed and the frequency of use, bags may need to be cleaned, replaced, or reconditioned.

Customization –

Fluid bed dryer bags can be customized in terms of material, size, and design to suit the specific requirements of the drying process and the characteristics of the material being dried

Note –

 Not all Usha Filters products are washable, as due to washing filter media fibers get weak and damaged which may later effect filter poor performance. Please consult manufacturer for same.We provide detailed cleaning manual.

 Filters can be made various tailor made size and type as per customer requirements with respect to thier application, fitment, Usage, desired flow, particulate matter concentration load and filtration class required.
