What filter materials are used in exhaust bags?

Conductive anti-static polyester needle felt or Gore-Tex PTFE membrane filter bags.

How is the bowl cleaned between products?

A CIP arrangement with spray balls covering the bowl, lid and chopper housing is available, and the cleaning cycle is recorded. Cleaning validation with swab and rinse recovery is offered as part of our validation service.

What warranty applies to this machine?

Machines are supplied with a 12-month warranty from commissioning covering manufacturing defects, with wear parts and tooling excluded. Extended cover is available under an annual maintenance contract, which also fixes response times for breakdown attendance.

What documentation is supplied at handover?

Handover includes the operation and maintenance manual, electrical and pneumatic schematics, the spare parts list with part numbers, material test certificates for contact parts, sensor calibration certificates and the completed qualification dossier.

How is the granulation endpoint determined?

The endpoint is determined by impeller power draw and torque trend, recorded against the batch. Machines can additionally be specified with inline near-infrared or focused beam reflectance measurement for products where power draw alone is not discriminating.

Is the vessel suitable for solvent-based granulation?

Flameproof configurations to Ex d IIB T4 are available for solvent processing, with nitrogen inerting, oxygen monitoring and earthing continuity monitoring included as part of the package.

Overview

About the FBD-250 Fluid Bed Dryer and Granulator

The **FBD-250 Fluid Bed Dryer and Granulator** is engineered for high-efficiency drying, agglomeration, and top-spray granulating of pharmaceutical powders and granules. Featuring a 250 kg working batch capacity within a stainless steel AISI 316L expansion chamber, the FBD-250 utilizes conditioned process air to achieve rapid, uniform moisture reduction.

2-Bar Pressure Shock Resistant Construction: Heavy-gauge AISI 316L vessel with burst relief ducting.

Top-Spray Agglomeration Array: Triple-head peristaltic liquid binder spray nozzles deliver uniform droplet size.

Torque-Trended Endpoint Control: Impeller power draw is trended live against the qualified profile so the endpoint is determined by data rather than elapsed time.

Contained Charging and Discharge: Split-butterfly or equivalent contained transfer keeps operator exposure within the occupational limit for potent compounds.
