In fluid bed drying equipment standards, the internal diameter of the fluidization bowl/chamber for a 1000-model dryer (such as the FG-1000 or GFG-1000 series) is typically 1.6 meters (1600 mm).
Designed for high-capacity industrial production, this model incorporates a three-stage air filtration system (primary, secondary, and sub-HEPA/HEPA) to ensure process air meets Class 100,000 (ISO 8) cleanroom standards, fully satisfying GMP pharmaceutical requirements.
With a chamber diameter of 1.6 meters, bottom distribution plates and connecting flanges are subjected to continuous thermal cycling and fluctuating pneumatic loads, demanding high structural rigidity and tight geometric tolerances on large-scale components. Based on customer-supplied engineering drawings, Hansheng Automation custom-machines large-diameter (Φ1600mm class) stainless steel air distribution plates, bowl mating ring flanges, and seal-retaining components. We strictly control the flatness and concentricity of large-scale parts to guarantee vacuum airtightness and structural reliability across high-capacity fluidization chambers.
