This spray dryer exhaust fan is the third in a set of three we provided for this dairy operation, along with the spray dryer supply fan and a cooling conveying fan. Dairy operations use multi-stage spray dryers to ensure optimal product quality and drying efficiency. The exhaust fan pulls the air and particulate out of the dryer, with airflow components designed to prevent particles from sticking to the fan.
The custom spray dryer exhaust fan is backward-curved with epoxy exterior coating, a Teflon shaft seal, stainless BFM fittings, and continuously welded airstream interior parts made of 304 Stainless Steel with SSPC-SP10 bead blast surface preparation. The application also features a vibration switch, spring vibration isolators, pressure tap connections, a split housing, an outlet transition to round, and a 2” tri-clamp ferrule drain. The Tri-Clamp is sanitary and FDA/USDA approved.
