The spray dryer supply fan application uses a custom backward-curved fan with epoxy exterior coating, and continuously welded airstream interior parts made of 304 Stainless Steel with SSPC-SP10 bead blast surface preparation. With a split housing, vibration switch, split vibration isolators, pressure tap connections, and an outlet transition to round, this fan is heavy-duty and food-grade.

Dairy operations use multi-stage spray dryers to ensure optimal product quality and drying efficiency. The supply fan pulls the filtered air into the dryer vertically at high velocity, with airflow components designed to prevent particles from sticking to the fan or the inside of the dryer chamber. We provided multiple fans for this dairy operation. Find more information in our Cooling Conveying Fan Installation write-up.
