Application: Dryer
This installation features a high-pressure ID fan design with a shrouded and oversized impeller for an industrial dryer.
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.
The radial-tipped design provides high static efficiency while resisting material buildup on the impeller. With self-cleaning capability, it keeps dust and other particulates moving through the wheel to exit the fan.
We supplied this radial tipped dryer supply fan for a cement plant application. With a 150 HP motor, an outlet flex connector or expansion joint, and an airflow sensor, the fan accommodates very high airflow.
In this installation example, we designed and delivered a high-efficiency induced draft fan for a hemp dryer system. The system uses the fan to pull air and particles through, controlling flow using an inlet damper.
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.
Centrifugal Fan Functions for Industrial Dryer Applications
Industrial dryers like the rotary dryer and others remove moisture in the production process of various foods, chemicals, biofuels, and other products. The rotary dryer handles a wide range of materials with different sizes and levels of corrosion. It uses a large drum that rotates to dry the material with a direct combustion-heated gas stream.
