The process
Cashew shell roasting and drum roasting produce smoke and shell oil fume that is scrubbed, and the dryers and borma ovens need hot air fans. Shell dust and humid air in the processing hall.
The gas
Warm, humid exhaust from ovens, fryers or dryers in a food plant, with light product carry-over. Stainless steel wetted parts and a design that washes down.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| Hot Air Fan | Circulates or supplies air at elevated temperature to a dryer, oven or kiln. | Backward curved and backward inclined |
| Fume Exhaust System | Hoods, ducting and an exhaust fan that capture fume at source and deliver it to a scrubber, bag filter or stack. | Backward inclined and radial tipped |
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | Backward inclined and radial tipped |
| Ventilation Fan | Moves air through a plant or building for fresh air supply, heat removal and fume dilution where the system is ducted. | Backward inclined and forward curved |
