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.
