Air Stream Dryer
Our products have a long life cycle, low maintenance and high quality for their different applications.
Exergy Air Stream Dryer (ExergyASD®)
Exergy Air Stream Dryer is a semi-closed, low temperature dryer designed as stand-alone dryer or as a pre-dryer together with Superheated Steam Dryer (ExergyPSSD®) for two stage drying. The drying air is indirectly heated in a heat exchanger using heating media such as low pressure steam, flue gases, hot water etc.
Wet product is fed into the dryer via an air lock. The product is transported and dried in specially designed drying conduits and separated in an ultra-high efficiency cyclone or bag filter. The dried product is discharged from the bottom of the cyclone/bag filter through an air-lock. Part of the drying air can be recirculated back to the air heater to minimize drying energy need.
Two stage drying for optimal energy utilization
Exergy Superheated Steam Dryer with all its advantages can be installed as final stage dryer. Generated steam from the superheated steam dryer can be used as heat source for drying in Exergy Air Stream Dryer. The drying energy is thus reduced to 50% as compared to single stage drying.
The air stream dryer can use waste heat at low temperatures to dry various products
to required moisture within a few seconds. Combined with the Exergy Superheated
Steam Dryer, you get double capacity but only half the energy and space requirement.
