Low Energy Consumption Flash Dryer for Drying Chemical Material

The flash dryer has up to three drying stages.Recirculation of the drying air minimizes energy consumption.For low particulate emissions,a combination of high-efficiency cyclones and a secondary scrubber can be used.ANDRITZ slab press.The slab press compacts the pulp fluffs from the flash dryer into bales.Each bale consists of two slabs.Apr 01,2014&0183;With increasing concern about environmental degradation,it is desirable to decrease energy consumption in all sectors.Drying has been reported to account for anywhere from 12 to 20% of the energy consumption in the industrial sector.Drying processes are one of the most energy-intensive unit operations in the CPI.
