Spray Dryer Equipment Introduction: The spray-dried raw material liquid may be solution, emulsion, suspension, melt or paste liquid. The dried product may be in the form of powder, granules, hollow spheres or pellets as needed. The atomizer that disperses the feed liquid into droplets is the key component of spray dryer. A pressure atomizer is used to obtain a high pressure by a high-pressure pump. When the high-pressure liquid passes through the nozzle, the pressure energy is converted into kinetic energy and dispersed as droplets at a high-speed discharge. The hot air and the atomized droplets undergo heat transfer and mass transfer processes, and the droplets are dehydrated and dried into powder, granules, hollow spheres or pellets. Due to the fast heat transfer and mass transfer in the tower, it is especially suitable for the drying of heat sensitive materials, has better heat transfer efficiency. Working Principle: Liquid material is atomized through a special pressure nozzle with a high-pressure pump. Hot air enters the dryer after being adjusted by an air distributor. The material and hot air is mixed in the dryer, rapidly carries on heat and mass transfer. Powder or granular products are produced in a very short time. Products with larger particles size are discharged form the bottom of the dryer, smaller particles enter the cyclone with hot air. The exhaust gas is discharged into the air after dust removal in a scrubber. Applicable Materials: Chemical industry, Food industry, Pharmaceutical industry, Building materials industry, Environmental protection industry.
