Spin Flash Dryer
PrincipleHot air enters into drying chamber from the bottom of dryer with appropriate spouting speed. Raw material is crushed by dis-integrator and dried by hot air. After being crushed,Website:, raw material could have bigger surface area. Bigger surface area of raw material and speed difference between raw material with hot air increase drying efficiency.Features1 There are several feeding systems available, we can get stable feeding without bridging phenomenon2 There has cooling system on agitating part of dryer, avoiding over-heat of raw material.3 Special designed gas sealing device and shaft cooling device to lengthen life span of driving system.4 Special designed air distribution system, which could reduce air pressure drop, improve efficiency of hot air5 There has classification ring in dryer chamber, size and final moisture content of product is adjustable.6 It could increase bulk density of product compared with other drying equipments7 There has high spiral air speed inside dryer, drying time is short, it could prevent wall-stick problem, and metamorphism of heat-sensitive material.8 There has air blowing system, blowing air from bottom of dryer with 30-60m/s speed, it could prevent powder back to hot air pipe.9 relatively low outlet air temperature, to improve drying efficiency.10 Strong disintegrating system and spiral hot air could crush material, and obtain fine, uniform product.Technical ParametersModelDiameter of drying chamber (mm)Main machine size (mm)Power of disintegrator (kw)Air volume(m3/h)Evaporated moisture (kg/h)Occupied area(m2) XSZ-2200250*28000.75-2.*2500XSZ-3300400**2700XSZ-4400500*35004-7.*3000XSZ-5500600*40005.*3200XSZ-6600700*42007.5-18.*3250XSZ-8800900*460011-18.*3500XSZ**3750XSZ**4000XSZ**4250XSZ**4500Note: The table is based on 200℃ inlet air temperature and 80℃ outlet temperature. Final dryer model is depends on raw material feature.
