空心桨叶式干燥机是一种传导加热的低转速搅拌型干燥机。在干燥器筒体上设置夹套,空心轴上设置空心桨叶,在其中通入热载体,湿物料在搅拌桨叶的搅动下筒体及桨叶热表面进行充分热交换,以达到干燥的目的。
   Hollow Blade Dryer is a kind of mixing dryer at low speed by conducting heating.There is sandwich layer on the tube of the dryer and hollow blades on the axle in which hot carrier is passing through.Wet materials will make heat exchange with the heating surface of the tube and the blades when it is mixed by the blades so as to reach dry.
 
  结构紧凑,传热面积大,占地面积小干燥时用气量小,粉尘少桨叶相互作用具有自净功能物料停留时间长,填充系数高。
  Compact structure,large area of heat conducting,small occu-pied space,less air used when drying and less dust.Blades have selrcleaning function by their interaction and materials have longer dwelling time

  

该机适用于处理各种膏糊状,粒状粉状等热稳定性好的物料,在特殊条件下也可干燥热敏性物料及在干燥过程中回收溶剂。加热介质可采用蒸气,热水,热油等。典型干燥物料有:碳黑,碳酸钙,石膏,粘土,尼龙和聚脂切片,聚已烯,聚丙稀等。

This dryer is suitable to dry various kinds of paste,granules and powder materials which have good heat stability,and can dry

heat sensitive materials under special conditions.Solvent can be retrieved during the process of drying and heating medium can be steam.hot water,hot oil etc.Typical materical to be dried are:carbon black.calcium carbonate,plaster,clay,nyloy and polyester slices,polyethylene,polypropylene etc.
