In direct heat rotary dryers a continuous feed of wet particulate material is dried by contact with heated air, while being transported along the interior of a rotating cylinder, with the rotating shell acting as the conveying device and stirrer. We offer rotary dryers in co-current (parallel) and counter-current operation. In the former the wet material is exposed to the hottest air, which enables heat sensitive or sticky materials to be dried successfully. In the counter-current operation dried material is exposed to the hottest air helping to achieve very low moisture content.

PREMIUM offers Rotary Vacuum Dryer for Drying of wet cakes of dyes, pigments, intermediates and various other products where either solvent is to be recovered or drying is to be achieved at relatively low temperature. Rotary Vacuum Dryer is very useful in drying the material in a relatively low time for sticky and difficult to dry products. The construction of Rotary Vacuum Dryer contains a central hollow shaft with a specially designed hollow arms which are heated by either stam or Thermic Fluid, rotating in a centrally jacketed shell where-in the gap between shell and jacket is usually 3-7 mm. The entire shell area is effectively covered by the scrapper arms leaving no part in the shell where the solids could stick. The results in a continuous agitated drying which reduces the drying time.

This filter is used for solid and liquid separation which is aided with the application of vacuum and cake squeezing by mechanical means. The process is totally enclosed, hygenic and safe which make it ideal for processing toxic and hazardous material human contact.Cake discharge is done with the help of stirrer. Provision for spraying wash liquir is in build in the equipment. This equipment can be operated under pressure or in vacuum or in combination of both.It can be used as a drier to further reduce the moisture content. Step less regulation of speed. A totally hydraulic operation make it simple and easy for operation and compact. For more details please contact us.

Clean, simple and very effective method of drying wet cake, powder and even the slurry. The drying is under vacuum and hence it is possible to dry heat sensitive materials at temperatures well below 100°C without suffering the problem associated with very long drying periods. Valuable organic solvents can also be conveniently condensed and recovered. Production rate can be greatly increased. Minimum labor can be employed. Over all profitability of an industry can be increased.
