Vacuum dryer combination and advantages

- Mar 29, 2019-

Stirring vacuum drying is a method of volatile components from particles, chemicals, plastics, ceramics, metals. Due to the pressure in the dryer, the boiling point of the liquid is lower than the conditions, and drying can be carried out at a lower temperature. Therefore, vacuum drying is ideal for processing heat sensitive materials without the risk of thermal degradation. It also allows the manufacturer to recycle the solvent or treat the hazardous volatiles removed from the closed system.

The combination of vacuum, gentle heating and agitation achieves significantly shorter drying times compared to the high temperature alone, and atmospheric drying ovens and tray drying operations are often carried out for many hours, sometimes overnight, to achieve low moisture content. The impact on energy costs and productivity is yes. Vacuum ovens and tray dryers provide drying speeds for press dryers, but vacuum dryers. In these systems, the material in direct contact with the heated surface of the dryer is constantly new, dry and uniform.


Another advantage of agitated vacuum dryers is that they can hold a wide variety of materials - from slurries, wet cakes and pastes to granules, granules and powders. For example, the liquid feed can undergo a series of relative changes in the physical state - from slurry to viscous slurry, from slurry to dry powder. The characteristics of the feed, intermediate and final dry products are important considerations when selecting equipment for a particular application. There are many options in the market today, but the three common and common are vertical mixers/dryers, cylindrical mixers/dryers and dual planetary mixers.
