Vacuum dryers is a revolutionary device that uses vacuum to accelerate the resin drying process. The use of vacuum provides many process and cost benefits compared to conventional drying technology.
Speed of drying: Typically the vacuum dryer will dry materials in one-sixth the time of a desiccant dryer. If your desiccant drying time is 4 hours, the vacuum dryer will do the job in 40 minutes. The result is time savings of 3 hours and 20 minutes every time you start up a dryer. This not only represent reduced energy cost, but could also represent 3 hours and 20 minutes of additional production time.
Energy savings: Side-by-side testing of the vacuum dryer and desiccant dryer shows reduced energy consumption of 70 to 80 percent. The key to the reduced energy consumption is that the vacuum dryer does not rely on desiccant. Desiccant, once saturated, must be regenerated by a heating and cooling process so it will again be able to absorb moisture. All energy required to regenerate desiccant is lost to ambient.
Reduced maintenance: Since desiccant degrades over time it must be replaced on a regular basis. This expense is avoided with a vacuum dryer. In addition the need to monitor the condition of desiccant is eliminated.
