Vacuum Drying Monitors

Vacuum Drying Monitors

The RheoVac DR is a monitoring system that eliminates the guesswork involved with vacuum drying operations.  It monitors several parameters in the vacuum chamber exhaust line, before the vacuum pump or ejector, to provide a real-time, detailed look at the drying process.  This view of the process can be used to chart the drying cycle, make informed decisions about changes to the process and quickly evaluate the impact of these changes.  One chemical manufacturer reported reductions of approximately $2,000,000 in operating costs over a four-year period.

What Are the Benefits?

• Decreased drying time -  Cycles can be reduced by as much as 40%
• Increased capacity and throughput – Production bottlenecks created by the drying process are reduced.
• Improved product integrity – Elimination of off-line sampling reduces risk of product contamination.
• Reduced costs – Closer control and shorter cycles reduce energy consumption and maximize yield.
• Tighter process control – Multiple process variables are monitored simultaneously. 

How Do They Work?

RheoVac DR uses a dual probe system to measure or compute these parameters:

• Water vapor flow: the rate at which moisture is being removed during the drying cycle.
• Pressure: the level of vacuum actually being achieved in the dryer.
• Total mass flow and actual volumetric flow:  actual operating effectiveness of the vacuum equipment to remove gas and water vapor in comparison with the vacuum equipment’s performance curves.
• Relative saturation: an output that shows the percent moisture content in the vacuum line. 
• Temperature: accurate, real-time display of the process temperature.
