Intek”s RheoVac DR vacuum drying system is designed for use in a number of industries including: food, pharmaceutical, chemical, and plastics. The system eliminates the guesswork associated with timed runs or off-line sampling to determine drying performance. The RheoVac DR uses a unique probe array to provide real-time data on water vapor flow (rate at which moisture is removed during the drying cycle), pressure (vacuum level actually being achieved in the dryer), total mass and volumetric flow, (operating effectiveness of the vacuum equipment to remove gas and water vapor in comparison to the vacuum pump’s performance curves), relative saturation (output indicating percent moisture content in the vacuum line), temperature (accurate, real-time display of process temperature). The probes are installed in the vacuum line, downstream from the process, to provide an uninterrupted stream of data for evaluating dryer system performance. Removal rates of water vapor and purged gases can be measured separately if needed. The drying process can be viewed in a control room or at a desktop via 4/20 or Ethernet connections. Operators can also view information locally by scrolling between output parameters on the unit”s wall-mounted processor.
