RheoVac® DR Drying Monitor

Vacuum drying plays a crucial role in manufacturing processes across various industries, and achieving precision in mass flow rate measurement is key to optimizing performance. Bionetics’ RheoVac DR Vacuum Monitoring System is designed to enhance and streamline your vacuum drying operations by providing accurate, real-time insights into the process. Positioned in the exhaust line of the vacuum chamber, the system measures key parameters to provide a precise mass flow rate of water vapor extracted during drying.

This advanced system allows users to monitor and adjust the drying cycle effectively, helping to optimize the process and achieve significant operational cost savings. For example, one of our chemical manufacturing clients reported approximately $2 million in savings over four years by implementing our RheoVac DR system.

Benefits of Using Our Vacuum Drying System

Our vacuum drying system is extensively used across industries to measure the mass flow rate. The following benefits have contributed to its easy acceptance and popularity.

• Decreased drying time -Shorten drying cycles by up to 40%, increasing the efficiency of your vacuum drying method.
• Increased capacity and throughput – Accurate flow rate measurements enable informed decision-making, eliminating production bottlenecks and boosting overall dryer capacity and throughput.
• Improved product integrity – Eliminate off-line sampling and reduce the risk of product contamination, ensuring better final product quality.
• Reduced costs – Shortened cycles lead to lower energy consumption, better yield, and enhanced cost efficiency.
• Tighter process control – By monitoring the total mass flow, you can achieve more accurate measurements, ensuring that the right amount of materials is used in each stage of the process. This minimizes waste and overuse, leading to more efficient operations.

Process Parameters Achieved Using RheoVac Vacuum Monitoring Instruments

The RheoVac DR uses a dual probe flow measurement and three other primary process measurements to determine when dry conditions are met. Here are the process parameters you can achieve accurately, and use the output data to chart the drying cycle for further improvements.

• Water vapor flow: This is the rate at which moisture is removed during the drying cycle.
• Vacuum Pressure: This is the actual level of vacuum in the dryer.
• Total mass flow and actual volumetric flow: This is the actual operating effectiveness of the vacuum equipment in removing gas and water vapor in comparison with the vacuum equipment’s performance curves.
• Relative saturation: Track the moisture content in the vacuum line, enabling precise process control.
• Temperature: Monitor the process temperature in real time, ensuring optimal drying conditions.
