FEED-MASTER Rate Control

In the real world, process manufacturing conditions do not stay constant from one feed to the next feed – flow rates vary due to levels in vessels, material consistency flow characteristics of materials, pump conditions, and other factors.

Hardy's proprietary FEED-MASTER predictive/adaptive algorithm adapts for the flow variation in real time during every feed.  This method is called “rate control”.

The algorithm is used to capture the current Rate of Change (ROC), the value based on the current flow, and a second algorithm is used to predict the change needed to the current feed based on real time flow rate changes monitored during the feed.

The smart algorithms adapt to requirements, such as using less severe multispeed feed control (speeding up feed times). And in some cases, a higher feed rate can be used to deliver exceptionally accurate feed results and at the same time deliver optimized material feed and batch cycle times.
