Granutools has released a new generation of its GranuDrum powder flow rheometer, featuring automated data interpretation via the Granulyzer AI. The instrument, available in Classic and High Temperature models, aims to improve the speed and accuracy of powder material characterization.
Why it matters
By automating diagnostics and measurement, the system addresses the need for faster, repeatable powder metrics in industrial manufacturing. This release targets increased process reliability through standardized testing protocols.
The device achieves data capture at 60 frames per second using 3088 by 2076 pixel resolution across a rotation speed range of 0.1 to 250 rpm. The High Temperature model extends operational capacity to 250 degrees Celsius.
The players
Granutools
A developer of laboratory instrumentation specializing in powder flow and material characterization hardware.
The details
The GranuDrum uses rotating drum technology, where a vessel containing powder rotates at controlled speeds to observe the material's behavior. Image analysis algorithms quantify powder metrics, which are then processed by the Granulyzer AI — a software layer that performs automated diagnostics and data interpretation. The system includes a motorized door for sample handling and supports standard data exports in PDF and XLS formats.
Timeline
September 29 to October 1, 2026: Granutools displayed the new GranuDrum at POWTECH TECHNOPHARM in Nuremberg.
The Tech Race
This development aligns with recent moves toward ISO/ASTM TR 52952:2023 compliance to ensure measurement consistency across the industry. It marks an effort to formalize automated data processing in materials science against previous, more manual evaluation benchmarks.
The system is currently available in two versions, including a High Temperature model for specialized environments. Users can leverage the automated Granulyzer AI to export results directly into XLS or PDF files, streamlining lab workflows that previously required manual data sorting.
The takeaway
The addition of the Granulyzer AI shifts the bottleneck of powder analysis from data capture to interpretation. Researchers should look for performance comparisons against ASTM D8648-25 benchmarks to verify accuracy gains in their specific material workflows.
