PowderPro A1 — CCD image-based angle measurement

CCD + Patented Vibration Technology

Full Automation, Zero Operator Error

The high-resolution CCD camera instantly photographs the powder surface; the automatic image recognition algorithm determines angle of repose, angle of fall, and spatula angle with high repeatability. The patented rotary vibration system creates a homogeneous, level powder surface before every measurement.

📷
CCD Image-Based Angle Measurement
The CCD camera automatically photographs the powder cone and the image recognition algorithm calculates the angle — angle of repose, angle of fall, and spatula angle — without any manual reading error and with high inter-operator reproducibility.
🔄
Patented Rotary Vibration System
3D electromagnetic rotary vibration combined with cylinder rotation creates a horizontal, homogeneous powder surface before each measurement cycle. Delivers unmatched repeatability in tapped density determination compared to conventional vertical tapping mechanisms.
⚖
Automatic Balance Integration
The connected electronic balance transmits weight data directly to the system. Manual transcription error is eliminated; bulk and tapped densities are calculated in real time with no additional user input.

Frequently Asked Questions

What You Wonder About

Automatically measured parameters: angle of repose, angle of fall, spatula angle, bulk density, tapped density, dispersibility, voidage, and cohesion. Automatically calculated parameters: angle of difference, compressibility (Carr index), uniformity, flowability index, floodability index (Hausner ratio), and sieve size. All 11 parameters are obtained in a single measurement run.

In manual measurement, the operator estimates the powder cone angle visually or with a protractor — a method that introduces high operator-dependent variability. The PowderPro A1's CCD camera instantly captures the powder surface and the image recognition algorithm calculates the angle automatically. The result is operator-independent, reproducible, and fully documentable measurement data.

The variable-frequency rotary vibration system is adjustable from 50 to 300 taps per minute. Combined with selectable 3 mm or 14 mm amplitude, the cylinder rotation motion creates a horizontal, homogeneous powder surface before each measurement. This approach produces more repeatable tapped density results compared to conventional vertical-drop tapping mechanisms.

Yes. A separate SOP profile can be defined for each product or material, specifying the test sequence, vibration parameters, and acceptance criteria. The operator simply loads the sample, starts the system, and retrieves the result. Cross-contamination and operator-induced variation between products are prevented in GMP environments.

The PowderPro A1 is fully compliant with ISO 3953:1993 (tapped density), USP 32-NF27, and Ph. Eur. 7.0 (07/2010:20934E). These standards define international measurement references for tapped density, bulk density, and powder flowability parameters used in pharmaceutical quality control and industrial process development.
