Meaningful dough examinations for achieving best baking results
On the basis of the recorded extensogram, reliable information on rheological dough properties – and therefore later baking results – can be determined. Recognize and determine the effects of flour additives, such as for example enzymes or ascorbic acid, and flexibly adapt the short methods to your own particular application.
The ExtensoGraph forms part of the proven Brabender 3-Phase-System for holistic and practice-oriented simulation of the baking process on a laboratory scale, together with the FarinoGraph (determination of flour water absorption and dough kneading properties) and the Amylograph-E (prediction of starch gelatinisation, enzyme activity and baking properties).
Automation and digitization advantages
Compared to the predecessor model Extensograph-E, the ExtensoGraph impresses with:
- An integrated PC and touch screen as well as an integrated temperature control
- Automated processes for test execution (rounding and long moulding, fermenting, stretching)
- Controlled and adjustable operating conditions (temperature, humidity) for optimum results
The ExtensoGraph is operated by the browser-based Brabender MetaBridge as standard device software.
Your advantages include:
- Access to live measurement results from any location and terminal device.
- Automatic transmission of FarinoGraph readings as part of the dough preparation process
- Correlation of measurement results and comparisons between different measurements / dough samples
- Support of third-party systems (e.g. LIMS) via Brabender WebAPI, OPC UA
The dough previously created in the Farinograph is rounded and stretched out in the Extensograph. After defined settling times and temperatures have been reached in the cooking chambers provided for the purpose, the dough is stretched until it tears. The dough’s resistance is automatically measured and recorded. This test procedure is based on processes that are usual in bread and bread roll manufacture.
The extensogram, which is recorded online during the ongoing measurement and displayed on the screen, shows the force as a function of the elongation path (time). The quality of the flours and additives used is clearly characterized by the following parameters:
– Profile of the measurement curve
– Area under the curve
– Numerical values of the evaluation
The extensogram shows:
– Strain resistance (5 cm)
– Elongation resistance (Max.)
– Area under the curve (energy)
– Ratio (elongation resistance 5 cm /elongation)
– Ratio Max (Stretch Resistance Maximum / Stretchability)

Brabender devices with this function have a built-in computer and a touch display. This allows our customers to directly and easily start operating our devices without any IT experience. Combined with other Brabender technologies such as EmbeddedHC, this results in a very compact device setup.
The MetaBridge Connect technology provides various data exchange interfaces and flexible connectivity features. Data sharing between all Brabender MetaBridge devices in one network allows for smart workflows and process efficiency. Moreover, the integrated web-based software interface (WebAPI) connects and automatically exchanges data with natively connected database systems and / or 3rd party laboratory information and management systems (LIMS) or ERP solutions.
MetaBridge Correlation is an optional software package for performing correlation studies across multiple data sets. It allows for comparison of multiple measurements and parameters in a tabular and in an interactive graphical view. Particularly for quality control purposes, the compliance with a pre-defined tolerance is automatically evaluated and highlighted.
The MetaBrigde Database represents a local data center in the customer network and a basic laboratory information and management systems (LIMS) for Brabender devices. Connected Brabender devices transfer measurement results automatically into the central MetaBridge database. Besides of the backup functionality, statistical analysis and crossdevice correlations between multiple data sets can be performed.
labfolder allows you to store, manage and search your measurement data in one central location, independent of the instrument. Brabender MetaBridge instruments have an automated built-in connection to labfolder. It’s never been easier to get started with lab digitization.
