The VolScan Profiler is a benchtop laser-based scanner that measures the volume of bread and bakery products. 

This non-contact measurement system offers considerable advantages over contact and displacement techniques which purely measure volume. The rapid 3-dimensional digitisation of products enables the automatic calculation of several detailed dimension related parameters, the results of which may be mathematically manipulated for immediate use or future retrieval in a variety of data formats.

With the Volscan Profiler, manufacturers have a precise and fast method for the measurement of the volume of bakery products in order to be able to control and monitor the breadmaking conditions and ingredient performance.

  • Measurements are operator independent

How the VolScan Profiler test works 

The product is mounted at each end or located by a suitable mounting device tailored to the specific product. Parameters entered into the software by the operator for each batch under test include: sample ID name, date, flour weight, bread type and batch code [1]. 

This assessment can be done rapidly, the results being obtained in a period ranging from a few seconds to a few minutes depending upon the chosen interval (0.5mm to 26mm) and the preferred precision [1]. 

Parameters and Calculations can be defined by the user, providing maximum flexibility of data reporting requirements [2/3]. The product is then automatically weighed and an eye-safe laser device scans vertically to measure the contours of the product at selectable intervals whilst the product rotates. Each interval consists of 400 data points providing a detailed profile of the product [4/5].  


A full guide is available in Help file format [6] to assist in setting up and performing tests, explaining the calculations and advising on optimum test settings to suit your product [7].

Data Analysis, manipulation and viewing options 

Once the test is complete the following measurements can be quickly determined: volume, length, maximum width, maximum height, height at the maximum width and width at the maximum height [8].

These numbers are then further manipulated to automatically calculate and display the Specific Volume of the product  based on the total weight (Volume/product weight) and the volume yield of the bread based on the weight of the flour used (Volume/100g flour).  

The scanned data can be viewed in both 2D and 3D representations to allow comparisons with previous archived measurements. Within the 2D sectional view, additional automatic and manual measurements can be made on chosen intervals or 'slices' of the test data [9/10]. 3D views of the product are rotatable in all planes providing flexibility of viewing for visual comparison and presentation [11].

All data is saved in spreadsheet files for easy access and analysis [12]. This data can be viewed in or exported to Microsoft Excel.

Data can be sorted by any column header and statistics adjusted according to new data selection. 

Results can be quickly emailed by clicking on the Mail To button [13] which automatically opens up a message window in Outlook and attaches the active window [14].

A Report template is available into which your data can be dropped and automatically positioned with test data fields or modified using full Report Editing tools and saved as a .pdf file [15]. 

Alternatively, images and data can be copied and pasted into other applications [16].
