Malting Barley Inspection VideometerLab with Autofeeder
Incoming barley may be inspected 8-9 grams at a time in 90 mm petri dishes. This is flexible but often we need to test larger samples then VideometerLab can be equipped with the autofeeder option shown on the left.
With the autofeeder it is possible to measure samples between 50-1500 g.
Running the same sample through many times over several months and adulterating a large sample (560 g) with a handful of Fusarium spp. grains shows that this analysis has a high reproducibility among several presentations and over time. It also shows that the sensitivity is high compared to the variation of the analysis.
High Reproducibility and Sensitivity
The following examples shows the results of quality inspection performed on the same sample of 560g of malting barley over a period of 3 months.
The sample was analysed and measured repeatedly over time with the VideometerLab with Autofeeder option.
As shown by the results, the autofeeder option allows for high reproducibility in results over time. Additionally, we are shown that by adding few infected and partially infected seeds to the 560 g sample gives a significant rise in detected infection level.

Why Is Malting Barley Quality Control Crucial for Breweries?
Malting and brewing have become increasingly more sophisticated, being the second largest usages for barley.
Nowadays, barley is both processed and analysed with advanced technologies, such as spectral imaging. These can automate, expedite, and standardize all operations, so to make them more reliable and safer.
For a malt producer barley quality is of paramount importance. A mold infection will potentially destroy the malt and may be catastrophic for the breweries, that are the malt customers. To secure the quality of the finished malt and its further use for brewing it is important to analyse the incoming barely in order to assure the quality of the malt.
The VideometerLab instrument inspects an incoming barley sample for a number of the most important quality parameters. This is done fast, accurately, non-destructively, and simultaniously. It is also cost-efficient since is does not need time-consuming sample preparation or chemicals.
Malting Process Optimization
For a malt producer it is important to accurately control and progress the different stages of the malting process. In order to do this then a number of important parameters can be measured along the malting process line. The parameters are:
All four malting process analyses are performed by the same VideometerLab instrument, and the automated recipes are illustrated in the images above. All recipes may be adjusted for other grain types like wheat.
