Click to ViewThe Falling Number System measures the alpha-amylase enzyme activity in grains and flour to detect sprout damage, optimize flour enzyme activity and guarantee soundness of traded grain. Alpha-amylase activity is crucial for final product quality of bread, pasta, noodles and malt. Anyone handling wheat, barley, rye or sorghum intended for these applications will benefit from the Falling Number system.

  Working Principles
Click to ViewThe Falling Number is defined as the time in seconds required to stir and to allow a viscometer stirrer to fall a measured distance through a hot aqueous meal, flour or starch gel undergoing liquefaction due to alpha-amylase activity. The device automatically measures enzyme activity in flours and wheat. FN measuring mode is used for determining natural alpha amylase enzymes. FFN measuring mode is used for determining total (micro-biological + natural) alpha amylase enzymes. Changing from FN mode to FFN mode or vice versa can be made by single button. The device automatically adjusts the boiling temperature according to the elevation.

  User Instructions
Wheat flour, Composite flour 1. Use only distilled water for filling boiling chamber and sample preparation. 2. Use only thermo paper for printing.
