CropLab Falling Number Tester

The CropLab Falling Number Tester is a professional analyser for determining the falling number using the Hagberg-Pertten method. It is used to assess the activity of α-amylase in grain and flour, enabling the determination of germination potential and the processing suitability of raw materials. It is a key tool for grain elevators, grain storage facilities, flour mills and quality control laboratories.

Elevated α-amylase activity impairs baking properties, reduces flour quality and leads to economic losses. CropLab helps identify the problem before processing of the raw material begins.

 

Advantage

  • Objective and reproducible results thanks to a physicochemical method of analysing starch and enzymes
  • Fully automated: heating, stirring, time control, result output
  • Microcomputer control — one-touch start
  • High accuracy and repeatability
  • Built-in self-diagnostics
  • Touchscreen panel and digital display
  • Data transfer to a PC via RS-232
  • Report printing capability (in the printer version)
  • Analysis takes about a minute and does not require highly skilled operators

 

How it works

A flour suspension in a boiling water bath undergoes gelatinisation. The activity of α-amylase determines the degree of starch gelatinisation and the speed at which the stirrer shaft descends.

  • Low fall number → high enzyme activity
  • High fall number → low enzyme activity
