Page 18: Function
Operating hours counter Sequence of functions The FRIABILIMETER is a friability measuring instrument for barley malt. The friability is measured using a mechanical abrasion process. Weigh out a cleaned sample of 50 g on a balance with 0.01 g accuracy, and fill the sample. Pull the pull handle and engage it in the bottom position. -

Start key Figure 10: FRIABILIMETER control elements 7.1.1 Main switch ON/OFF The main switch ON/OFF switches the FRIABILIMETER on and off. After switching on, the "On" LED lights up green. 7.1.2 Pull handle The pull handle applies pressure to the pressure roll, or removes the pressure. -
Page 20: Preparations
Malt samples must be stored in an air-tight container with little or no air inclusion. Fill and seal the container immediately after taking out the sample. It is necessary to calibrate the FRIABILIMETER in relation to a standard malt with a known friability. If the friability result differs from the accepted value by more than r... -
