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. Press the start key. The pressure roll presses the grains of
barley malt against the rotating sieve drum with a constant spring pressure. The friable constituents fall
through the wire mesh. Glassy grains and hard fragments remain in the sieve drum. The FRIABILIMETER
switches off automatically after eight minutes. The remaining constituents in the sieve drum are
weighed back and this information is used for calculating the friability value out of one hundred.
For precise information about operation, refer to
chapter 7.
