ISI 34-1e Determination of Baumé of Starch Slurry by Aerometer

1. Scope The method is applicable to starch slurry


LT 15 Jan 1998
2. Principle Slurry density is interpreted as concentration of slurry


3. Apparatus 3.1 Aerometer 0 - 10 Béo
3.2 Aerometer 0 - 25 Béo
3.3 Cylinder, slim 100 ml


4. Procedure Keep aerometers floating in cylinder or bucket with water.
Fill cylinder (3.3) to the brim with starch slurry. Immerse appropriate aerometer (3.1 or 3.2) and let float.
Read immediately the degree of Baumé on aerometer stem


5. Calculation Report reading as starch concentration in degree Baumé (Béo) with one decimal


6. Note Entrapped air has to be released and starch re-slurred before aerometer is read.
The centrifuge is superior to the aerometer as a process tool being indifferent to entrapped air and rapid settling starch. ISI 33
