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.
