In the receiver pan (i.e. the fraction < 100 µm), no test substance was collected.

Conclusions:
Particle size distribution of Vinasses by dry sieving was successfully performed. In the receiver pan (i.e. the fraction < 100 µm), no test substance was collected.

Description of key information

Liquid Vinasses:

not applicable

Solid Vinasses:

Particle size distribution at different passages:

< 500 µm: 0%

500 - 2000 µm: 0.2%

> 2000 µm:  99.8%

Additional information

The result for solid Vinasses is derived from a study with Vinasses, residue of fermentation containing biomass of Corynebacterium glutamicum (Method: CIPAC, Physico-chemical Methods for Technical and Formulated Pesticides, MT 59: "Sieve Analysis"). Since all Vinasses are very similar in composition, particle size distribution is as well similar. The particle size distribution (granulometry) study does not need to be performed for Vinasses, which are marketed or used only in forms of suspension (aqueous solution) and pastes.
