The feed was pulverized in a rotary
atomizer with an airflow produced by a blower with an air flow rate
at 56 ± 2 m3 h1. Samples from the collection vessel were recovered,
weighed, sealed in amber glass flasks and stored in dark at
4 C until further analysis. Drying efficiency and powder recovery
(Marabi, Livings, Jacobson, & Saguy, 2003) were calculated. Particles
deposited on the dryer chamber were discarded. All processes
and analyses were carried out in triplicate.
