Grain and oil machinery - Bran brush
1 Scope
This Standard specifies bran brush’s working principle, model and basic parameters,
technical requirements, test methods, inspection rules and marks, packaging,
transportation, and storage requirements.
This Standard applies to vertical-type bran brush [Translator note. hereafter also known as.
brush-bran or brush-bran machine] that processes flake-shaped or crumb-shaped bran in
wheat processing.
