BOA Compactor

Ottevanger’s BOA Compactor, patented pre-compacting technology,
a unique alternative for double pelleting or expanding. A doublewalled
mixing chamber in which steam and liquids are introduced
and the mixture is compacted using an hydraulically operated
compacting chamber. Generously sized paddles, adjustable in both
height and pitch, guarantee a homogeneous mixture and an hygienic
process. The mixture is introduced into the compacting chamber
where a rotating three-roller head presses this through two conical
friction rings. Three hydraulic cylinders accurately assess the
adjustable distance (3-45 mm) between the friction rings which,
along with the motor power of the main motor, determine the
compaction level. The unique combination of mixing chamber and
compacting chamber ensures an optimum absorption of steam and
liquids, a more homogeneous distribution of the raw materials,
a higher pelleting capacity and excellent pellet quality.
