Ottevanger’s patented pre-compacting technology, a unique alternative for double pelleting or expanding. The Boa Compactors have a double-walled 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 a 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.
