Detailed Process Description 170
The “Coco Husk Micro-Decorticator” can process 3,000 husks per day. It
separates coco fibre or coir from coconut husk by the crushing action of
multiple blades welded on rotating drums. The blades cause the rapid
separation of fibre and dust, as the husks are crushed against a set of fixed
counter blades arranged horizontally and parallel to the axes of decorticating
blades. Fibres and dust are discharged in separate outlets.
The “Coco-husk mini-decorticator”, which has a higher 5,000-husk daily
capacity, produces mixed fibres 4-6 inches long (CH-3 FIDA grade) by
separating them from the peat of coconut husks, through a scraping drum with
multiple blades welded 94 millilitres apart. Arranged with six sets radially and
eight sets axially with a five-degree helix angle, the blades drag beaten
coconut husks to a series of fixed counter blades set horizontally and in
parallel with the drum’s axis. This system causes rapid fibre and dust
separation.
