Patent DE-2523636-A1 (DE)
Title: Impregnating lignocellulosic particles with binder continuously - in a single passage, breaking down and reconstituting ring of fibres
IPC: B27N1/02
Filed: 1975-05-28
Abstract: A continuous process for applying glue to wood cellulose particles such as chips or fibres, feeds the particles into a cylindrical chamber, in which they are accelerated centrifugally so as to form a ring of material against the inner surface of the cylinder, which spirals towards the outlet. The fluid glue enters without press. through stationary channels, and is agitated so intensively that it is converted from the fluid to the atmos. phase. The highly energised wood particles passing through this turbulent atmosphere become completely impregnated, whilst the continuing centrifugal acceleration of the particles reforms them into a coherent rotating ring, which can be ejected as finished without any subsequent mixing operation. The shortening of the zone in which the glue is applied, cheapens the cost of the installation saving as well; current, supervision, cooling water and other charges. The machine is more easily cleaned and cheaper as regards spares. The destruction of the chip profile due to too intensive mixing and the action of friction, is eliminated.
