Abstract (en)

[origin: DE19813397A1] The present invention relates to a device and a method for carrying out a preliminary disintegration of the stem before the harvest cut or the shortening cut in order to recover the fibrous material. The purpose of this invention is accelerate the material drying process and to limit as much as possible the loading of the complex fibre-extraction machine with secondary non-fibrous components in order to reduce the power consumption, to improve the ecological characteristics and to increase the output of said machine. The preliminary disintegration is performed by integrating new appropriate tools and functions in the rotor of the shortening machine. The non-fibrous constituents produced during the preliminary disintegration are separated using a new open and swinging needle-bar conveyor together with fast-rotating venting and drawing cylinders.
