Definitions

  • the invention relates to a system and a method for the production of glued plant particles, in particular from annual plants, for the production of panels, e.g. B. fiberboard or chipboard, with at least one comminution device for comminuting plant starting material into scatterable plant particles and with a gluing device for gluing the plant particles.
  • panels e.g. B. fiberboard or chipboard
  • the vegetable raw material is lignocellulosic raw material, e.g. B. wood. It is particularly preferred, however, to use lignocellulose-containing starting material from so-called annual plants, ie those plants which only require one vegetation period from germination of the seed through the development of the entire plant, flower formation, fertilization to the maturity of the new seed. Examples of such fast-growing plants are cereal plants (or the straw that arises from them), e.g. B. rice or rice straw, but also bamboo, as well as bagasse, reeds or pile cane. Dispersible particles from such plants or plant raw material are used in practice for the production of panels, eg. B.

  • z. B. the need in classic agricultural cultivation, z. B. Rice cultivation, to use the remaining straw after the harvest and not - as was customary up to now - to leave it in the fields or to burn it, but to use it for the production of fiberboard or chipboard.
  • the possibility of material panels based on straw, e.g. B. rice straw, produce is z. B. in the DE 10 2009 057 916 B4 and the DE 10 2015 120 653 A1 , which discloses the preamble of claim 1, described.
