20110147978 | Method For Producing Pellets From Large Pieces of Renewable Fibrous Raw Materials - The invention relates to a method for producing pellets from large pieces of renewable fibrous raw materials, such as, in particular, wood, straw, or energy crops, wherein the raw material is chopped up, then dried, and subsequently processed into pellets in a matrix press, characterized in that the material, optionally pre-chopped in choppers or shredders, is chopped in a first matrix press prior to drying. | 06-23-2011 |
20110108641 | Method for the Disintegration of Lignocellulose to Fibres - The method for disintegration of materials containing lignocellulose to fibers is characterized in that roller pressure is applied to the material containing lignocellulose in a flat die pellet mill by pinch rollers which can have an offset from the die of several millimeters, said pressure being applicable over a wide area, and the material being in a mixture with fiber-improving agents and moist on the surface, whereby the fiber improving agents, supported by the high moisture in the pore interiors, enter far into the interior of the fiber material and react spontaneously or with a delay, wherein finally the disintegrated and refined material is pressed through the bores of the flat die. | 05-12-2011 |
