Werner Sitzmann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10927317
    Abstract: A system for producing biomass pellets comprising a pan mill for comminuting a biomass material, a treatment means in which the comminuted biomass material is treated with an oxidizing reactant and a pellet press for pressing pellets from the treated biomass material. The invention further relates to an associated process. The intention is to initiate during pellet production oxidation reactions which can otherwise result in autoignition of the pellets in pellet heaps.
    Type: Grant

  • Publication number: 20150121748
    Abstract: A method for refining pellets, in which, in a first step, pellets that have been pressed from a biomass are provided. A heat treatment is carried out, involving heating the pellets to a temperature between 210° C. and 390° C. The heat treatment takes a period of time of between 1 minute and 30 minutes. Also described is a device that is suitable for carrying out the method. The pellets treated in this way are water-repellent and so can be stored outdoors.

  • Patent number: 8608095
    Abstract: 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.

  • Patent number: 8343399
    Abstract: 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.

  • Patent number: 5401867
    Abstract: A method for dry fractionation of a mixture of meltable, higher molecular weight organic substances, including: melting a mixture of organic substances which is meltable and which has a higher molecular weight by heating the mixture to a temperature effective to provide a melt, the melt having an interior temperature; pre-cooling the melt with a cooling means including a coolant to one of (1) cool the melt without nucleation of crystallization and (2) cool the melt and nucleate crystallization at a nucleation temperature; and growing crystals under conditions effective to one of (1) nucleate crystallization at the nucleation temperature and ripen the crystals, and (2) ripen crystals nucleated in step (b), wherein pre-cooling, nucleating and crystal ripening each include a thermal treatment, wherein, during precooling, temperature reduction is effected at any desired rate but under the conditions that the coolant has a temperature which is not more than 10.degree. C.
