  • Patent number: 11965138
    Abstract: A flavor or aroma charcoal material, such as charcoal briquets, which is formulated to include a flavor or aroma component. The charcoal material may include a smoldering agent (e.g., limestone), wood particles (e.g., sawdust), a binder, and the flavor or aroma component (herbs and/or spices). The flavor or aroma charcoal material may not be configured as a fuel charcoal material, for example, it may be substantially void of char and/or coal. In an embodiment, the flavor or aroma charcoal material may be provided as part of a blend of different charcoal materials that includes both flavor or aroma briquets in combination with fuel briquets (e.g., which fuel briquets include char and/or coal, while the flavor briquets do not). The flavor briquets provide enhanced aroma and/or flavor to the grilling experience.

  • 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: 8979952
    Abstract: The invention relates to the improvement of the fuel-properties of biomass in an integrated manner to facilitate storage, shipping and applicability thereof. In the process, biomass (6) is thermally treated within a combustion process to cause partial torrefaction of the organic matter present in biomass, thus yielding components inert to biological decomposition processes. Constituents (10) separated in gaseous form are utilized as fuel, while the thermally treated biomass (8) remaining in the solid form is utilized in a separate process.

  • Patent number: 8951309
    Abstract: A hay-based log formed of a combination of pieces of hay and a binding agent. The hay pieces and the binding agent are compressed together into a solid shape. The hay-based log is fabricated so that the majority of the hay-binder combination is made of the hay. The binder is selected to be sufficient to keep the hay pieces joined together in its selected shape. The binder may be wax paraffin, plastic, corn starch or potato starch or any combination thereof. The hay-based log is fabricated by compressing the hay-binder mixture together with sufficient pressure and temperature to enable the hay pieces to stay together and then cooling the mixture without heat or pressure.
