    • A method of thermally processing a tobacco material is provided, the method including the steps of (i) mixing a tobacco material, water, and an additive selected from the group consisting of lysine, glycine, histidine, alanine, methionine, glutamic acid, aspartic acid, proline, phenylalanine, valine, arginine, di- and trivalent cations, asparaginase, saccharides, phenolic compounds, reducing agents, compounds having a free thiol group, oxidizing agents, oxidation catalysts, plant extracts, and combinations thereof, to form a moist tobacco mixture; (ii) heating the moist tobacco mixture at a temperature of at least about 60° C. to form a heat-treated tobacco mixture; and (iii) incorporating the heat-treated tobacco mixture into a tobacco product. Heat-treated tobacco composition prepared according to the method are also provided, such as heat-treated smokeless tobacco composition comprising a tobacco material, water, flavorant, binder, and filler, the heat-treated smokeless tobacco composition having an acrylamide content of less than about 2000 ppb.

    • A micro gas burner is provided that generates a stable, pre-mixed flame that produces little to no soot or unburned hydrocarbons. The gas burner includes a fuel inlet, nozzle, oxygenation chamber with at least one air inlet, a mixing chamber having a frustoconical inner wall, at least one permeable barrier and a flame holder. The gas burner thoroughly mixes fuel and entrained air to form a nearly stoichiometric mixture prior to combustion. The gas burner mixes the fuel and air so thoroughly that it requires a lower fuel flow rate than would otherwise be necessary to produce a stable, pre-mixed flame. The gas burner may include an optional flame tube with an optional exhaust port in which a flame is contained and sequestered from diffusing air.
    • 提供了一种微气体燃烧器,其产生稳定的,预混合的火焰,其产生很少或没有烟灰或未燃烧的碳氢化合物。 气体燃烧器包括燃料入口,喷嘴,具有至少一个空气入口的氧合室,具有截头圆锥形内壁的混合室,至少一个可渗透屏障和火焰保持器。 在燃烧之前,气体燃烧器将燃料和夹带的空气充分混合以形成几乎化学计量的混合物。 燃气燃烧器将燃料和空气充分混合,使其燃料流量要低于生产稳定的预混合火焰所需的燃料流量。 气体燃烧器可以包括可选的火焰管,其具有可选的排气口,其中火焰被容纳并从扩散空气中隔离。
