The invention provides a smokeless tobacco composition that contains bleached tobacco material and guar gum.

Provided herein are systems and methods for testing a heat-not-burn tobacco product. A heater carrier may be movable with respect to a tobacco product placement region and configured to heat a first end of a tobacco product located in the tobacco product placement region. A puffing simulator is configured to fluidically couple to a second end of the tobacco product. The puffing simulator is configured to draw air through the tobacco product thereby simulating a puff of the tobacco product. A thermocouple placement right is configured to selectively position one or more thermocouples in or along the tobacco product. A drill is configured to selectively drill one or more holes at positions within the tobacco product. The thermocouple(s) are positioned on or within the tobacco product and generate data corresponding to detected temperatures of the tobacco product as the puffing simulator simulates one or more puffs.

This invention relates to a method for preparing expanded tobacco stems, characterized in that the method contains steps as follows: purification, stem expansion, hypoxia heat retention (hypoxia heat retention refers to heating the expanded stems at hypoxia environment and maintaining the temperature), natural stacking, sorting, and packaging. An expanded tobacco stem product prepared according to this method has uniform size and color. Taste is modest and plain when it is combusted, which does not affect the original taste flavour. Expansion volume, the ratio of the expanded stems to the total stems, and quality are stable, which can be used as adsorption material. More important, expanded tobacco stems made from stems of different origin, texture and year according to this method have uniform odor component, which can not be acquired by other expansion technologies. This technology has met the requirement for product fabrication.

The present invention relates to method for production of a slurry for homogenized tobacco material, said method comprising: Selecting tobacco of one or more tobacco types; Coarse grinding said tobacco; Blending said tobacco of one or more tobacco types; and Fine grinding said tobacco of one or more tobacco types.

A device and method for preparing a fully granular cigarette/filter rod, and a prepared fully granular cigarette/filter rod are disclosed. In certain embodiments, negative pressure is used to adhere granular material onto a mesh-type conveyor belt. The granular material is preliminarily formed into fully granular cigarette/filter rod material by means of a pre-forming apparatus; the fully granular cigarette/filter rod material, traveling with the mesh-type conveyor belt, enters into a forming cavity, and undergoes heating and humidifying treatment, and a continuous solid porous substance is formed; the continuous solid porous substance is moved into the cooling/drying cavity, drying and cooling treatment are performed under the action of negative pressure, and a fully granular cigarette/filter rod with strong adhesion, porosity, permeability, and appropriate moisture is obtained.

Certain embodiments include a screen assembly of a vessel, where the screen assembly includes a plurality of fixed elements and a retainer, and the retainer includes a ring, a plurality of wedges disposed about the ring, and a plurality of keyholes at spaced locations about the ring. Each keyhole includes a bore and a slot extending from the bore into an adjacent wedge of the plurality of wedges, the slots have a width less than the bores, and the retainer may receive the fixed elements through the bores and may be rotated in a relation with the plurality of fixed elements to bring the plurality of fixed elements into simultaneous engagement with the wedges.

The present invention relates to a method to monitor tobacco material to detect insect infestation, the method comprising: providing tobacco material in a closed space; measuring the concentration of a semiochemical in the air present in the closed space; comparing the measured concentration of the semiochemical with a threshold; andlowering the temperature of the closed space if the concentration of the semiochemical is higher than the threshold.

A tobacco preparation method, where a tobacco material is prepared through at least one extrusion process including compressing the material with an increase in pressure and temperature and mechanically processing and abruptly flash drying the material at an extruder outlet, where the tobacco material includes a tobacco lamina material, where a tobacco preparation device includes a dosing conveyor and an extruder which compresses a tobacco material with an increase in pressure and temperature and mechanically process and abruptly flash dries the material at the extruder outlet, where the components are designated as a unit which can be modularly delimited for processing a tobacco material including a tobacco lamina material, where an arrangement of several tobacco preparation devices and a smoking article or cigarette manufacturing device inlcudes such a device or such a device arrangement which is connected upstream of a cigarette maker or a secondary unit as a tobacco preparation module.
