A device for use while burning smoking material and inhaling the resulting smoke is disclosed. The device can include a filter having a recess formed in a surface of a body along a curved face extending from the first end to the second end, the recess extending radially into the body. The smoking accessory can include a capsule containing a flavoring agent disposed within the recess. The device may be received by a first end a tubular member formed to receive a smoking material, that when burned passes smoke into the device.

A system configured to produce smokable products including filter elements formed from multiple fibers is provided. The system includes a texturing apparatus configured to combine the fibers such that the fibers are at least partially entangled with each other and form a mixed fiber product. The entangled fibers may be sufficiently separated from one another such that plasticizer may be applied to the mixed fiber product without necessarily performing tow opening, crimp removal, or blooming operations. The fibers combined to form the mixed fiber product may define characteristics that differ or which are the same. Accordingly, filter elements may be produced that include different fibers that have respective desirable properties associated therewith. Related methods, apparatuses and mixed fiber products are also provided by the disclosure.

An aerosol generating article includes a front-end plug configured to introduce external air into the aerosol generating article, a tobacco medium portion including a tobacco material in the form of granules, and a filter unit arranged at a position opposite the front-end plug across the tobacco medium portion, wherein the tobacco material has a pH value of 7 to 11. Other various embodiments may be identified by the disclosure

A molding apparatus, a cigarette filter rod and a preparation method thereof are disclosed. The molding apparatus comprises a single-screw extrusion system and a cooling setting system. The single-screw extrusion system comprises a feeder and an extruder. The feeder is arranged on the extruder. The extruder comprises a cylinder. A heater is arranged outside the cylinder. A screw is arranged inside the cylinder, and a mouth mold is arranged at one end of the cylinder. The cooling setting system comprises a round tube and a cooler. The cooler (6) is arranged outside the round tube. One end of the round tube is butted with the mouth mold of the extruder; and multiple groups of grooves are formed on threads of the head of the screw.
