摘要:
A sheet tobacco which comprises a carrying sheet comprising plant fibers and being in the form of a non-woven fabric and, formed on the carrying sheet, a tobacco powder layer comprising a tobacco lamina powder and a binder powder; and a method for producing the sheet tobacco which comprises forming a carrying sheet of plant fibers by use of the technology for producing a non-woven fiber, spraying a mixed powder on the carrying sheet to form a tobacco powder layer, and optionally, forming a cover sheet of plant fibers on the tobacco powder layer, and then subjecting together the carrying sheet and the tobacco powder layer, and optionally, the cover sheet to a thermal press treatment, to form a sheet tobacco having a two- or three-layer structure; and a production system for practicing the method.
摘要:
Sheet tobacco according to the present invention includes a carrier sheet made of nonwoven plant fibers, and a tobacco powder layer formed on the carrier sheet and containing a powder mixture of tobacco lamina powder and binder powder. In a sheet tobacco manufacturing process according to the present invention, a carrier sheet of plant fibers is formed by a nonwoven fabric production process, a tobacco powder layer is formed by spreading the powder mixture on the carrier sheet, and a cover sheet of plant fibers is optionally formed on the tobacco powder layer. Subsequently, the carrier sheet, the tobacco powder layer and the optical cover sheet are all together subjected to heating and pressing, thereby producing sheet tobacco with a two- or three-layer structure. The present invention also provides a manufacturing system for carrying out the sheet tobacco manufacturing process.
