Definitions

  • the present invention relates to a method for recovering flavor sheets and a method for manufacturing flavor sheets.
  • a method for manufacturing tobacco sheets is known in which the sheet material is rolled between a pair of rollers (see, for example, Patent Document 1).
  • the method described in the cited document separates both end portions of a rolled sheet that are perpendicular to the conveying direction, producing a shaped sheet and materials derived from both end portions.
  • materials derived from both end portions have been discarded.
  • the present invention aims to provide a material for smoking articles that reduces the environmental impact.
  • Aspect 1 Step A rolling the flavor sheet raw material with two or more rollers to form a sheet; A step B of separating both end portions perpendicular to the conveying direction from the sheet to obtain a shaped sheet-like first material and a second material derived from both end portions; Step C of recovering the second material;
  • the flavor sheet recovery method includes the steps of: Aspect 2 Step A: rolling the flavor sheet raw material with two or more rollers to form a sheet; A process D of recovering the third material produced until the quality of the sheet is stabilized;
  • the flavor sheet recovery method includes the steps of: Aspect 3
  • the step A includes forming a sheet on the peripheral surface of the roller,
  • Aspect 4 A recovery method according to any one of Aspects 1 to 3, wherein the flavor sheet raw material is for use in smoking articles.
  • Aspect 5 A recovery method according to any one of Aspects 1 to 4, wherein the flavor sheet raw material comprises a tobacco raw material.
  • Aspect 6 a mixing step of preparing a mixture containing the second material or the third material according to any one of Aspects 1 to 5, a flavor raw material, and a binder; and a sheeting step of forming the mixture into a sheet.
  • a method for producing a flavor sheet comprising: Aspect 7 7. The method according to claim 6, wherein the second material or the third material has a moisture content of 15 to 50% by weight.
  • Aspect 8 A method according to claim 6 or 7, wherein the flavor raw material comprises a tobacco raw material.
  • This invention provides materials for smoking articles that reduce environmental impact.
  • FIG. 1 shows an embodiment of a method for recovering a second material.
  • FIG. 10 is a diagram showing another embodiment of the method for recovering the second material.
  • a flavor sheet recovery method includes a step A of rolling a flavor sheet raw material with two or more rollers to form a sheet; a step B of separating both end portions perpendicular to the conveying direction from the sheet to obtain a shaped sheet and a second material derived from the both end portions; and a step C of recovering the second material.
  • the second material is the material to be recovered.
  • the flavor sheet includes a tobacco raw material, a plant raw material other than tobacco, or a combination thereof.
  • the tobacco raw material is a material derived from a Nicotiana plant.
  • the flavor sheet may be a tobacco sheet, a tea leaf sheet, a vegetable sheet, or a composite sheet containing multiple types of the above raw materials.
  • the flavor sheet is a tobacco sheet.
  • FIG. 1 shows one embodiment of a tobacco sheet recovery method.
  • 10 and 12 are rollers
  • 14 is a raw material supply port
  • 20 is a doctor blade
  • S0 is a tobacco sheet
  • S is a shaped tobacco sheet
  • Se are both end portions of the tobacco sheet perpendicular to the conveying direction.
  • tobacco sheet raw material is rolled into a sheet using two or more rollers.
  • FIG. 1 shows an embodiment with two rollers.
  • tobacco sheet raw material is supplied to the raw material supply port 14.
  • the raw material is rolled between the rollers to form a tobacco sheet S0.
  • the width of the tobacco sheet S0 is wider than the width of the doctor blade 20. Due to the difference in peripheral speed between the rolling rollers 10 and 12, the tobacco sheet S0 is output in a state where it is stuck to the outer periphery of roller 12.
  • the peripheral speed of each roller and the gap between the two rollers may be within known ranges.
  • step B a doctor blade 20 is brought into sliding contact with the surface of the roller 12 to separate the tobacco sheet S0 from the surface of the roller 12.
  • a shaped sheet S and both end portions Se perpendicular to the sheet conveying direction are formed.
  • a shaped sheet is a sheet from which irregular or unnecessary portions have been removed, and is also called a trimmed sheet.
  • step B may be performed during at least one rolling pass or may be performed during all rolling passes. When rolling multiple times is performed, performing step B during a relatively upstream rolling pass is preferable because the second material can be recovered with reduced moisture evaporation. Furthermore, performing step B during a relatively downstream rolling pass is preferable because process loss can be reduced.
  • Tobacco sheet raw materials include tobacco raw materials.
  • Tobacco raw materials are materials derived from plants of the genus Nicotiana. Specific tobacco raw materials include tobacco shreds, tobacco powder, tobacco sheets, and strands, which are commonly used in the field. These may be used alone or in combination.
  • Binder is an adhesive that binds tobacco materials together or between the tobacco material and other components.
  • known binders can be used.
  • binders include polysaccharides such as guar gum and xanthan gum, cellulose derivatives such as CMC (carboxymethyl cellulose), CMC-Na (sodium salt of carboxymethyl cellulose), and HPC (hydroxypropyl cellulose), proteins, and synthetic polymers.
  • the upper limit of the binder content in the tobacco sheet material is preferably 6% by weight or less.
  • the lower limit is preferably 1% by weight or more, more preferably 3% by weight or more. If the amount of binder exceeds the upper limit or is less than the lower limit, the above-mentioned effects may not be fully achieved.

Abstract

Ce procédé de récupération d'une feuille d'arôme comprend une étape A pour laminer une matière première de feuille d'arôme à travers l'utilisation d'au moins deux rouleaux pour former une feuille, une étape B pour séparer les deux parties d'extrémité perpendiculaires à la direction de transport à partir de la feuille pour obtenir un premier matériau façonné et un second matériau dérivé des deux parties d'extrémité, et une étape C pour récupérer le second matériau.
