Bulk Solid Reconstituted Plant Composition for Devices That Heat Tobacco Without Burning It

Abstract

The invention relates to a bulk solid reconstituted plant composition, the volume of which is suitable for devices that heat tobacco without burning it, said bulk solid composition comprising a plant extract, refined plant fibres and an aerosol-generating agent.

1 . Bulk solid reconstituted plant composition comprising:
 a plant extract,   refined plant fibres, and   an aerosol-generating agent,   
       and the density of which is from 200 mg·cm −3  to 550 mg·cm −3 . 
     
     
         2 . Bulk solid composition according to  claim 1 , in which the plant fibres are refined and have an SR degree of 20° to 90°. 
     
     
         3 . Bulk solid composition according to  claim 1 , in which the aerosol-generating agent is sorbitol, glycerol, propylene glycol, triethylene glycol, lactic acid, glyceryl diacetate, glyceryl triacetate, triethyl citrate or isopropyl myristate, or a mixture thereof. 
     
     
         4 . Bulk solid composition according to  claim 1 , in which the aerosol-generating agent represents from 5% to 50% by weight of dry matter of the bulk solid composition. 
     
     
         5 . Bulk solid composition according to  claim 1 , in which the plant is chosen from spore-producing plants, seed-producing plants and a mixture thereof. 
     
     
         6 . Bulk solid composition according to  claim 1 , in which the plant extract represents from 5% to 75% by weight of dry matter of the bulk solid composition. 
     
     
         7 . Bulk solid composition according to  claim 1 , in which the refined plant fibres represent from 15% to 85% by weight of dry matter of the bulk solid composition. 
     
     
         8 . Process for producing a bulk solid reconstituted plant composition as defined in  claim 1 , comprising the following steps:
 a) mixing refined plant fibres with a plant extract and an aerosol-generating agent so as to obtain a solid composition,   b) moulding the composition so as to obtain a moulded solid composition, and   c) drying the moulded solid composition so as to produce the bulk solid reconstituted plant composition.   
     
     
         9 . Process according to  claim 8 , in which the drying step c) is carried out by hot-air drying, by freeze-drying, by deep-freezing, or by freezing. 
     
     
         10 . Process according to  claim 8 , in which the refined plant fibres and the plant extract are obtained according to the following steps:
 a1) mixing one or more plant parts with a solvent in order to extract a plant extract from the plant fibres,   a2) separating the plant extract from the plant fibres, and   a3) refining the plant fibres.   
     
     
         11 . Process according to  claim 10 , in which the solvent is an aqueous solvent. 
     
     
         12 . Process according to  claim 10 , in which the temperature of the solvent during step a1) is from 10° C. to 100° C. 
     
     
         13 . A method of generating an aerosol by placing the bulk solid reconstituted plant composition as defined in  claim 1 , in a device that heats the bulk solid reconstituted pland composition without burning it. 
     
     
         14 . Bulk solid composition according to  claim 1 , in which the plant fibres are refined and have an SR degree of 40° to 70°. 
     
     
         15 . Bulk solid composition according to  claim 1 , in which the plant is chosen from tobacco plants, food plants, aromatic plants, fragrant plants, medicinal plants, or mixtures thereof. 
     
     
         16 . Bulk solid composition according to  claim 1 , in which the plant extract represents from 15% to 60% by weight of dry matter of the bulk solid composition. 
     
     
         17 . Bulk solid composition according to  claim 1 , in which the refined plant fibres represent form 25% to 75% by weight of dry matter of the bulk solid composition. 
     
     
         18 . Bulk solid composition according to  claim 1 , in which the plant fibres are refined and have an SR degree of 55° to 65°. 
     
     
         19 . Bulk solid composition according to  claim 1 , in which the plant is tobacco plant.
