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