According to the preparation method of the tobacco particles, the tobacco extract and the atomizing agent are uniformly mixed, and then the mixture is granulated with the carrier, the first adhesive and the inner core and dried to obtain the finished product of the tobacco particles.
Preferably, the first binder comprises polyvinyl alcohol and/or carboxymethyl cellulose.
Further, the granulation method may be a conventional granulation method.
Preferably, after drying, a sieving step is also included.
Preferably, the particle size of the carrier is 100-200 meshes, and further preferably 120-180 meshes.
A low temperature body comprising tobacco particles as described above or prepared by the preparation method as described above.
Preferably, the low temperature aerosol is of a honeycomb structure. Further, the low-temperature fuming body is one of a rod shape, a sheet shape and a block shape.
Furthermore, the moisture content in the smoke body is 5-13%, so that the smoke column is prevented from mildewing during storage, and good smoking taste is ensured.
Furthermore, the effective porosity of the low-temperature smoke body is 65-95%, preferably 75-90%, so that good air permeability is ensured, the smoking is easier and smoother, and the smoking speed is higher.
According to the preparation method of the low-temperature smoke body, the tobacco particles and the second adhesive are uniformly mixed, cured, molded and dried to obtain a finished product of the low-temperature smoke body.
Further, the second binder comprises one of hydroxypropyl cellulose, polyvinyl alcohol, PVP.
Further, the moisture content in the smoke body is 5-13% during drying.
The low temperature smoke body of the present invention is suitable for electromagnetic heating.
