Problems solved by technology

[0003] The reconstituted tobacco leaves recombined from plant fibers have cavities in the middle of the fibers and gaps between the fibers, and there is air in the gaps, so the thermal conductivity of the reconstituted tobacco leaves is poor, and it takes a long time to heat up. If the heating temperature is simply increased, It is easy to cause the local temperature of the cigarette to be too high during the heating process to carbonize or even burn, resulting in a decrease in the smoking quality of the heat-not-burn cigarette
When the thermal conductivity of reconstituted tobacco leaves is not good, the reconstituted tobacco leaves in the center have been carbonized and heated, while the reconstituted tobacco leaves on the outer edge have not been heated to a sufficient temperature to evaporate, resulting in incomplete utilization of reconstituted tobacco leaves and waste of materials

Abstract

The invention provides heat-not-burn reconstituted tobacco, a preparation method thereof and a heat-not-burn product. The heat-not-burn reconstituted tobacco comprises metal fibers. The preparation method of the heat-not-burn reconstituted tobacco comprises the following steps: soluble substances are extracted from tobacco fiber raw materials; then the insoluble substances are pulped; the metal fibers are added before pulping or in the pulping process; then a substrate is prepared; and the heat-not-burn reconstituted tobacco is obtained through coating of a coating liquid and drying. The heat-not-burn product comprises the heat-not-burn reconstituted tobacco. The heat-not-burn reconstituted tobacco provided by the invention is good in heat-conducting property, short in preheating time andhigh in reconstituted tobacco utilization rate, and material waste is avoided.

Description

technical field [0001] The invention relates to the field of heat-not-burn tobacco, in particular to a heat-not-burn reconstituted tobacco leaf, a preparation method thereof, and a heat-not-burn product. Background technique [0002] When the heat-not-burn cigarette is heated, the heating element first generates heat, and then transfers the heat to the heat-not-burn part of the cigarette. When the temperature of the heat-not-burn part reaches the set temperature, smoke can be produced for smoking. If the heat conduction effect of the reconstituted tobacco leaves constituting the cigarette is good, the overall heating and heat transfer time will be relatively short, and if the heat conduction effect of the reconstituted tobacco leaves constituting the cigarette is poor, the overall heating and heat transfer time will be relatively long. [0003] The reconstituted tobacco leaves recombined from plant fibers have cavities in the middle of the fibers and gaps between the fibers,...
